From the developer:
The server allows supervising device processes (watchdog) and provides the operator with the CPU load data as an OPC variable. In addition it shows the CPU load of the host computer.
The server sends ICMP (ping) or SNMP-requests to the supervising hosts, and presents these as an OPC-item. Or it supervises cyclical processes on the host to check for program errors.
OPC-Server as a gateway from your automation system to an ethernet network.
