EDS FilesDeviceNet requires an Electronic Data Sheet (EDS) to configure a slave. AnEDS contains product specific information and is designed to makeconfiguration easier.

AiRanger Series, CraneRanger and InterRanger DPS 300The file for the SmartLinx DeviceNet card is called hms-1002.eds and islocated on a disk shipped with the card.

EnviroRanger ERS 500, Accumass BW 500.The file for the SmartLinx DeviceNet card is called hms-1003.eds and islocated on a disk shipped with the card.

Sample Code

Also on the disk shipped with the card, are some sample PLC programs forthe Allen-Bradley PLC5 and SLC500. These programs are intended as a“guide only”. Milltronics assumes no responsibilities for their application.

Set-up Procedure

The set-up procedure will vary depending on the type of equipment used.Generally do the following steps:

1. Import the Milltronics EDS file into your network configuration software.

2. In the software, configure the Milltronics instrument at the desired MACaddress.

3. Add the Milltronics instrument to the ScanList of the scanning instrument(DeviceNet master). It would be added as Polled I/O with the Rx and Tx asstated on page 15 for the product you are using.

4. Download the new configuration into the DeviceNet Scanner.

5. Configure the Milltronics instrument to the correct baud rate and MAC ID(P751, P752) and connect it to the network. Refer to the following section onSpecific Parameters.

6. Program the PLC to read and write the information from the scanner. Thisstep varies with the PLC. For example, for the PLC5, set up a block transferread and a block transfer write. Please see the support disk for examplecode.

The following parameters must be defined in the Milltronics instrument toestablish successful communication. Instructions on how to set theseparameters are found in the associated instrument manual.

Application LayerThis section describes the meanings of data read from, and written to theMilltronics instrument memory via the SmartLinx DeviceNet connection. Theoutput words (PLC master write operation) and input words (PLC masterread operation) are described in three areas within this section of themanual. For the AiRanger series of products, refer to the Data Map on page24. For the EnviroRanger series, refer to the Data Map on page 30. For theAccumass BW 500, refer to the Data Map on page 36.

Note:Parameter P999 (Master Reset) is not accessible via the SmartLinxinterface on Level products.

Parameter IndexesConfiguration and operation of Milltronics instruments is controlled byparameters that are entered into the instrument. Most parameters used onMilltronics instruments are indexed. Indexing allows a parameter to relate tomore than one input or output. For example, many parameters are indexed bymeasurement point while others are indexed by relay output or discrete input.

An index that relates to an input or output is called a Primary Index.

Examples of primary indexes are:P111[3] = 52 means:P111 (Relay Control Function) for relay 3 is set to value 52

Sometimes a parameter requires a second index to allow for multiple valueson an indexed input or output. For example a measurement point whichcalculates a reading on volume can require characterization breakpoints.These breakpoints are given on a secondary index (the primary index relatesto the transducer input).

On some older Milltronics products the primary index is called a point.

52


Ap

plic

atio

n L

ayer

An index that relates to a previously indexed parameter is called a secondaryindex.

Examples of secondary indexes are:P054[1,5] = 1.6m means:P054 (Breakpoint Levels) for breakpoint 5 on transducer 1 is set to 1.6m

The way that indexes are handled in the memory map depends on the dataaccess method used.

On some older Milltronics products the secondary index is called a mark.

Data Access MethodsThere are three different methods used as shown in the Data Maps (seepages 24, 30,and 36) to give access to the SmartLinx module parametertable. They are:

• Direct Access – changes the operating mode, read status or themeasurement point value

• Multiple Parameter Access (MPA) - allows you to monitor a singleparameter on index points 1 to 10. Using these words does not allow thechanging of parameter values (For level products only).

• Single Parameter Access (SPA) - any value in the Milltronics product can beread or written.

The use of these methods are detailed in the following sections.

1.6m

Direct Access

Certain values are mapped directly into words. These words can bemonitored continuously.

Multiple Parameter Access (MPA)

This is a hand-shaking method where the user writes the parameter number,secondary index, decimal place, and format. Then, the instrument providesthe values of the requested parameter for the primary index 1 to 10.

Note:In Milltronics’ products, the memory is arranged as Parameter number,Primary Index, Secondary Index.

Using Multiple Parameter Access (MPA)MPA allows you to monitor a single parameter on index points 1 to 10. Usingthese words does not allow the changing of parameter values.

1. In the output table of the PLC (Write Block) write the values for theparameter number, secondary Index, decimal place and format in the correctlocation.

2. Monitor the Input table of the PLC (Read Block), and watch for the valuesyou wrote to appear in the appropriate locations of the read block, then go toStep 3.

3. Read the requested values in the appropriate location of the Read Block.These values are continuously updated. Continue reading from these wordsuntil values for another parameter are required, then go back to step 1.

