Network Settings

It is common for systems connected via the OPC Router to be installed on different computers. This is not a problem for the router. However, ensuring that the Windows configuration on the involved computers is correct is crucial. It is essential that you commission a distributed router project in collaboration with your network administrator. By the way, inray also offers project planning and commissioning as a service.

We generally recommend that you observe the following:

  • Open the required ports in the firewalls of the involved computers instead of disabling the firewall. The ports used by the OPC Router itself are listed under Network Ports; for each connected system, add the port of the target system. OPC Classic is a special case: Because DCOM dynamically negotiates the actual communication port, the computer running the OPC server requires its own rules—see Distributed OPC Servers/DCOM.
  • Ask your network administrator to enable communication between the systems involved. Special permissions are often required if the connected servers are not on the same network as the OPC Router (e.g., sending email via an external mail server).
  • Set up a user,
    • who is logged into your Windows domain
    • who has administrator rights on the computer running the OPC Router
      • under which the OPC Router service is started
    • who receives the DCOM permissions on the computer running the OPCserver receives the DCOM shares
    • who is also logged in as a user to the MS SQL or Oracle database via Windows authentication.

Permissions for Internet-based targets that the OPC Router accesses on its own—licensing, pronubes connection, Solution Gallery—are listed under “Network Requirements for Firewall and Proxy.”
