I have a system that has 2 OPC servers on it. One Sartorius OPC server and the other is Kepware. When I try to attach to the opc server via Pi OPC Client, it cannot find an OPC server on the machine.
The firewall is turned off, it can be pinged, but the error "Cannot find OPC Server on (IP Address) remains.
Any one ever seen this issue before? What was your solution?