Note:MPA values are only updated in Run mode (word 12 = 0).

Parameter Indexing with MPAPrimary IndexThe primary index is implicit in the memory address. MPA values arereturned through 10 words of the read block (see pages 27 and 33).

Secondary IndexThe secondary index is nearly always left at zero. See the manual for theMilltronics instrument for information on parameters which require asecondary index.

Single Parameter Access (SPA)

This is a hand-shaking method where the PLC specifies:

• parameter number• primary index• secondary index• decimal place• format• read/write flag• value

With this method, any value in the Milltronics product can be read or written.

Using Single Parameter Access (SPA)SPA, allows continuous monitoring or demand programming of a parameter.

Reading a Parameter1. Set the Read/Write flag in the output table (Write Block) to 0, “read”.

2. Write the Parameter Number, Primary Index, Secondary Index, DecimalPlace and Format in the correct locations.

NoteIf there is no secondary index, then place a 0 in this location.

3. Monitor the Input table of the PLC (Read Block) and watch for the values youwrote to appear in the appropriate locations, then go to Step 4.

4. Read the requested parameter value in the Input table (Read Block). Thesevalues are continuously updated. Continue reading from these words untilvalues for other parameters are required. At that time, go back to step 1.

Writing a Parameter1. Set the Read/Write flag in the output table (Write Block) to 0, “read”.

2. Write the Parameter Number, Primary Index, Secondary Index, DecimalPlace and Format in the correct locations.

3. Write the new value of the parameter into the correct location of the outputmemory (Write Block)

4. Verify the unit is in program mode (not needed for BW500). For Level see bit10 of status word in Read Block.

5. If it is not in program mode, write a 1 to the operating mode word in theoutput memory (Write Block). Please note that this will only work if the wordis already a 0 (ie. it only works as a transition).

6. Set the Read / Write flag in the output table (Write Block) to a 1 “write”.

7. Monitor the Input table of the PLC (read block) and watch for the values youwrote to appear in the appropriate locations.

8. Set Read / Write flag back to 0.

9. Place unit in Run mode.

Note (does not apply to Accumass BW-500):Parameters can only be written in Program mode (word 12 = 1). If the hostinstrument is still in Run mode then any written values are ignored.

Word 1: Parameter Number, MPASpecifies the parameter number for the returned values in words 11 to 20.See Read Block on page 27.

Word 2: Parameter Secondary Index, MPASpecifies the secondary index for the parameter specified by word 1. Thisword is ignored for parameters that do not use multiple indexes. SeeParameter Indexes on page 19 for more information.

Note:The Primary Index is implicit in the word location where word 11 = index 1and word 20 = index 10.

Word 3: Decimal Place, MPASpecifies the number of decimal places to shift the returned values. Thisaffects words 11 to 20.

Positive values indicate that the decimal place shifts to the left.

i.e. A “1” means that all returned values have the decimal place shifted 1space to the left and a returned value of 5,213 is interpreted as 521.3.

Negative values indicate that the decimal place shifts to the right.

i.e. If this word is “-1”, a returned value of 5,213 is interpreted as 52,130.

To write a value, ensure word 11 = 1 and word 12 =1.

See also Data Types on page 44.

Word 9: Decimal Place, SPAThis word specifies the number of decimal places for the value in word 8,and also for the parameter value returned in word 28.


i.e. A 1 means that all returned values have the decimal place shifted 1space to the left and a returned value of 5,213 is interpreted as 521.3.


i.e. If this word is “-1”, a returned value of 5,213 is interpreted as52,130.Word 10: Format, SPA

This word sets the format for the value in word 8, and also for the parametervalue returned in word 28.


Word 11: Read/Write Flag, SPAThis word instructs the read/write application of word 8.

0 = read parameter as described by words 5, 6, 7, 9 and 10; word 8 ignored1 = set parameter to the value described by words 5 to 10

Word 12: Operating Mode, SPAThis word sets the operating mode of the Milltronics SmartLinx instrument.

The operating mode can get out of sync if the remote instrument resets backto run mode locally. This can happen due to a timeout or through localprogramming. The mode is always reported correctly through the Readblock. See bit 10 of Word 0: Instrument Status on page 27.

Word 8: Value, SPAThis word contains the value written to the specified parameter and index.The format of this word is specified by words 9 to 10.

To write a value, ensure word 11 = 1 and word 12 =1. See also Data Typeson page 44.

Word 9: Decimal Place, SPAThis word specifies the number of decimal places for the value in word 8,and also for the parameter value returned in word 38.





Word 10: Format, SPAThis word sets the format for the value in word 8.


Word 11: Read/Write Flag, SPAThis word instructs the read/write application of word 8.

0 = read parameter as described by words 5, 6, 7, 9 and 10; word 8 ignored1 = set parameter to the value described by words 5 to 10

Word 12: Operating Mode, SPAThis word sets the operating mode of the Milltronics SmartLinx instrument.

