Modbus TCP/IP communication between a KTP400 BASIC PN

Hello,

I have a Modbus TCP communication problem on a basic panel, when simulating through a portal or starting it from my HMI, I have the problem that the connection is interrupted, but this happens if I use a basic panel, I did the test with a comfort panel and I had no communication problems.

Hello AutoGen_6220189

I saw in your screenshot you are using a SIWAREX

check this FAQ there is an example also with a Basic Panel:
