Rotork’s Modbus module allows actuators to be connected to a 2-wire RS485 network for direct communication to a PLC or DCS using Modbus RTU protocol. Modules are available for standard single and dual (redundant) communication highways. In addition, a redundant loop network can be created with the single and repeater Modbus card. Status, alarms and control functions are available over the Modbus network.
