Dear All,

my configuration :

Simotion D445 V4.4

ET200SP 1510SPF-i PN

Scout V4.5 and TIAV14

I try the basic safety function with F-proxy in the Simottion using the LDrvSafe V1.2 in the FCPU.

I followed the document App. example 50207350.

But still i have constantly communication error on the Sinamics side.

Do You have any advice about this issue?

Best regards

Claude

Thank You for answering,

I try to attach the different print screen I made.

Meanwhile, I changed the address to 71 but without any aprovement.

It seems i can only send one attachment at a time

The communication warning comes and goes. It doesn't stay constantly.

I didn't implement the topology between both CPU. If I do so, there are some communication problems with the FCPU and the linked islands.

Is the topology mandatory? There is no comment about it in the example.

Best regards

Topology seems to be mandatory, so I activate it and suppress the switch (direct link). But it didn't solve my problem.

Then I changed from basic to extended.

Now it's working fine!
