(MWTPE]MRK(EXEMJ4)+%7=7MWRSX*YPP]'SRJMKYVIHThe PEGASYS 2.0 Administrator’s Guide, shipped with PEGASYS 2.0, provides aset of guidelines that should be followed during commissioning. If PEGASYS2.0 has been installed and configured using the recommended guidelines, thestandard Vista user diagrams display real-time and logged data from your 7700ION automatically.

If commissioning has not been completed (or if commissioning was performedwithout following the guidelines) some effort may be required to view 7700ION data in Vista 2.0. If you are not able to run the PEGASYS CommunicationsServer, Log Server or Vista, you will need to complete commissioning beforeyou can display data from your 7700 ION. Contact your PEGASYSAdministrator or refer to the PEGASYS 2.0 Administrator’s Guide beforecontinuing with this User’s Guide.

If you can run PEGASYS Vista and log on, you can probably access data fromyour 7700 ION. Try performing the following steps in Vista:

1. Log on to Vista with Supervisor authority (Level 5).

2. Select Generate Network Diagram from the File menu.

3. In the Network Diagram, double-click the Workstation icon correspondingto the computer that communicates with the 7700 ION. A new diagramwith all available IEDs appears.

4. Double-click the icon for the 7700 ION. The Real-Time diagram appears,and live data should appear within moments.

You should now be able to move around through the various diagrams andview real-time and logged data.

-RXIVTVIXMRK2YQFIVWMR2YQIVMG(MWTPE]WEleven of the 24 display screens show up to 15 parameters in a list, with theparameter name on the left, and the corresponding value on the right. One ofthe screens, Total Power, uses a large character display with four parameters onthe screen. Both the ‘standard’ 15-parameter display and the large characterdisplay show numeric values.

When displaying numeric values, the MGT can display up to four digits ofresolution. If more than four digits of resolution are required, use PEGASYSsoftware to display data. If a value is too large or too small to be displayed withfour digits, the MGT uses an abbreviated engineering notation that usesstandard metric prefixes to indicate the magnitude of the reading. For example,

MGT Display Value12m40....................................... 0.0124

12K40 ....................................... 12, 400

12M40 ...................................... 12, 400, 0001G240....................................... 1, 240, 000, 000

Numeric values are displayed in base units; voltages are displayed in volts,while current is displayed in amps. The following values, however, aredisplayed in kilo units rather than base units since kilo is the most frequentlyused measurement:

♦ kW

♦ kVA

♦ kVAR

When viewing these parameters with the MGT, remember that the values arealready multiplied by 1000. For example, the reading below indicates 120, 000kilowatts, not 120, 000 watts.

kW total ..................................120K0

-2:0(ERH2%1IWWEKIW

If the MGT is unable to read a numeric or status value from the 7700 ION, it willdisplay either INVLD or N/A in place of the value. INVLD indicates that the valuereceived cannot be displayed because it is either too large or too small (it isbelow 1m000 or above 9G999). N/A appears if the register is not available.

&EV+VETL(MWTPE]WThree display screens are provided for phase voltage and current:

♦ High-speed line-to-neutral and average voltage (100 ms update rate)

♦ High-speed phase and average current (100 ms update rate)

♦ Line-to-neutral voltage and phase current (1 second update) with minimumand maximum indicators.

The two high-speed displays use a four-channel bar graph that shows the lowlimit, the parameter name (i.e. Vln a, meaning line-to-neutral voltage on phaseA), and the upper limit above the bar for each measurement. The high-speedvoltage display, called VOLTAGE HS BAR GRAPH, has fixed limits of 0 to 400 volts.The high-speed current display, called CURRENT HS BAR GRAPH, has fixed limitsof 0 to 6000 Amps. If your voltage or current values are above the fixed upperlimits, the MGT will display OFF SCALE in place of the bar. Similarly, the voltagebar graph displays OFF SCALE if you have a Delta power system, as there are noline-to-neutral voltage values available.

The phase voltage and current bar graph, called VOLTS/AMPS BAR GRAPH,displays line-to-neutral phase voltage and phase current values. As with thehigh-speed bar graphs, voltage limits of 0 to 400 Volts and current limits of 0 to6000 Amps are fixed, and line-to-neutral voltages will read OFF SCALE if viewedin a Delta power system.

The VOLTS/AMPS BAR GRAPH also shows the minimum and maximum valuesmeasured (since power-up or the last min/max reset). Small triangles locatedon each parameter’s bar indicate the min/max values:

,MWXSVMG(EXE0SKKMRK*VEQI[SVOThis portion of the meter’s configuration records ‘standard’ power systemparameters such as voltage, current, power, frequency and power factor. Low,mean and high values are recorded for all parameters. Note that ‘low’ and‘high’ are different from ‘min’ and ‘max’: low and high are reset every 15minutes, whereas min and max are typically long-term measurements that areonly reset by the operator. Similarly, ‘mean’ is reset every 15 minutes, unlike‘average’ which is typically an instantaneous averaging of multiple real-timemeasurements.

