2.1 Display of the screensWhen SIMEAS P has been adapted to its measuring task (chapter 4) andconnected (chapter 2), the measured variables determined by the user aredisplayed on screens. The screens can be selected via

the two front buttons. Press a button once to display the

next or the previous screen. Hold the button to scroll through

the screens automatically. Equally, a fixed automatic scrolling

through the screens can beparameterized.

You scroll through screens in a loop,i.e after the last screen the first isdisplayed and vice versa.

2.2 Contents of the screens

The user must be able to read all information relevant for the measurement task ata glance.

For this purpose, the screens feature a simple and individual design. The numberof screens (max. 20), the screen types and their contents can be individuallyparameterized by the user

The following screen types are available:

2.2.1 Screen types 2 MVS digital 2 MSV digital / analog 4 MSV digital 4 MSV digital / analog Arrow diagram Harmonic U / I Min Max values Oscilloscope Sinus / rms values

2.2.6 Vector Diagram

Here the status of the system can beread a glance.

Digital and graphic display of allconnected conductorsmeasured variables: U / I / cos phi



2.2.7 Harmonics screens

Graphic display of screens withharmonics of current or voltage.

Display of all odd numbers in allconductors up to 21 harmonics.

When "ENTER" is pressed,a window appears on the right upperscreen indicating the digital values of one harmonic for all three conductors.

Via the buttons all odd harmonics up to 21 can be selected in thedisplayed window.

Hold the "ENTER" button to enter the main menu of level 2. Graphic display in % of the measured value. 100% represents the maximum

value of the first harmonic of one of the three conductors. Digital values:voltages in %, current in A.

The harmonics (5th,7th,11th,13th,17th,19th) considered important in thestandard can also be displayed individually as measured variables on themeasured values screens.

2.2.8 Min Max values

Up to 8 measured variables frommeasured variable tables (exceptenergy and metered values) can bemonitored here.

Display of the minimum value, theaverage value, and the maximum valueof a variable measured since the startof the recording.

The recording starts with the "Reset" of the Min Max values on theparameterization level or when the device is switched on.

If no time is set, the duration of the recording is indicated in hours and minutes.If the time is set, the date and the time of the recording start are indicated.

Any number of listing screens can be parameterized. Using space lines instead of measured variables provides a clearer overview of

the representation.



2.2.9 Oscilloscope

2.2.9.1 General

The oscilloscope represents a special case among the screens. Only one screenoscilloscope can be selected. The settings are made directly on the screenoscilloscope via the button Enter = Menu. Always 3 measured variables are recorded. The level height of each measured variable is accomplished automatically. Display of the measured value of each measured variable via cursor position. Generally, 10 % of the history of each recording is displayed. Only one recording is possible. When initiating a new recording, the previous

one is deleted. When triggering the oscilloscope via limit violation, the recording can also be

executed in the background. Only the first of several limit violations which triggers a recording is recorded.

Further violations are ignored. A new recording must be activated in the menuvia "OK + enable".

The total duration of a recording including the pre-fault history and the post-fault history is limited to 7040 measuring points for sinus values and 14000measuring points for rms values per measured value.

2.2.9.2 Menu

Record type Instantaneous value Rms value

Measured values 1 to 3 From measured variable table

(depending on record type)

Trigger Manual (after start-up via the front button "ENTER") Limit value 1 to 6 (Upon selection and confirmation an input window for

modifying or confirming the limit value parameters appears. As described in thechapter "Device parameterization, "Input window for limit values", hysteresis,filter time, and the connection of several measured variables can bedetermined.)

Recording time The recording time depends on the record type. For instantaneous values the setting of the recording time is fixed to 2 second. For rms values it can be adjusted < 4.0 h.

* Record type : Instantaneous value* Measured value 1 : U L1* Measured value 2 : L2* Measured value 3 : U E-N* Trigger : Manual* Length : 0 : 0 : 2

< Zoom off< Cursor off< Abortion< OK + enable< Main menu



Zoom If the zoom function is activated via "on" and confirmed, the time axis can be

changed up to the minimum or maximum variable via the buttons

Cursor If the cursor is activated via "on" and confirmed, the cursor can be moved on

the time axis by using the buttons . If the button is pressed once, thecursor moves by one position. If the button is held, the cursor movesautomatically with increasing speed.

The values of the measured variables are automatically displayed on the Yaxis for the corresponding cursor position.

Abortion Modified settings in the menu are not accepted. Back to the oscilloscope

screen.

OK + enable Modified settings in the menu are accepted and trigger the recording. Back to

the oscilloscope screen.

Main menu Here the user can access the main menu of level 2 from the oscilloscope

screen.

2.2.9.3 Characteristics of "Instantaneous value" recording

Recording time cannot be changed and is fixed to approx. 2s ( 200 ms of pre-fault history and approx. 1800ms of post-fault history). (7040 measuring pointsper measured variable).

