ScodeS Posts: 15 Rating: (1)	I have have a problem with the above configuration. I get the following error in the Module Info/Slave DP Diag.of the Slave - DP Slave not ready yet for data exchange, - Diff config data - Watchdog Activated and in the Module Info/General - Module configured, but not available - Preset/Actual mismatch. I know that my comms is OK, because I can see the slave in Accessible Nodes. I suspect that I have GSD file problems (but my supplier says it is OK). I have tested with a different DP Slave device (Danfoss VFD) and works OK. Any thoughts ? Thanks in advance.

Hello ScodeS first of all I have to say "well done" for checking the Diag info and provding the info here. What the above bold tells me is thatthe I/O's configuration of theDP Slave in Step 7's HWconfig does NOT match the physical "make up" of the DP Slave (and the DP Slave as such rejects the I/Oconfiguration from the Master and will not enter data exchange). An example on how to get thiskind of message is this: You physicallyplugged together an ET200M station with one 32 channel DI module in Slot "4" and one 32 channel DQ modulein Slot "5". In Step7 HWconfig you do however configure the DI module for slot "5"and the DQ module for Slot "4"(or configure a16 channelmodule, orconfigure only one module, etc. etc.) Please check the above and make sure your Step7 configurationmatches that of the DP Slave. I hope this helps (andif it doesn'tplease post the DP Slaves GSD file here together with your Step 7 project).

How could i configure the DP Slave to make it able to cyclical data exchange? Thanks a lot, BR:f Hi fulcrum, can you add your configuration here. Step 7 Project, GSD File and the configuration of your Slave. If you have exactly the same error message your network cable is ok, because the slave is reachable. your PROFIBUS adress is also OK and reachable. So you have onlyaconfiguration error in Step 7.
