Split from Communicate a S400 PLC (step 7 v5.5) with a S1500 (tia portal v13).

So a couple of CPU-CPU communication scenarios. Can someone recommend communication blocks? Lets say a lot of data is to be quickly transfered.

1. S7-400H <-> S7-1500

2. S7-400H <-> S7-1500H

3. S7-400H <-> S7-1500R

4. S7-1500H <-> S7-1500

5. S7-1500R <-> S7-1500

6. S7-1500H <-> S7-1500F

For all cases using either integrated PN-ports or via external communications processor CP443/CP1543.

I guess in most cases S7-connection + PUT/GET blocks are possible. In 1500R/H cases the system IP is used as communication IP.

Can fault-tolerant S7- connections be used for 400H <-> 1500H?

Can the PUT/GET blocks only be on programmed to the H-side if the partner is a single -PLC?

Can all be done in different PLC-projects using unspecified partner in communication setup?

And how about failsafe:

7. S7-400FH <-> S7-400F.

8. S7-400FH <-> S7-1500F.

Hello Everybody,

S7-1500H communication with other CPU's is not well documented. It could be intersting to have some programs examples with all cases identified in this post !
