Flexible and transparent software system enabling measurement and control systems data access
The OPC-Server is a software from Wallace & Tiernan® systems and is designed for data exchange with superimposed systems supporting every Wallace & Tiernan RS 485 bus compatible system. Data exchange is bidirectional, this means the OPC client can both read and write process data; process parameters can be changed from the visualization level. Access to the Wallace & Tiernan RS 485 bus system takes place via a free serial port of the computer on which the OPC-Server application is running.
