TCP/IP communication with the Siemens CP343-1 Lean, SF light on

[hprosjplc]

Thanks once again. We now have connection and it works fine. Athough, it only works with ONLY the CP343 in the rail. When i add the serial module it won`t function at all. The SF og BF light (can`t quite remember is on on the CPU). I use old blocks that i know functions with the serial module.

Any ideas? Use of the same memory space? Everything else seems ok.

You can investigate the diagnostics buffer of both CPU and CPs, we cannot do that for you.
