Hello. I have Cpu 315-2pn/dp and I have Lumberg 0970 PSL 701 DI/DO Module. I uploaded the GSD file, but I could not communicate. I think my cable connections are wrong. Can you help me?
 
The cable connection is very simple.
If there are only the 315-2PN/DP and the Lumberg device, then in the Profibus connector on both ends:
Green wire goes to A1 and red wire goes to B1.
And in both connectors the termination should be set to "ON".


The only thing that must be set up in a Profibus slave is the station no. Usually it is done by dip switches. Have you done this and does it match the setup of the slave station no in the STEP7 project ?
 
And if they are feed through connectors make sure the cable is attached to the IN terminals and not the OUT terminals.
