CIMPLICITY and OPC Server Nodes' DCOM Setup

Important: DCOM settings for the OPC Server must be set up properly for the system to work as required. This includes setting up the OPC Server to allow access by the OPC Client, as well as impose restrictions consistent with your site's security guidelines and practices.

When the OPC Server is located on a different computer from CIMPLICITY, it is essential that the network be operating within its designed capacity and that it be free of anomalous behavior in order for the OPC Communication to be reliable with good performance. This recommendation is not specific to CIMPLICITY. This suggestion is true for any application that uses DCOM.

You will need to be familiar with Microsoft's DCOMCNFG utility in order to configure the DCOM settings.
