Abstract
The invention discloses an actuator remote control system which comprises an actuator internally provided with a first Modbus communication unit and an actuated mechanism internally provided with a second Modbus communication unit, wherein the actuator receives a control signal sent by a control center through the first Modbus communication unit, while performing data interaction with the second Modbus communication unit of the actuated mechanism through the first Modbus communication unit. The actuator remote control system, disclosed by the invention, eliminates the traditional analogue value control and switching value control manners, and eliminates the output manners of analogue value output and switching value output; all the control manners and the output manners are completed through the adoption of the Modbus communication, so that the reliability of the actuator remote control system is improved.
