Hello,

I'm working on data collecting from 300/400 CPU systems.

CPU system data can be collected with SFC51 but problem is modules in DP slave.

All CPU in out system uses profibus DP to connect CPU and IM module.

Is it possible to collect data from DP slave like firmware version or FS of AI module?

If it is possible, please let me know how to do that

Best regards,

Jay

 Thank you for you reply.

I already tried with SSL-ID W#16#00B4 and W#16#0111 but, I only got only status of it.

Could you tell me which SSL-ID and INDEX should I use for those information?

Best regards,

Jay

Hi,

yes, you can use SFC51 to read Firmware of DPSlaves. Please check these FAQs:

How is a DP slave's diagnostic data read out with SFC 51 "RDSYSST" (with CP443-5 extended as a DP master)?

 The SSL-IDs you will find in chapter 33 of this manual:

System Software for S7-300/400 System and Standard Functions

Hello,

Could you let me know with more information?

Diagnostic with bits and bytes are fine but get information from each module? I think I tried all I know.

Could you help me with SSL-ID and Index?

If anyone can help me, please let me know
