Dear All,

I am having CPU315-2DP plc with CP343-1 lean  with 3 system and main line PLC CPU414-3dp with CP443-1.

I want to take  3 S7300  CPU data to S7400 system over ethernet . Is it possible?

S7 connection is not possible due to i am having CP343-1 lean.

Pls suggest any othe communication method over ethernet.

Thanks,

Hi, 

You could use this manual as guidance to find the easiest way to solve your communication issue:

CPU-CPU Communication with SIMATIC Controllers

Maybe you could pay close attention to chapter "21.4.3 S7-300 / S7-400".

I hope I could help.

Hi,

I would do a TCP communicaton with AG_SEND / AG_RECV in the S7-300 and same with S7-400 (use AGL_SEND, AGL_RCV).

 This is the only thing that can be done for Ethernet TCP protocol.
