Hi guys,

I have a Siemesn CPU 315 and ABB 800M with some I/O modules. I want to connect these two PLCs together. I would appreciate if you could help me how to do that.

Thank you in advance.

 Hello Dave,

Please specify exactly what type is your CPU and ABB (Profibus/Profinet) and your Software (STEP 7 Classic (e.g. V5.5) or STEP 7 Tia Portal).

More information you give to us, then better you will be helped

I found this but S7 400 but S7 300 is similar:
