Modbus TCP HW C300 - MarkVI

Dear All,
I have a problem with TCP modbus.
The Honeywell PKS is the Modbus master and the MarkVI should be the salve.

We tried all different commands in the modbus master block without success.

The devices can see each other. So in the Master Block I can see as Connection Status: Connected, after few sec. its failed.

The error is "Socket Err".

I hope someone used this before and know how to fix.

Thanks!
 
Is this something which has worked previously in the past, but recently stopped working?

If so, what was done to the HMI just prior to the point at which it stopped working?

If this is something you are trying to implement for the first time on this unit, you'll need to provide all the configuration information for the Master and the Slave, as well as telling us which IP network the DCS is on.
