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?
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 ?