Once basic setup is performed, most users will find that the 7700 ION’s factoryconfiguration provides all of the monitoring, logging and control functionalitythey require. Depending on your application, you may need to make minorchanges to the factory configuration to make the device “fit” your power system.This chapter explains how to make small changes to the factory configurationusing PEGASYS software, PowerView software and the MGT.

The 7700 ION can be customized to perform virtually any power monitoring andcontrol functions. Creating custom functionality involves dismantling the factoryconfiguration and replacing it with your own module links and settings. If youwant to make significant changes to the operation of the 7700 ION, refer toChapter 4.

'SRJMKYVEXMSR8SSPWDifferent types of configuration changes can be made using the different toolsprovided by Power Measurement. Each of the tools available has been designedto make basic configuration changes easy. The configuration tools available andthe types of configuration changes you can make with them are as follows:

♦ PEGASYS ION Designer software lets you change the settings for anyfunction performed by the meter. Everything from basic setup to creatingcustom functionality can be performed using ION Designer. The differenttypes of device functions are grouped together on the ION Designer screen,so you can quickly access the types of settings you want to change.

Refer to the PEGASYS ION Designer on-line help for assistance using thesoftware.

♦ PowerView software (PowerView for Windows and PowerView Plus)provides basic and advanced setup modes, allowing you to change thesettings for any meter function. Advanced users can create customfunctionality with PowerView.

Refer to the PowerView on-line help for assistance using the software.

♦ The MGT also provides access to the settings of every meter function. Specialscreens are provided for quick access to basic setup functions. The MGTcannot be used to create custom functionality.

Any of the tools mentioned above are suitable for making minor changes to thedevice’s configuration. If you plan to do more extensive changes later on, usePEGASYS ION Designer for device configuration — this software provides themost comprehensive view of the 7700 ION’s internal operation. Once you havebecome comfortable with the ION Designer interface you will be better preparedto make major changes later.

&EWMGWSJXLI-32%VGLMXIGXYVIBefore you begin altering the 7700 ION’s operation, it is advisable to familiarizeyourself with the basics of how the device operates. Understanding the basics ofthe ION architecture will help you understand how to make different types ofconfiguration changes.

The 7700 ION and all other ION devices (including some PEGASYS softwarenodes, such as the VIP and the Log Server) use the Integrated Object Network, orION, as their operating software. ION applies the principles of object-orientedsoftware design to the creation of functionality inside your Power Measurementdevices. The object-oriented structure of ION allows you to connect differentdiscrete objects (called ION modules) in different ways to define how informationis accessed, transferred, and manipulated inside the device and across the powermonitoring network.

Each ION device contains a number of ION modules that perform specificfunctions. The ION modules are linked together to create frameworks, definingmultiple operations and logical pathways for power system information. Thebasic structure of an ION module is the same for each module type, making iteasy to use new features once the basics are understood.

8LI-321SHYPIThe ION module is the basic building block of the ION device’s operatingsoftware. A module can be considered as a “function box”: it receives data fromits inputs, makes decisions based on the settings in its setup registers, and thenmakes data available at its output registers. All functionality provided by an IONdevice can be considered in terms of its modules and the linkages between them.

Data flows into the module throughthe inputs (inputs are connected to theoutput registers on other ION modules)

The module holds the results of itscalculations in its output registers —

r -3297)67+9-()

There are approximately 50 types of modules in the ION architecture; the 7700ION has 32 different module types. Most ION devices can support severalinstances of a certain module type (for example, the 7700 ION supports 16Thermal Demand modules, 20 Periodic Timer modules and one Clock module).

-326IKMWXIVWEach module has one or more output registers, and most modules have Setupregisters. (A module’s inputs can be thought of as a link to the output registerson other modules.)

There are different types of registers, classified by the type of data they accept.When you want to change a module’s configuration, you must supply the type ofdata that is appropriate for the register you are configuring. All of theconfiguration tools discussed in this chapter prevent you from entering thewrong type of data into a register, but they do not prevent you from entering thewrong value. As any changes to a register’s value alters the operation of thedevice, exercise caution when making configuration changes.

1EOMRK-32'SRJMKYVEXMSR'LERKIW

Regardless of the interface you use, when you make configuration changes to anION device you are either changing a value in a module’s setup register or youare changing the linkage between two or more modules. The types ofconfiguration changes discussed in this chapter are changes to the settings held inION module Setup registers.

Communication settings are typically configured when the device is initially putinto service. A communications channel must be configured before you can usePEGASYS; if you alter the settings for the channel that is in use you will lose yourcommunications connection with the device.

