SCADA setting Wonderware InTouch(FSGateway)

This page is an introduction for setting when OPC Server is used with FactorySuite Gateway in "InTouch" of Wonderware. FS Gateway was released as new gateway software that replaced OPCLink in 2004. It is a utility that converts four protocols (OPC/DDE/SuiteLink/MX) mutually, and operates as a universal protocol converter. We are unable to answer details concerning the setting of SCADA, so please make inquiries to the SCADA vendor or the sales outlets.
