Problem with Weintek MT8051ie and 2 Siemens LOGO

[Carmelo]

I have a configuration with an MT8051ie panel that communicates with:

LOGO! 8 (master) with IP 192.168.88.98, local TSAP 10.00 and remote TSAP 2000
Datexel DAT3580 with IP 192.168.88.97

With this configuration everything works perfectly for some time!

Now I need to add another LOGO! and in my hands I have a LOGO! 7 which is perfect for use!

I load the LOGO! 7 program which will be another independent master from LOGO! 8, and I give 192.168.88.96 local TSAP 11.00 and remote TSAP 20.00 as IP address. I create the display pages but after loading everything I realize that as soon as I open the LOGO! 7 page some variables of the LOGO! 8 are reset or changed randomly.

How is it possible and how can I solve it?

In addition to the LOGO driver, you have verified that the correct LOGO version in the IP settings has been selected in the Weintek terminal.

Check that there are no active master / slave communications between the 2 PLCs.
