And I want to connect all 3 panels to 1 S7-200 PLC with Ethernet module. My question is that possible, and if the answer is yes what is the maximum number of "client" Ethernet connection to one S7-200 PLC. If you have documentation about this case, I will be more than greatfull. Regards. Tomy.

Tomy. Can you confirm on each moment only one is active? Means if you disconnect the Nr.1 and connect Nr.2 - number 2 is OK?

And above mentioned FAQ is only valid for Siemens panels. But even I couldn't to find confirmation of this also. Anyway, what brand are OP panels? In order to try to find some confirmation if someone made this kind of communication. Meanwhile you could try to reduce panel's projects to content only one tag to see them behavior after. Best regards, Hristo Mihalev Tomy Master I panels that i am using is from WEINTEK Taiwan (MT8070i), by the way it had worked with S7-1200. Regards. According to the info which I found seems this type of panel could works only with one partner (S7-300 or S7-200). At least this is true for establishing MPI connection with the same partners. I suggest you to send request to Weintek Labs., Inc. Best regards, Hristo Mihalev
