Siemens Profibus IM Module

Hi All,

can anyone tell me how i can display the comms status of a Siemens Profbus DP IM module connected to a DV Profibus card, i wish to use this on a graphic to let our operators know if the IM has failed?

  Gary,
  I have used a CND block to check if one of the DST values from IM 153-2 cards has "/STATUS = "Pic Device Error" to see if the IM is communicating with DeltaV (e.g. 123FIT456/STATUS = "Pic Device Error";).
  You could also pull in /STATUS of individual devices by using Object Type = Diagnostic Parameters when browing for an external reference.
  For something more detailed about the cards and channels you can also read in the IM diagnostic array and parse out its data (search for /&PDT1/DIAGMSG in Books Online but the array details are not well documented in the IM Siemens manual and I ended up using some trial and error to confirm how to detect bad status.

  Hi rob, I went to try your suggestion of changing the object type = diagnostic parameters to locate what i needed but regardless of if the comms are good or bad the value remains at 128 all of the time, back to the drawing board i think.

  Which GSD file are you using in the Profibus Master configuration? Which model of IM module are you using?

  I use Profibus quite a bit. If you have the 6ES7151 1AA02-0AB0 you will need the SIEM 806A GSD file in your hardware directory i use the .gse,
  gse is the English GSD File that i use.

  Just a note: DeltaV only support DPV0. I have not been following this discuss closely but from the above comment from GaryL, this device seems like it is trying to communicate using DPV1 and this might be the reason why you are not getting actual data as you expected.

  Gary,

  Are you looking at "/STATUS" or "/ST"? In my application (admittedly nearly 10 years ago) I used "/STATUS" which gave me a string rather than a value. The screenshot is for an ET200M rack with 4 cards (first 3 slots are the empty dummy slots it required.

  To use a Profibus DPV1 slave with a Profibus DPV0 master, it's necessary to disable DPV1 functionality in the slave. Otherwise, the DP-V1 slave will send DPV1 data (diagnostics and status information) that the master will not know how to handle. This would generate different error messages depending upon the master employed.

  Hi can you please advise how I can turn this off, I wasn't the engineer who installed these gsd files so i didn't realise that we should have been using DPV0, would it be better if i replace the drive with the correct gsd or just disable the DPV1 data?

  I currently do not have access to an EPM PB Master, but the procedure should be similar in any control system. I'll use a Prosoft PB DP Master as an example:

  

  This is the hardware configuration of the PB segment. You can see the DP Master and an ET200 slave. Open the properties window of the slave. Three tabs should be available: Common, Parameter assignment and DPV1

  Go to the DPV1 tab.

  

  by default, ET200's head station (IM153-2....) is configured as a DPV1 slave.

  

  Uncheck the DPV1 option, click Ok. You are done.

  Of course, you must download the new HW config to the DP master and restart it to see the changes.

  In the Parameter assignment tab, you can enable or disable some diagnostics parameters and data formats if you need.

  

  Hope this info helps you solve your problem.

  Regards

  One additional piece of advice: do not try to edit the GSD file manually. Each modification done via the HW configuration software has effects across the whole GSD file.

  I don't have access to the ProSoft software only the DV explorer which gives me the options shown in your second screen shot (My settings are as per yours), I am unable to find a place to turn off the DPV1 settings as you first screen shot shows, I cant include a screen shot as I don't know how to...
  
  i am wondering if there is no option to switch off the DPV1.