The setup registers in the Communications and Ethernet modules define theparameters used for each communications port. The following parameters can beconfigured (different parameters are presented on different modules):

♦ communications standard (i.e. RS-485 or RS-232) and related settings

♦ communications protocol (i.e. ION, Modbus RTU, or DNP 3.0)

♦ communications link speed (i.e. 19, 200 bps)

♦ device unit ID (RS-485) or IP Address, gateway and subnet mask (Ethernet)

'SQQYRMGEXMSRW4VSXSGSPWBy default each communications port on the 7700 ION is configured to use theION protocol. If you want to make use of the factory Modbus RTU or DNP 3.0configurations, you need to configure the Communications module that controlsthe port you want to use.

Use the table above to determine which module controls the port you intend touse, and choose the appropriate protocol from the module’s Protocol setupregister. Note that DNP 3.0 is only available on the Comm 2 and Comm 3 XPRESSCARD ports, and only one port can communicate using DNP 3.0 at a time.

There is no need to change any of the Relative Setpoint module’s setup registersfor normal operation of the 7700 ION. If you want to fine-tune over conditionmonitoring, the only setup registers you should change are SusUntlON andSusUntlOFF.

SusUntlON determines how long the modules will wait after an over condition isdetected before reporting it. This gives the monitored value a short period tocorrect itself before the event is registered with the module, so that very briefover conditions are ignored. Similarly, SusUntlOFF is the amount of time anormal value must be present before the module considers normal operation tobe restored. Both SusUntlON and SusUntlOFF values are entered in seconds (thedefault value for both is 30 seconds).

To create custom functions, ION modules are linked together and thenconfigured. Linking ION modules is a simple task: output registers on onemodule are linked to the inputs of subsequent modules. The data flows from theoutput register on the first module to the input on the second. Each module thatreceives data makes decisions and processes the data based on the settings in itssetup registers. Once a module has processed the data it has received, it makesthe data available at its output registers. These output registers can then belinked to the inputs of other modules, and so on.

Most ION modules perform simple, discrete functions. It is the combination ofmodules linked together that creates powerful functionality. As the operation ofthe device can be separated into the specific, smaller functions performed by themodules, creating functionality is simple if you understand the functions of thecomponent pieces.

6IGSQQIRHIH'SRJMKYVEXMSR8SSPW

Both PEGASYS and PowerView software provide the tools necessary tocustomize the 7700 ION’s operation. Whenever possible, PEGASYS IONDesigner should be used to create custom functionality as it provides a morepowerful interface to the device’s internal operation. ION Designer presents IONmodules and module links graphically — you are able to view the flow of data onthe screen. Many of the discussions in the chapter assume you are using IONDesigner.

PowerView provides the functions required to link ION modules, but there is nographic representation of how the data flows through the linked modules. UsingPowerView to create custom functionality requires the ability to conceptualizemodule linkages without being able to view them on screen.

In order to create custom functions in the 7700 ION it is necessary to understandsome of the “rules” of ION. Read the following paragraphs for information onthe component parts of an ION module and what restrictions apply to their use.To recall what was stated in Chapter 3, an ION module consists of inputs, setupregisters and output registers.

Data flows into the module throughthe inputs (inputs are connected to theoutput registers on other ION modules)

The module holds the results of itsoperation in its output registers —

this data is available to other modules

Settings in the setup registers controlhow the module processes data

Modules are linked together to create powerful functions. For example, theframework below consists of four modules that, when combined, trigger awaveform recording in response to an over-voltage condition.

1SHYPI0MROMRK6IWXVMGXMSRWThe maximum number of modules that can be linked in a row is 8. This isreferred to as the framework’s depth. Modules that branch off or branch into thechain do not affect the depth, and there is no restriction on the number ofbranches you can have in a framework.

Another restriction concerns “circular” linking of modules. You cannot link amodule’s output register to its own input or to the input of any module thatprecedes it in the chain. This protects you from creating infinite loops that canwaste system resources. Some devices (including the 7700 ION) support theFeedback module, which makes circular linkages possible (refer to the IONReference).

r -3297)67+9-()

8LI2SX%ZEMPEFPI:EPYIIf a module is not linked to anything, its output registers will not contain anyvalues and are set to Not Available. In addition, if a module has an input that isinvalid (for example, a line-to-neutral measurement for a 3-wire Delta system) itsoutput register is also set to Not Available. This helps distinguish between caseswhere a register contains a value like 0 or OFF, and cases where there is actuallyno value stored.

If the inputs of a module are Not Available, its output registers are also NotAvailable. The Not Available value propagates through all linked modules. (TheNot Available value propagates through linked Arithmetic modules differently -refer to the ION Arithmetic module description in the ION Reference.)

'SVI1SHYPIWERH*M\IH1SHYPI0MROWThe 7700 ION includes several core modules. Core modules are integral to thebasic operation of the device; they cannot be created or deleted. Core modules inthe 7700 ION version 7700V200 include the Clock, Communications, DataAcquisition, Diagnostics, DNP Slave Options, Factory, FFT, Harmonics, PowerMeter, and Symmetrical Components.

