Dataforth OPC server
The OPC server for the MAQ 20 Industrial Data Acquisition & Control System is designed for broader-based data collection and analysis. The server uses Kepware Technologies’ KEPServerEX OPC server and Modbus/TCP driver, which have been configured for the MAQ20 system. The server comprises three basic parts: channels, devices and tags. The channel represents the communication medium from the host computer to one or more devices; the device is the hardware with which the server communicates; and the tag represents addresses within the hardware with which the server communicates.
