Modbus® RTU is a globally used, open data communications protocol that allows a single master controller, such as a PLC, to easily interface with multiple, uniquely addressed Verderflex Vantage 5000 pumps in a digitally controlled, high resolution dosing or metering system. Vantage 5000 pumps can be networked over an industry standard, license free data network, simplifying the integration of the Vantage 5000 into PLC controlled data highways. MODBUS RTU allows a network of Vantage 5000 pumps to be uniquely identified and controlled by a single master controller PLC or computer with real-time parameter feedback and alarms.
