product description

A combination of established M-Bus standards together with OPC-UA seminal communication allowing, up to 80 meters (from diverse manufacturers) to be read out simultaneously (a maximum 40 meters in standard configuration) and their data to be reliably transmitted to the control system. At the same time it is possible to operate a large number of meter and topology types simultaneously with a Beckhoff control unit.
