Studio 5000 Logix Designer

[id176293]

We recently obtained a new Vendor ID (VID) Number from ODVA, 1477 for the purposes of developing an EtherNet/IP scanner device.  When we try to use that number with the Allen-Bradley PLC & Studio 5000 Logix Designer, our data type REAL's are showing up in Studio 5000 as SINT's.  We have seen this mangling of data types before when using the Omron VID, 47 with the same Allen-Bradley PLC/EIP Scanner.  The data types are being misinterpreted, or mangled from REAL to SINT, e.g. the *.eds file defines 32 REALs for Input and 32 REALs for Output, but within Studio 5000 we see 128 SINTs each for Input and Output.

It is as though the Allen-Bradley/Studio 5000 database does not have our Vendor ID.  When I change the *.eds file, Vendor ID Number from #1477 to #1 then we see the *.eds file being properly read and interpreted, e.g. 32 REALs for Input and Output show up as 32 REALs each.  Does anyone know what file we need to modify in Studio 5000 ???  We want to add our Vendor ID #1477 to that file.

Hardware:

• EIP Scanner: Allen-Bradley Compact Logix L18ERM
• EIP Adapter: Delta Tau Power PMAC Motion Controller (EIP OpeNer Stack)

Thanks in advance!

Neat challenge !

Can you post the EDS file itself ?    Are you using EZ-EDS, or some other verifier ?

Have you tried this with any other version of Studio 5000 other than v29 ?

My guess, and it's only a guess, is that A-B left themselves some looser rules when the VID=1 that allow some older or not-quite-compliant EDS files to work correctly because Studio 5000 can internally compensate for them.  But I'm reasonably confident there is a syntactic fix.

We are using EZ-EDS.  We have tried v28 and v29 of Studio 5000.  Please take a look at the attached *.eds file.  I would very much like to implement said syntax fix...

Thank you.