Several of the linkages between core modules are fixed; they are required for thebasic operation of the device. A fixed link cannot be removed. A core modulewith fixed links can still be linked to other modules if desired.

-326IKMWXIV(IXEMPWNot all output registers can serve as input registers for all modules. There aredifferent classes of registers and each is capable of holding different types ofinformation. To combine two ION modules together, the output registers of thefirst module must contain the kind of information that the next module can use.

To see if you can link ION modules, check the class of the module’s inputs andoutput registers to ensure they are the same. The following list describes thevarious register classes available.

NumericThese registers contain a single numeric value. It can be any value within therange capabilities of the device.

Numeric ArrayThese registers contain an array of numeric values.

BooleanThese registers contain a logical ON or OFF (1 or 0).

PulseThese registers “contain” a pulse, or instantaneous signal. They are normallyused for resetting, pulsing or triggering functions.

238),21 'HVLJQHU XVHV D GRXEOHRXWOLQH WR LQGLFDWH D FRUHPRGXOH

97-2+%(:%2')(*)%896)7 r

WaveformThese registers contain formatted waveform data (an array of points that define awaveform). The information is formatted on the basis of:

#samples per cycle X #cycles

EnumeratedThese registers are used for storing one value from a list of several options. Forexample, the Setpoint module has an Evaluate Mode setup register that can be setto either LESSTHAN or GREATERTHAN. Typically only setup registers are of theenumerated class.

Numeric BoundedThese registers contain a number bounded by a high and low limit. For example,in the Thermal Demand (TD) module, the setup register that specifies the periodlength is numeric bounded because the value must be a number higher than 1 butless than 100. Typically only setup registers are of the numeric bounded class.

CalendarThe Calendar register holds the setup information in the Scheduler module.

StringThese registers contain text strings. Text strings can consist of any combinationof numbers, letters and spaces, excluding double-quote characters ( " ). Inaddition, the text must not end with a backslash character ( \ ). (Backslasheselsewhere in the text are permissible, as is a backslash at the end of the string if itis followed by a space character.)

String register applications include formulas (Arithmetic module) and deviceinformation (Factory module).

EventAlmost every ION module has an output called an event register that records allthe events produced by the module. An event is simply any occurrence in thesystem that warrants logging (for example, changing a setup register or aSetpoint module going active). The contents of an event register include:

♦ A timestamp of when the event occurred

♦ The priority of the event

♦ The cause of the event

♦ Any values or conditions associated with the cause

♦ The effect of the event

♦ Any values or conditions associated with the effect

The Event Log Controller module takes all the event registers from all themodules in the device and assembles them to provide an Event Log.

r -3297)67+9-()

Event LogThese registers contains the assembled contents of all the event registers of othermodules. The Event Log Controller module uses this class of register to providea log of all the events occurring on the device.

LogThese registers can contain a timestamped list of numeric, Boolean or waveformdata. Typically, modules that record data (e.g. Data Recorder, WaveformRecorder) have Log output registers.

-326IKMWXIV2EQIWERH0EFIPW

Every register in the ION architecture has a name and a programmable label thatidentify what information the register contains. The default label for eachregister is typically the same as its name.

You can change the label via communications to be more descriptive for yourapplication. For example, the name (and thus the default label) of the Maximummodule’s output register is Maximum. If you are using that particular module torecord maximum values on Vunbal, you may want to change the “Maximum”label to “Max Vunbal” to make it more apparent what the contents of the registerrepresent. The length of the label is limited to 15 characters.

8MQMRK'SRWMHIVEXMSRWMRXLI-32

The standard, high-accuracy update rate of the modules in the 7700 ION is 1second. Many modules can also be configured to operate as high-speed, and assuch are updated every cycle. When programming, or linking ION modules, it isimportant to keep in mind whether you want the framework you are creating tobe a high-speed or high-accuracy framework. If you link three modules togetherto perform a function, the update rate of the first module in the frameworkdefines the speed of the whole framework. For example, if you link:

Power Meter (high-speed) ⇒ Maximum ⇒ Recorder

the whole framework will operate at high-speed (1 cycle update rate), includingthe Maximum and Recorder modules. If you used an Analog input module(which all have a 1 second update rate) instead of the high-speed Power Metermodule, the framework would operate as high-accuracy (1 second update rate).

In most cases, the number of high-speed-capable modules is limited so youshould only use them when necessary.

97-2+%(:%2')(*)%896)7 r

8MQI7IRWMXMZI1SHYPIWMany modules in the 7700 ION have setup registers requiring you to specify atime interval. Typically, these registers are specified in seconds and you canenter any value that is within the allowable range. Due to the update rate of themodule however, the time that you specify cannot always be supported. If youspecify a time that is shorter than the update rate of the module (or falls in-between update cycles), the module will round up to the shortest time possible.

For high-accuracy modules, it is advisable to specify time values in the varioussetup registers in multiples of the update rate.

