PLCSIM OPC Server

View Deal

OPC-based communications for data exchange years ago became a stable standard in industrial hardware and software applications. OPC eliminates the requirement to write a custom interface, or server/driver, to exchange data with hardware field devices. This is achived by defining a common, high performance interface that permits this work to be done once, and then easily reused by HMI, SCADA, Control and custom applications. 

PLCSIM OPC Server – is a self-containing OPC DA Server (supports OPC DA2, DA3 standards), written to easily connect SIEMENS S7-PLCSIM software PLC to any SCADA or HMI, acting as OPC client. Main features are:
