PN Coupler COMM

I am trying to communicate Siemens S7-300 CPU to ABB AC500 via Siemens PN-PN coupler 6ES7 158-3AD01-0XA0. and I am not able to communicate. Anyone can give a suggestion?

Not much info to work with, eh ?

I dont know about ABB, but in the Siemens side you can investigate the hardware diagnostics with STEP7.
And on the PN/P coupler there will be some LEDs. What is the status of all LEDs on the S7 CPU, PN/PN coupler and the ABB CPU.

And how is the hardware setup on both sides. Can you provide some screenshots ?

Was it working and it stopped? Or are you trying to configure from scratch?

Have you assigned the Ethernet address to it?

Since you didn't mention it, do you have the profinet module for AC500? I don't think AC500 PLCs have onboard support for profinet.
