My project uses S7-1500 R/H and it needs to connect with an S7-1200 CPU (outside my scope) through a PN/PN coupler. This is easy when both CPUs are within the same TIA Portal project. However, these two CPUs belong to two different TIA Portal projects. Could you please show me how to use the PN/PN coupler in this case, and it would be great if there is a document or a video guide on the steps to follow.

I look forward to your help,

Thanks and Best regards.

Thank you for your recommend,

I use PN/PN coupler v4.2 for my project. But I cannot find the PN/PN X1 v4.2 like the FAQ to config for Profinet network 1.

TIA V17 only has PN/PN coupler v4.2 with both side X1 and X2 (6ES7158-3AD10-0XA0)

What should I do?
