I was trying to install gsd file for "DC303 remote I/Os" from "Smar.com", but it gives me this message:

- the file "Smar0dca.gsd" contains syntax errors.

I've contact Smar support team and they confirm that the gsd file should works fine.

I use Step7 V5.5 SP2 HF4, and i tried with another PC station with Step7 V5.5 SP3 but it gives the same message.

please see the gsd file in the attachment.

Sorry, but the GSD file attached to this post is not conform to the GSD Specification. Starting with line 159, in the module descriptions, the Module_Reference (a unique number for each module) is missing. This is mandatory starting with GSD_Revision 3 (which this GSD claims to conform to in line 11).

Thanks for the information, I have informed them about it and they send me another GSD file "attached". and I could added it to HW, but it still unable to connected to the PLC .

I am not sure if this file is also not conform to the specification  .

pls I need any idea how to make this device communicate.

Hello,

pls think, we don't know nothing about your Master system type, what is it? Can you pls give us full order number? What exact other I/O modules you have attached to that Slave device? Without this infos we can't help you.

Update: GSD file looks ok, but I see some not correct infos there defined, simply not Pro device support probably. Functionality is question...

Thanks Duris, and sorry for the lack of information, but let me introduce our system:

It is S7-400 with CPU "6ES7-407-0KR00-0AA0", and DP/PA Coupler IM153 "6ES7 153-2BA82-0XB0" connected on Profibus DP with transmission rate 1.5 Mbps coupling with profibus PA with 45.45 Kbps transmission rate.

We have two devices connected to profibus PA line: Endress & Hauser Level Transmitter "FMU40",

and Smar remote I/O "DC303".

I could connect many instruments to that network and have them communicating online except the Smar DC303 unit, I have tried all the ways to make it online but no success.

you can find attached the steps that I toke to connect to the DC303 unit.

Best Regards