For high-speed modules, it is still advisable to restrict your time values tomultiples of the update rate (e.g. one cycle, two cycles, three cycles, etc.);however, because you are required to specify time in milliseconds, these modulesshould be addressed slightly differently.

Since the frequency of the system defines how many milliseconds there are in acycle, and the frequency of the system can drift slightly, specifying an exactnumber of milliseconds may not always correspond with the number of cyclesyou expect. For example, if you specify a value in milliseconds that exactlycorresponds to three cycles, your event may sometimes occur every three cyclesand sometime every four if there has been any drift.

You can take advantage of the fact that some modules always round time valuesup to the closest update rate they can support to ensure that your time valueresults in the number of cycles you want. For example, in a 60 Hz system, if youspecify 13 instead of 16.67 milliseconds, the module will automatically updateevery cycle, even if the frequency has drifted and the number of milliseconds in acycle has changed to 15.

7IUYIRGISJ1SHYPI)\IGYXMSRION modules are executed in the order in which they are logically linked, ratherthan the order in which you actually linked them. In other words, modules areexecuted in the same order in which the data flows from one module to the next.

This allows you to create a framework by linking modules in any order you wantand maintain a logical execution order. For example, you can link the DataRecorder, the Maximum and the Thermal Demand modules together first, andthen later link them to the Power Meter module. It does not affect the executionorder; the Power Meter module will still execute first.

In more complex frameworks, the relationship between modules may not be aslinear as in the previous examples. In these cases, modules are still executed inthe order of information flow but some modules may be executed simultaneouslyif they do not depend on each other for data. For example:

Note that execution order and update rate are not the same thing. Update raterefers to how frequently a module performs its operation and updates its outputregisters (every second for high accuracy, every cycle for high speed). Executionorder refers to the order in which modules execute within the update period. Forexample, if the framework above were high-speed, the entire process wouldexecute within the 1 cycle update period; it would not take 4 cycles to execute.

0MROMRK1SHYPIWModule linking involves clicking on one module’s output register symbol,choosing the output register you want to link, then clicking the input of a secondmodule and selecting the input to link to. This operation can be performed inreverse – you can start with one module’s input and link to another module’soutput register if desired.

You can link modules that reside on different nodes, provided that you arelinking between software nodes, or from a meter to a software node. You cannotlink modules between meters. The paragraphs below describe how to linkmodules that reside on the same node. Refer to the ION Reference or the IONDesigner On-Line Help for instructions if you want to link modules that reside ondifferent nodes.

Follow the steps below to link modules on the 7700 ION:

1. To list a module’s output registers, click on the symbol on the right side ofthe module icon. (To list the module’s setup registers, hold the CTRL keywhile clicking on the symbol.) In most cases, a pop-up menu will appearlisting the available registers. If the module has many registers, a dialog boxwill appear instead.

2. Click on the register you want to select. In the case of the dialog box, double-click on an output register, or choose the register and click Select.

3. Drag the cursor towards the module you want to link to; the cursor willchange and a dotted line will follow it across the node diagram. Thisindicates you are in the process of creating a link. The dotted line also showswhere the connecting line will appear in the node diagram once the link ismade.

If you link to a module that is in a different window than the original module(either in a different node diagram or grouping window), the dotted line willdisappear, but the cursor will still indicate that a link is in progress.

4. Click on the symbol on the left side of the module icon to display themodule’s inputs. In most cases, a pop-up menu will appear listing themodule’s inputs. (If there are a large number of inputs, a dialog box similarto the More Output Registers dialog will appear instead.) Inputs that are of adifferent class than the selected output register are grayed out to indicate thatyou cannot select them.

If the input is already linked, the label of the register it is linked to isdisplayed beside the input. If you select the input, the existing link will beoverwritten.

5. Choose the input you want from the pop-up or dialog box.

6. If the two modules are in the same window, the dotted line remains on thescreen to show the link between the modules. When you save this change tothe node, the line will change from a dotted line to a thin black line toindicate that the link is now programmed on the node.

The procedure described above can also be performed in reverse order. You canselect a module’s input first and then link it to another module’s output register.

)HMXMRK)\MWXMRK*VEQI[SVOWIf you are comfortable with ION and the 7700 ION’s configuration, you can makechanges to the existing frameworks to customize operation. Any edits you maketo the existing frameworks will alter the device’s operation — be sure youunderstand what effect your changes will have before proceeding.

Chapter 2 includes a table that lists all of the parameters and functions providedin the 7700 ION factory configuration. This table shows the module and outputregister that holds each parameter. If you want to delete or change a parameter,use this table to determine which module and which output register provides thedata, then check which other modules the output register is linked to (describedbelow).

'LIGOMRKER3YTYX6IKMWXIVWl3[RIVz

Using ION Designer, right-click a module’s output register to view its linkages,referred to as “owners”. A dialog box appears showing all of the inputs that arelinked to that output register. With this information you can determine whatchanges will result to the framework by deleting the links to the parameter. Notethat links to inputs on other nodes are not shown in this dialog box.

(IPIXMRKXLI0MROEXE1SHYPIW-RTYX

You can also check the links at a module’s input. Using ION Designer, right-clickon the input symbol on a module to view a dialog box listing each of the inputsand the output registers they are linked to. You can unlink inputs from withinthis dialog box as well.

9WMRK3RFSEVHERH)\TERWMSR-3The 7700 ION is available with numerous I/O options. The standardconfiguration includes eight onboard status inputs. Four onboard analog inputsand two expansion boards, each with up to 15 I/O modules, are available asordering options.

3RFSEVH7XEXYW-RTYXWThe eight onboard status inputs can be used for monitoring external contacts orpulse counting applications. These inputs use a current sensing technique tomonitor contact status by providing an internal 30 VDC supply for self-excitation.These inputs can be used for dry contact sensing, but not for voltage sensing.

The function of each status input is controlled by the Digital Input modules 1through 8. These modules are preconfigured at the factory, together with eightCounter modules for counting status changes, and an External Pulse module forresetting the Counter modules.

Once you have connected the status inputs to the field equipment that theymonitor, check the 7700 ION’s Digital Input modules to ensure they areconfigured appropriately. The eight Digital Input modules are factoryconfigured as follows (refer to the ION Reference for complete details on modulefunction):

ION Analog Input modules control the function of each analog input. As theanalog input board is optional, no Analog Input modules are included in the 7700ION’s factory configuration. Refer to page 4–11 for instructions on adding anION module to the 7700 ION.

Analog Input modules are configured by selecting the port they monitor, andsetting the scaling values used to normalize the incoming signal. Onceconfigured, you can link the output of the Analog Input module to any othermodule that accepts numeric data.

The Input and Output modules are configured by specifying the port they use tosend or receive signals (see page 4–19), and configuring other settings specific tothe type of operation they perform. Refer to the ION Reference for completedetails on the function of each module type.

Each expansion board offers 15 slots you can plug I/O devices into. Slots 0through 7 support digital input, digital output and analog output devices only(analog input devices are not supported). Slots 8 through 14 support digitalinput, digital output, analog input and analog output devices. Slot 15 is notsupported. Other restrictions apply to the use of analog I/O devices, asdiscussed below.

%REPSK(IZMGI6IWXVMGXMSRW4S[IV7YTTPMIW

Power requirements and hardware restrictions limit the number and placementof analog devices on I/O expansion boards.

The allowable number of analog devices the 7700 ION can support increasessignificantly when two external power supplies are used to power the expansionboards. The default configuration of Expansion Board A does not include apower supply; it has to be purchased separately. If Expansion Board A ispowered directly from the 7700 ION, then a maximum of six analog devices canbe installed on it. (A separate power supply is required for Expansion Board B inany configuration.)

To use the maximum number of analog I/O devices, two power supplies must beused (one for each expansion board). Note that if a separate power supply isused with Expansion Board A, then the jumper must be removed from the board.Failure to remove the jumper will void the 7700 ION’s warranty. (Refer to the7700 ION Installation & Basic Setup Instructions for jumper location.)

The direction of all of the devices in slots 0 through 7 and slots 8 through 14 mustbe the same. You cannot mix inputs and outputs within these two groups ofslots; however, you can have all inputs in slots 0 through 7, and all outputs inslots 8 through 14 (or vice versa).

As noted on the graphic above, only slots 8 through 14 support analog inputdevices, thereby limiting the maximum number of these devices to seven perboard. Analog Output devices can populate both slot groups on the expansionboard, so a maximum of 15 of these devices can be used per board.

If Expansion Board A is used without a separate power supply, only six analogdevices can be used in total, regardless of direction restrictions.

-QTSVXMRK(EXEYWMRK1SHFYW689It is possible to bring data into the 7700 ION using Modbus. Various IONregisters can be written by Modbus Master devices by correlating the Modbusregister number with the address of the ION register you want to write. When aModbus register is written with a value, the corresponding ION register will bewritten, provided the Modbus RTU protocol is active on the communicationschannel that connects the Modbus Master to the 7700 ION.

You can use the Modbus RTU protocol to write values into ION externalnumeric, pulse and Boolean registers, allowing you to enable, disable and reset7700 ION functions. You can also use the Modbus protocol to change setupregister values in various ION modules to configure the 7700 ION’s operation.

All of the information required to write to ION registers through Modbus isavailable in 7700 ION/Modicon Modbus Serial Communications Protocol andION/Modbus Register Map, available on the PEGASYS distribution CD, or byrequest from Power Measurement.

9WMRK4S[IV1IEWYVIQIRXW)XLIV+EXI4VSXSGSPThe EtherGate protocol can be used on one or more of the XPRESS CARD’s RS-485ports, in place of ION, Modbus RTU or DNP 3.0 protocols. The EtherGateprotocol allows the 7700 ION to act as a gateway, transferring data directlybetween Ethernet and RS-485 networks.

There are three ways EtherGate can be used to transfer data between networks.Using the IP Address of the 7700 ION, one of three IP Service Port numbers(sockets) can be used to direct the flow of data as follows:

♦ If the IP Service Port is set to 7800, Ethernet data is transferred to both XPRESSCARD RS-485 ports.

♦ If the IP Service Port is set to 7802, Ethernet data is transferred to the XPRESSCARD’S COM 2 RS-485 port only.

♦ If the IP Service Port is set to 7803, Ethernet data is transferred to the XPRESSCARD’S COM 3 RS-485 port only.

'SQQYRMGEXMRK8LVSYKLXLI-32In the basic EtherGate configuration, your PEGASYS workstation connects to theXPRESS CARD’s Ethernet port, and an RS-485 loop of devices connects to theXPRESS CARD’s COM2 or COM3 RS-485 port (or both, if you have two RS-485loops). You then add a Gateway Site in PEGASYS Network Builder, and add allof the devices on the RS-485 loop to this site.

In this configuration you communicate with the RS-485 loop through the 7700 ION(the 7700 ION acts as the gateway). You cannot communicate directly with the7700 ION, unless you add an additional Ethernet Site, as discussed in the nextsection.

9WMRK8MQI7]RGLVSRMÊXMSRTime synchronization allows you to synchronize the internal clocks of multiplenetworked Power Measurement devices. When your devices’ clocks aresynchronized, all data logs will have timestamps that are relative to a uniformtime base. This allows you to perform accurate sequence-of-events and powerquality analyses.

Time synchronization is achieved by broadcasting the time across the network ofIEDs. When the source of the time broadcast (PEGASYS or a GPS receiver)initially connects to the devices, the time signal is interpreted as the absolutetime, and the devices’ clocks are reset. During normal operation time signals aresent out periodically, and each 7700 ION will continually assess its ability toremain synchronized with the incoming broadcasts. Over a brief period of timethe 7700 ION learns how its internal timing differs from that of the broadcastsource, and adjusts its timekeeping to compensate. Very accurate timesynchronization can be achieved with this method.

Devices that are not continuously connected to the time source (i.e. modem sites)will be synchronized each time they are connected. The longer the durationbetween connections, the larger the error in time synchronization can be. In theextreme case this can result in missing or duplicated logs. If this occurs, GPSreceivers can be installed at the remote sites, a direct PEGASYS connection can beimplemented, or the time between connections can be reduced. As a remotedevice’s clock is reset upon connection if its clock is out of synchronization byone or more seconds, increasing the frequency of connections will typicallyensure records are not duplicated or lost.

8MQI7]RGLVSRMÊXMSR%GGYVEG]Different time sync methods can be used to provide different levels of accuracy.PEGASYS can be used for systems where time synchronization is not critical. Inthis configuration, each device’s clock is synchronized to the time broadcast bythe PEGASYS Communications Server workstation. For applications wherehighly accurate synchronization is required, an additional serial network isinstalled at the site, and a GPS receiver is used to broadcast the timesynchronization signal.

Using PEGASYS as the time source, the 7700 ION’s clock can be synchronized towithin ± 16ms (typical) of other 7700 ION meters in the network. Using a GPSreceiver, the 7700 ION can be synchronized to within ± 1ms of Universal Time, orwithin ± 2ms (typical) of other 7700 ION devices on the network.

'SQQYRMGEXMSRW4SVXWERH4VSXSGSPW9WIHTime synchronization signals from PEGASYS or a GPS receiver are receivedthrough the communications ports on the 7700 ION base unit and optionalXPRESS CARD. Signals can be received on the device’s COM 1 RS-232/RS-485port, the XPRESS CARD’S COM 2 or COM 3 RS-485 ports, or the XPRESS CARD’S10BaseT and 10BaseFL Ethernet ports.

An XPRESS CARD is required if time synchronization from a GPS receiver isimplemented (two communications ports are required in this configuration), andCOM1 should be used to receive time synchronization signals.

Time synchronization can be achieved using ION and DNP3.0 protocols (notethat DNP 3.0 can be used on only one XPRESS CARD port per device). GPS timesynchronization uses special protocols defined for the type of GPS receiver youare using.

'SRJMKYVMRKXLI-32XS-RXIVTVIX8MQI7]RGLVSRMÊXMSR7MKREPW

To implement PEGASYS or GPS time synchronization, use ION Designer or theMGT to configure the Clock module and the Communications or Ethernetmodule:

♦ Specify which port will receive time synchronization signals by setting theTime Sync Source setup register in the 7700 ION’s Clock module. Onlysignals received on the port specified will be used for synchronization.

♦ Specify the protocol you want to use by setting the Protocol setup register inthe 7700 ION’s Communications module (or Ethernet module) for the portthat receives the signals.

You may need to modify the “Time Sync Type” setup register if a DNP Master issending time broadcasts in local time.