The time axis in the screen can be changed via zoom from 60 ms to 2000 ms

Sampling points

The measuring interrupt is thus adapted to the frequency that each period issampled with 64 measuring points.

Therefore, the sampling rate is: At 50 Hz = 3.20 kHz At 60 Hz = 3.84 kHz

Trigger via limit violation:The rms value of each half wave is calculated and tested for Max/Min violations. Aviolation immediately triggers the recording.



Only the measured variables currentor voltage are available for input.The parameters hysteresis and filtertime are meaningless.

2.2.9.4 Characteristics of "Rms value" recording

3 measured variables can be selected from the measured variable table exceptenergy and metered values.

Recording time can be modified up to a maximum of 3h 59min. (approx.14000 measuring points per measured variable)

Each second one measuring point of a measured variable is saved. Pre-fault history is always 10% of the selected recording time. Time axis on the screen can be changed via the zoom function:

Note

As 10% of the recording time are always written as pre-fault history, the time forwriting the pre-fault history must expire before a new recording can be triggered.The minimum time resolution on the display is limited for the recording time by thenumber of the approx. 200 pixels. That is 1 pixel = 1s per measured value. Theshortest time period which can be displayed on the time axis is thus approx. 3 min.For recording times < 3min, only a part of the display width is used for recording.



2.2.10 Status line

The screens ( except harmonics and oscilloscope ) feature a status line whichdisplays the status of SIMEAS P.

Here, the user himself can select the internal measuring range of SIMEAS P. Up toY 400 / 690V can be connected directly without a transducer.

Caution:

The range must be determined for the setting with and without transducer. The selected measuring range must be greater than the secondary value of the

transducer! The accuracy of SIMEAS P refers to this measuring range. The determination of this range indicates the maximum range which can be

displayed on the device. The frequency measurement of SIMEAS P is initiated only when the

determined voltage is >20%. Also for "Connection: single-phase AC current" the measuring range must be

indicated as line to line voltage L-L. The L-N measuring range must bedetermined according to the conversion table.

5.1 Introduction

The following chapter contains a description of how the communicationfacilites of the SIMEAS P Power Meter ( 7KG7000-8AA ) are connected.The brief, general introduction on the topics communication andPROFIBUS is followed by chapters providing all relevant informationconcerning the PROFIBUS connection of SIMEAS P. In the annex you will find thePROFIBUS data records in detail.

5.2 General introductionPROFIBUS- DP is an open, standardized and manufacturer-independ field bussystem. PROFIBUS DP is standardized according to DIN (E) 19424 Part 3 / EN50170 and thus provides the ideal basis required for the high demands posed todata exchange in the domain of distributed peripherals and field devices. Morethan 1000 manufactures to date (date: Sept. 2000) offer more than 1500 productsand user organisations in 23 countries provide technical support for the users ofthe approx. 3 million PROFIBUS nodes installed worldwide.Further integration and connection to common automation concepts is equallyunproblematic since all major manufacturers of programmable logic controllers(PLC) offer PROFIBUS DP master modules and the systems operate nearly inrealtime due to the high transmission rates of up to 12 Mbaud.

The protocol used for the communication of the PROFIBUS nodes provides for thecommunication between the complex, democratic automation devices (masters)thus enabling each node to accomplish its communication tasks within specifiedtime intervals.Furthermore a cylic data exchange is implemented via the Profibus for thecommunication of a master with the associated simple peripherals (slaves) withsmall effort.

For this purpose, PROFIBUS relies on a hybrid control system for bus accessconsisting of a central token-passing procedure between the active bus nodes(masters) and one central master-slave procedure for data exchange betweenactive and passive bus nodes.This control system for bus access enables the following system configurations tobe implemented:

- Pure master-slave system- Pure master-master system with token passing- A system consisting of a combination of both procedures

Passive Stations, Slave Devices

Locigal Token Ring between the Master Devices

The figure depicts an example with 3 master modules and 7 slaves. The 3 masterdevices constitute a logic circle. Control of the token is accomplished by the MAC(bus access control). In the start-up phase it generates the token and controls thatonly one token is passed within the logic circle.

Each slave communicating cyclically via the PROFIBUS is assigned one class-1master. The cyclic data exchange is accomplished according to the DP standardprofile (DPV0). A class-1 master primarily fulfils automation tasks. In addition to thecyclic data exchange a class-1 master can also establish an acyclic communicationconnection to its slaves and thus utilize the expanded functions of a slave.

A class-2 master is especially appropriate to accomplish commissioning tasks,diagnostics and visualization tasks. It is connected to the PROFIBUS in addition toa class-1 master and can address slaves and exchange data via acyclic services,provided this is permitted by the slaves.

