Hi Smiffy,

I have a system of two PLC, S7-317PN/DP + CP343-1 and S7-416 + CP441-1 ISO

please help me regarding ISO communication:

1. Can I use BSEND and BRCV if Iuse ISO transport connection?

    -> problem is that I cannot simulate PLC comunnication with AG_SEND annd AG_RECEIVE

    -> is there a way in PLCSIM to simulate ISO communication between two PLCs?

2. We have sucessfully simulated two PLCS S7-416 + CP441-1 over S7 connection (TCP/IP)

    -> PLCs are in multicomputing mode on same rack and TCP/IP communication is working in PLCSIM

Best regards

Nikola

Split from AG_SEND - AG_RECV - Error 8093H & 80D2H with PLCSIM.

I think your problem is discussed in this support article with a sample program provided:
