S7300 <-> S7400 con via CP's.
Local partner does not support S7 connections, that"s the message I get when I try to add an S7 connection on a 6ES7 316-2AG00-0AB0 v1.1 CPU.
So now I builded the communication on an other way: 'ISO on TCP':

PUT and GET were replaced by AG_Lsend in the 400 CPU and AG_Recv in the 300 CPU. This works, but I do get errors on the LSend function... it sends several times without error and every... let's say 5 sends ... an error occurs. The data is transferred, so the sending from 400 to 300 CPU works, I'm just wondering why it gives errors on the LSend function.
Questions:
- Why is an S7 connection not supported in the 316 CPU ?
- The LSend errors, what could be the cause ?
Thanks,
Combo
