CP541 To 95U-B

I am a rookie when it comes to STL. I have the 2 PLC's connected, no bus faults, but they are not talking to each other. Don't understand L2 send & receive blocks in 95U & the same in 100U . Resetting send and receive bits etc, etc.

What is your problem? Tell it in detail please. There are lots of people here who are familiar with Sinec L2 (profibus) and Siemens PLC's. We can help you if you let us. Best regards Hakan Ozevin
I guess my problem is what is my next step. I assume because the bus fault lights are not lit, I have a good connection on the bus. How do I get info from one PLC to the other? The ultimate goal is to network 8 PLC's.The network wire is installed and have all the hardware. What happened is our supplier went out of business before all the communications were set up and I'm attempting to do it myself. Thanks, [email protected]
