Hi everyone,

I'm using CPU 1512SP-1 PN V3.1 with TIA portal 19 upd 2 in VMWare workstation v15.5.7
I'm trying to use previous function we have to communicate with modbus tcp/ip

I'm using MB_Client v5.2 and RADZIO modbus master simulation.

First I got constant 7002 status, but after I disabled the firewall of the VM I started to get status changing from 7001 to 80C5 

Does anyone face something similar and might suggest a solution?

Thanks

Hello DoronH!

It seems that the connection is terminated by the other device you are trying to communicate with. It's not much, but at least you can focus on looking for why the other computer closes the connection. I attach the manual where you can find the information (page 10903).

I hope it helps! 🍀

Hello,

I see the problem probbaly here:

I'm using MB_Client v5.2 and RADZIO modbus master simulation.

From very basic description as is, it is clear that connection can't be established between 2 same role devices.

Thank Ivan, you are right.

I got confused with the server-client, master-slave terminology.