The acyclic data transmission is accomplished via DPV1. DPV 1 supplements theexisting PROFIBUS standard by several functions. Among others this enables theslave configuration to be modified during running operation and to establish anacyclic data exchange. DPV1 also enables data to be read directly from the slaveby a class-2 master although the slave still entertains a connection to a class-1master.

A suitable example is represented by the cyclic data exchange between a powermeter and the PLC as class-1 master and the simultaneous acyclic visualizatione.g. by means of the WinCC monitoring system installed on a PC with aPROFIBUS interface (class-2 master).

5.3.2 Integration via the GSD fileThe configuration of the device parameters is accomplished via a configuration toolwhich each DP standard master contains. If a SIMATC S7 is applied as master,this is the HW Config of the SIMATIC STEP7 package. If it is not a SIMATIC S7,the configuration can be performed in dependence of the master e.g. via COMPROFIBUS.If the GSD file containing the device master data of the power meter has not yetbeen installed, this file must previously be integrated into the configuration tool. Forthis purpose, you can, e.g., copy the GSD file to the subdirectory in which all GSDfiles of the configuration tool are stored and update the device library via thecorresponding menu item. All parameters are stored in the GSD file which must besent by the master during start-up of the slave.

Subsequently, select the SIMEAS P Power Meter from the device catalog, thedesired basic type and all other parameters, measured variables and addresses ofthe data transmission.

Via the GSD file the SIMEAS P Power Meter is always integrated as DP standardslave. Optionally, additional data can easily be transmitted also via DPV1 and e.g.parameters can be modified.

Measured variables in HW Config of STEP7

5.4 Cyclic data exchangeDuring cyclic data transfer each telegram transfers a specified number of userdata. For this purpose, it must be determined during the configuration of the slave(here SIMEAS P) how many and what data are exchanged cyclically between thepower meter and the PLC. Cyclic data exchange therefore represents the bestoption for transferring information which are required continuously and rapidly. Thetime interval between two values depends on the number of nodes, the datavolume and the baudrate.Subsequent modifications of the data volume during operation are not possible.Therefore, the exclusively cyclic data exchange is very well suited for acommunication that operates with a small volume of user data.



5.4.1 Basic types for the cyclic data exchangeDue to the large data volume provided by the SIMEAS P Power Meters, acompromise between the data volume and the performance on the bus had to befound. If the information volume transmitted during data exchange is too large andonly a small amount of the data can be used, the performance of the PROFIBUS isimpaired.Therefore, three basic types are available for efficient and flexible transmission.During configuration this enables the best-suited basic type and the correspondingbus configuration to be selected for the specific application case. Configuration isaccomplished by means of a PROFIBUS configuration tool such as e.g. COMPROFIBUS or HW Config of Simatic S7. The basic types are already pre-assignedand enable a fast commissioning without additional configuration /parameterization.

Selection of the basic types

Of course, configuration within one basic type can also be defined by the user.

Note: Data that is not required permanently can additionally be transmitted viaDPV1.



5.4.2 Overview of the basic typesThe following table provides an overview of the basic types including the size andthe division of the information which can be called cyclically by SIMEAS P.

5.5 Data exchange via PROFIBUS DPV1PROFIBUS DPV1 is an expansion of the PROFIBUS DP protocol. Devices forPROFIBUS DP and also for PROFIBUS DPV1 can be connected to one line. It isdownward compatible; therefore the PROFIBUS DP protocol and the PROFIBUSDPV1 protocol can run over the same line. Additional data blocks can thus betransmitted acyclically with up to 240 bytes of user data by means of applicationprograms such as STEP7 or WinCC.The PROFIBUS DPV1 protocol thus constitutes the basis for a comfortable dataexchange of e.g. parameter data, diagnostic data, control data, and test data.

The prerequisite is a DPV1-compatible class-1 master or class-2 master. Theyenable the above mentioned data to be transmitted via an additional establishedchannel.The class-2 master can even establish communication to slaves that are notconfigured and parameterized by this master and which still entertain a connectionto a class-1 master. A class-2 master is especially suitable for commissioning,diagnostics, and visualization tasks e.g. by using the program WinCC.

5.6 DiagnosticsIf the SIMEAS P Power Meter has problems during data transmission or if animportant status occurs in the power meter, it generates a high-priority diagnostictelegram. The master collects this high-priority diagnostic telegram as soon aspossible, thus enabling the user to react fast if critical states occur.

For a Simatic S7 this diagnostic telegram initiates a diagnosis alarm and the objectblock (OB82) responsible for the processing of diagnosis alarms is invoked. If theobject block is not programmed, the alarm indication is not processed and the PLCenters the Stop mode. If the object block is programmed, the alarm indication canbe evaluated and subsequent actions and indications for the user can be initiated.



