摘要
用串行接口控制方式取代传统的变频控制方式,可大大减少布线工作量和故障几率,满足现代生产对变频器的实时控制要求。本文对变频器组网控制进行了初步探讨,并给出了变频器和PLC以及PLC和工控机串口通讯的实际例子。
A serial interface control mode is proposed instead of the traditional one controlled by the transducer. The paper introduces the networked group control of inverters. Practical examples on communication with serial interface between inverter and PLC as well as between PLC and industrial PC are also presented.
