Dear Guys

I know not whether this topic is conference " DC Converters Simoreg " or Step7, well let´s go

I have an application where the Simoreg 6RA70 has the status word 2 bit18=1, I can to see this through parameter r653.

However, on CLP S7300 the status word bit 18 = 0

this application use Simoreg 6RA70 + S7300; communication Profibus.

Please, do you have any ideia what may be going on ?

Thanks

Hello KSN

Yes, the communication between Simoreg and PLC is okay; other looks like words are okay, as well.

I have other Simoreg on same net, they are working fine.

I didn´t understand that question:

"May be you need to swap bytes in PLC in status word 2?"

The status word 2 is from Simoreg, I need read this information exactly as in Simoreg.

 Hello,

KSn mean to suggest, please check your PLC logic & the word which records STATUS WORD 2 from drive, in this word you need to swap bytes.

BTW, how data is communicated, i.e. cyclic or acyclic? Can you attach your PLC project here? 

Hello,

the solution was swap the CPB board.

Everything worked