5.7 Detailed protocol description

5.7.1 Introduction

A protocol for SIMEAS P (power meter) via Profibus DP V1 will be defined in thefollowing. This protocol is used for different purposes. Among others, the protocolsupports the parameterization as required by the end user, the calibration, thecollection of measured values and the final testing of the device.The individual layers required for providing the communication services accordingto the ISO-OSI reference model will be explained.

5.7.2 Standard services

Standardized services for the application layer are described which are currentlylimited to the file transfer as the sole service. The file transfer is defined in the twodirections of data transfer. From the master (controlling station) to the slave(controlled station) and vice versa. The definition is in accordance with theIEC 870-5-5 file transfer.

Description:

This file transfer is used to receive data from the slave. The master subdivides thefile into sections. Each section can be further divided into segments. If the slavehas no data to send, no SectionN_SegmentM telegram is sent and the A_EOFtelegram follows immediately after the confirmation A_File_Ready. The datarequest contains a counter number which is incremented by 1 for eachtransmission step. The counting starts at 0. When the maximum value has beenachieved, the counter number is reset to 0.

Corrupted data:If the slave detects an error in the telegrams received, it responds by sendingNACK. The master then repeats the telegram. If the slave does not send aresponse, the master repeats the request after a certain period of time (timeout).Timeouts are defined independently of each other for each telegram.

5.7.2.3 Mapping to Profibus-DPThe standard for Profibus DP does not provide a service that is directly comparableto file transfer. The nature of file transfer is the bitwise transmission of larger datavolumes upon request. This contradicts the operating principle of Profibus to agreat deal. Originally, Profibus DP performed only cyclic data transmission of aspecified length; the expansions (DPV1), however, at least enable acyclic datatransmission upon request. These are, however, restricted to a permanentlyassigned address space of 64kB. For this reason a file transfer is established bymeans of the available services. However, it cannot be assumed that this filetransfer is supported by standards-compatible application software on the masteras a standard feature. File transfer under Profibus is thus only suitable forapplication services with an optional structure (they can also be renounced) orredundant (standards-compatible support is also available).The file transfer on Profibus DP relies on acyclic data transmission (MSAC1 orMSAC2 , API=0). Competence for this service is assumed by slot 0, index 240whose assignment corresponds to the telegram structure in "Maintenance protocolASCII" (see Fehler! Verweisquelle konnte nicht gefunden werden.).The communication procedures SEND/CONFIRM or REQUEST/RESPOND of theASCII protocol are mapped to the services DDLM_Rd_Outp/ DDLM_Rd_Inp of theProfibus protocol. All requests to a slave are thus mapped by writing a data block(0.240) and the responses from the device by reading a data record (0.240).



5.7.3 Device protocol SIMEAS P (layer +)

5.7.3.1 Continuous transmission of measured data

The cyclic transmission of measured data to the master is accomplished via theProfibus service MSCY1. To enable weighing with respect to performance or busload and information needs, different sizes can be selected for data transmissionpackets. These so-called basic types define the size and the contents of requestpacket and response packet. 3 different basic types are available. They can beselected within the Profibus configuration tool.For each basic type specific information elements are defined which can constitutea part of the request packet or the response packet.

5.7.5 Parameterization

File format PROFILE

File Transfer enables data volumes to be transmitted which are flexible in theirsize. The structuring of these data volumes is not further defined. A file format isnow defined which will be used frequently in the following. It is the objective toestablish a data structure which can be expanded flexibly and which enables ahigh degree of interoperability between the software (parameterization software,evaluation software etc.) and SIMEAS P hardware of different versions. The modelfor this structure are files in the format of a Windows *.INI file (Windows 3.xProfiles).Each octet is of the data type ASCII and not "case sensitive". A file is transmittedas sections1 (SECTIONS defined by key words in square brackets []).Syntax:

The description of the information elements is accomplished sectionwise. For eachsection (SECTION) the contents and the data types used are described.Each section contains its name at the beginning. This serves as a first structuringof the information elements. The content of the section is indicated in each line bythe individual information elements in the form:Key =ValueEach line must be terminated by an end-of line-identifier CHAR(0).Data types are put in brackets . They are not transmitted as plain textbut serve as wildcard for a value whose data type is indicated by the qualifier within. Standard data types such as , etc. are explained atthe end of this paragraph. Data types in curly brackets { and } indicate thatseveral values of the data type separated by a comma can be entered.

Example: ={}become e.g. U=L1,L2.L12,L31 or I=L1,L2

Not every information element must be available in future versions of a concretedata format or information elements might be added in the future. To handle thesemodifications with the appropriate flexibility, the following is defined:An information element whose name is unknown or not supported will be ignored.

An information element for which a row with the corresponding name cannot befound, is assigned a default value if possible.

Comments can be limited by a semicolon. If a semicolon is set, the remainder ofthe line is regarded as a comment.
