To allow a client to use a COM object on another computer, the properties of the COM object must be configured on the client and on the remote computer.

You configure DCOM and the required COM objects using the Windows system program dcomcnfg.

The following chapter contains information on configuring the client computer and the configuring the computer with the OPC Server. This chapter describes the situation in which exactly one client connects to an OPC server running on a different computer. If you want to use more than one OPC server from a client, please refer to the DCOM documentation.
