The OMRONFINS Communication Driver (referred to as the Communication Driver through the remainder of this user’s guide) is a Microsoft® Windows® application program that acts as a communications protocol server. This Communication Driver is hosted by the OI Server Manager, a Microsoft Management Console (MMC) snap-in, which is part of the Operations Control Management Console (OCMC) suite of utilities.

This Communication Driver allows other Windows application programs access to data in PLCs (also referred to as devices) attached to an Ethernet network. The server can operate in either stand-alone mode or connect with any OPC, DDE, or SuiteLink compliant client application.

This document describes the OMRONFINS Communication Driver, and the device and protocol environment in which it works. It includes application-level and bus-level communications protocols, item naming conventions, and Communication Driver features.