If you are using PEGASYS as the source for time synchronization signals, set theCommunications or Ethernet module’s Protocol setup register to ION. If you areusing a GPS receiver as the time source, specify the receiver type in the Protocolsetup register that matches your receiver. Various GPS receivers are supportedby the 7700 ION.

This appendix provides an overview of the 7700 ION-RMxxxx Revenue Meters.

The fundamental functions of a revenue meter are to provide measurements thatare within industry-accepted limits for accuracy over a defined range ofoperating conditions, and to provide adequate protection against unauthorizedalteration of these measured quantities. International and national standardsensure industry-accepted accuracy limits. A combination of national and utility-based standards regulates protection against unauthorized quantity alteration.

-32611SHIPWTwo models of the 7700 ION-RM revenue meter are available; each model isdesignated by the certification it holds.

(MJJIVIRGIWFIX[IIR7XERHEVHERH611SHIPWThe 7700 ION-RM differs from the standard (non-revenue) 7700 ION meter:additional modules for revenue calculations and new energy output registerlabels have been added to the 7700 ION-RM firmware.

6IZIRYI1IXIV)RIVK]3YXTYX6IKMWXIV0EFIPWThe revenue and non-revenue meters differ in how they label energy flow:standard 7700 ION (non-revenue) meters use the terms “imported” and“exported” energy, 7700 ION-RM (revenue) meters use the terms “delivered”and “received” energy.

The energy output register labels of the 7700 ION-RM follow the revenuemetering terminology; the energy labels for kVAh, kVARh and kWh are differentfrom the non-revenue devices as follows:

♦ “imp” is “del” ♦ “tot” is “del+rec”

♦ “exp” is “rec” ♦ “net” is “del-rec”

For example, the 7700 ION’s output register “kVARh tot” will be “kVARhdel+rec” in the 7700 ION-RM. A complete list of output registers is given inChapter 2 for the non-revenue version of the 7700 ION.

%HHMXMSREP6IZIRYI1IXIVMRK*YRGXMSRWThere are 20 additional modules incorporated into the frameworks of the 7700ION revenue meters. Some of these modules are used in the calculation andlogging of both V2h and I2h (used for transformer and line loss compensation).The additional modules are as follows:

♦ 7 Integrator modules ♦ 4 AND/OR modules

♦ 2 External Pulse modules ♦ 1 Arithmetic module

♦ 1 Data Recorder ♦ 4 Pulser modules

♦ 1 External Boolean module

With the addition of these revenue-based modules, the overall processor powerused by the device (Diagnostic module’s Prc Pwr Used output register) isapproximately 94%.

7IGYVMX]1IGLERMWQWTo meet Government regulations and Utility security requirements, the 7700ION-RM revenue meter incorporates three types of security systems:

♦ a traditional “anti-tamper” mechanical seal on the 7700 ION base module

♦ a password-based security system that permits password protectedminimum/maximum resets (for example, Sliding Window Demand reset)

♦ a hardware-based security system that uses the RMKEY programming key

8VEHMXMSREPl%RXM8EQTIVz7IEPWThe top panel of the 7700 ION-RM model has two tabs where you can apply arevenue seal. When utilized, these lead/wire seals effectively preventunauthorized personnel from gaining access to meter internals. These seals aresupplied by the meter owner, and are installed as follows:

1. Ensure that the top panel of the 7700 ION_RM device is in place and the fourscrews are fastened.

2. Insert the wire through the hole on one of the seal tabs protruding through thetop panel.

3. Twist the wire and crimp your lead sealing tab onto the wire.

4EWW[SVH4VSXIGXIH1MR1E\6IKMWXIV6IWIXWThe 7700ION meter front panel (MGT display panel) incorporates a passwordthat must be entered in order to reset any of the minimum/maximum registervalues. The password must therefore be used to reset peak demand registervalues.

,EVH[EVIFEWIH7IGYVMX]The 7700 ION-RM revenue meter is equipped with a comprehensive securitysystem that provides protection against unauthorized alteration or tampering of“revenue-related” quantities. This security system “locks” all revenue-relatedION modules, ION links and ION setup-registers. Of particular importance is thefact that basic meter configuration parameters including volts mode (service-type), PT ratio, and CT ratio are locked. These locks are automatically enabled (atthe factory) for all 7700 ION-RM meters.

6IZIRYI1IXIV4VSKVEQQMRK/I]61/)=

The Revenue Meter Programming Key (RMKEY) is a 3”x 4” (76mm x 102mm)circuit board. When the RMKEY is inserted into the 7700 ION-RM RevenueMeter, the key disables the meter security systems to facilitate programmingprior to sealing (see “Configuring the 7700 ION-RM” below). Utility meter shoppersonnel who wish to program the meter in-house use this key. Each utilitypurchases one RMKEY (if desired users can purchase a spare key) which can beused in any 7700 ION-RM Revenue Meter.
