Control network system with motor control function using smart switch

摘要

Modularization of switches for motors (motors), motor-driven and pneumatic valves, and drivers for operation, implementation of logic functions to simplify switch configuration, and all smart switches connected to one network for control via communication The present invention relates to a control network system that performs a motor control function by using a smart switch to transmit and receive data. An electronic overload relay (EOCR), which cuts off the power supplied to a motor when heat is generated due to an overload of the motor, A first smart device that includes an electromagnetic contactor (MC) for supplying power through the overload relay to the motor, a communication module, and control logic, and controls driving and trip operations in association with the electronic overload relay and the motor connector; To control signals according to the first smart device and the programmable logic controller. A second smart device that transmits through the message communication, a third smart device that transmits an on-site operation signal to the first smart device, a fourth smart device that is connected to the first to third smart devices through address assignment message communication, and A control network system including a programmable logic controller (PLC) for interfacing data with the first and second smart devices through a smart device is implemented to perform a motor control function using a smart switch.
