Open Platform Communications (OPC) client process

The Open Platform Communications (OPC) client process facilitates communication between the AVEVA Enterprise SCADA host and the OPCserver.

The OPC Client process allows Omnicomm to create a connection between itself and the OPC Client process by using a listen port. Listen ports on the OPC Client process are configurable. Each connection is created through the listen port, which acts as a stand-alone OPC Client process.

There are two types of OPC Clients, a 64-bit and a 32-bit. Some OPC Servers, such as RSLinX Classic, require a 32-bit client in order to work properly. Both types of clients are installed on 64-bit platforms using OPC Client media. On 32-bit platforms, only the 32-bit client will be installed.

Note: The OPC Client process should run as a window service, on the same computer as the OPC server.
