Siemens PLC and ENC Frequency Inverter RTU Communication

Equipment Introduction
The most common type of industrial automatic control system is a combination PLC and inverter. There are a variety of PLC modes to control the inverter and we use the RS-485 communication method. It features a strong anti-interference ability, high transmission rate and low cost operation. ENC frequency inverters come with a built-in international standard MODBUS (slave) communication protocol to operate and supervise single or multiple inverter units remotely.

Take the Siemens S7-200CPU224XP for example. Here we utilize PLC and ENC frequency inverters to establish communication and realize initiation, frequency input, and monitoring.