The operating mode can get out of sync if the remote instrument resets backto run mode locally. This can happen due to a timeout or through localprogramming. The mode is always reported correctly through the Readblock. See bit 10 of Word 0: Instrument Status on page 33.

To reset the instrument to program mode you must write “0” to put theSmartLinx module back in sync with the instrument and then write “1” to setthe instrument to program mode.

0 = run mode1 = program mode

Data TypesThe Milltronics SmartLinx instrument parameters take on many values invarious formats, as discussed in the Milltronics SmartLinx instrumentmanual. For the convenience of the programmer, those values are convertedto and from 16-bit integer numbers, since those are easily handled by mostPLCs.

Integer

Level ProductsInteger parameter values are by far the most common. For example,parameter P920 (Reading) returns a number representing the currentreading (either level or volume, depending on the Milltronics SmartLinxinstrument configuration).

Numeric values may be requested or set in units or percent of span, andmay be specified with a number of decimal places.

Numeric values must be in the range -20,000 to be +20,000 to be valid. If aparameter is requested and its value is more than +20,000, the number32,767 is returned; if it is less than -20,000, the number -32,768 is returned.If this happens, increase the number of decimal places for that parameter.

If a parameter cannot be expressed in terms of percent (e.g. span), or hasno meaningful value, the special number 22,222 is returned. Try requestingthe parameter in units, or refer to the Milltronics SmartLinx instrumentmanual to understand the format and use of the requested parameter.

Mass Dynamics ProductsIntegers used on the Mass Dynamics products can have any valid value. So,the entire range from -32,768 to 32,767 or 0 to 65,535 is available and novalues are used as error conditions.

Bit Values

Bits are packed into registers in groups of 16 bits (1 word). In this manualbits are numbered from 00 to 15, with bit 00 referring to the least significantbit and bit 15 referring to the most significant bit.

Unsigned Double Precision Integer (UINT32)

Note:Used for Mass Dynamics products only.

Large numbers are put into unsigned 32-bit integers. By default they are setup so that the first word (register) is the most significant word (MSW) and thesecond word (register) is the least significant word (LSW) depending on thesetting of the word order bit.

For example, when reading words 7 and 8 on the Mass Dynamics block(Total 1), the 32 bits would look like the following:

word 7 word 815 MSB 0 15 LSB 031 32-bit integer value (UINT32) 0

The whole is read as a 32-bit integer.

Split Values

Note:Used for Level products only

Certain parameters are actually a pair of numbers separated by a colon, inthe format xx:yy.

One example is P807, Transducer Noise, where:xx = the average noise value in dB.yy = the peak noise in dB.

The number which corresponds to xx:yy, either for reading or setting aparameter, is determined by the following formula:

For storing to the Milltronics device:value= (xx + 128) x 256 + (yy + 128)

For reading from the Milltronics device:xx = (value / 256) – 128yy = (value % 256) – 128

Where:% is the modulus operator.The modulus can be computed by following these steps:value1 = value / 256value2 = remainder of value1

value3 = value2 x 256yy = value3 - 128

It may simplify programming to notice:xx = (most significant byte of value) – 128yy = (least significant byte of value) – 128

Text Messages

Note:Used for Level products only

If a Milltronics device parameter returns a text message, that message isconverted to an integer and provided in the register. The numbers are shownin the table below:

Troubleshooting

GenerallyIn all cases, first check that the SmartLinx module has passed its on-goingbuilt-in self test (Milltronics SmartLinx instrument parameter P790). Theresult should be “pass”.

If “fail” is indicated, either the module is defective, or the module connectoron the Milltronics SmartLinx instrument is defective.

If “err1” is indicated, the Milltronics software doesn’t recognize the installedmodule. Please contact Milltronics or your distributor for instructions and/orupgraded Milltronics SmartLinx instrument software.

Make sure the Milltronics instrument is set to a unique address, and does notconflict with any other slave(s) on the bus.

Check the configuration of the scanning master, and make sure it isfunctioning properly.

If an AiRanger is being used, check P795 to make sure that it is equal to 24(DeviceNet module). If this parameter is showing any other number then youhave the wrong SmartLinx card.

Specifically

1. The card passes the built in self test, but will not connect to thenetwork.

• Check to make sure P751, P752 are set correctly and that you do nothave another instrument on the LAN with the same MAC ID.

• Check to make sure all 8 DIP switches are set correctly.

• Check the wiring to the card (or terminal strips)

2. The lights on the card indicate that it is OK and communicating, but Icannot see any data in the PLC.

• When you configured your master, did you map the data into the M files(AB only) and did you add code to the PLC you access then.

• Some Device net scanners have a control word where you can place thescanner in Ideal Mode. Check that your scanner is in Run mode.
