Typical applications:




1 When controlling a module, you can use the MODUBS RTU instruction or the AT instruction. In AT command mode, the dial switch (slave address) is invalid and can only control one module at a time.

 
 
 


MODBUS RTU command mode (HEX), you can control a variety of ways: Serial Hyper Terminal Control (need to manually add the CRC), Modbus Poll software control (software automatically add the CRC), PLC or MCU process control
