Network configuration

It is common, that the systems connected by the OPC Router are not installed on the same computer. This isn´t a problem for the router. However vulnerable to errors is the correct Windows configuration of the computers involved. Start a distributed router project in any case together with your network administrator. Projecting and starting your system is by the way also a service of inray.

Basically we recommend to notice following:

  • Deactivate the Windows firewalls of the computers involved. Especially, if OPC server and OPC Router run on different computers using the firewall is not possible just like that, because of the dynamic port placing with DCOM. If deactivating the firewalls isn´t an option at all, please contact inray.
  • Ask your network administrator to allow the communication between the systems involved. Often there are special approvals needed, if the linked server are not within the same network as the OPC Router. (e. g. sending email over an external mail server).
  • Create a user,
    • who is logged in to your Windows domain
    • who has administration rights on the computer with the OPC Router
    • under whom the OPC Router service is started
    • who gains the DCOM approvals on the computer with the OPC server
    • who is also logged in over the Windows authentification as user on the MS SQL or Oracle.
