I explane below my problem for the OPC server:

I have two servers, for each one, are installed two OPC server, the Simatic Net and ABB, this because the DCS ABB, monitor and control some PLC S7 through the OPC.

In my opinion the first problem is that two OPC should not reside in the same machine, is this rigth?

But the real problem is that every 20 days the OPC Siemens stops, and the PC need to restart.

My question is:

Can I monitor the OPC for to understand the reason of the stop?

Thanks for all
