  1. 11. PLC Protocols

11.14 MODBUS RTU Slave (All function)/(All function OneBaseAddress)

Supported Series: MODBUS RTU CONTROLLER

HMI works as MODBUS MASTER coontecting with SLAVE.

The address in [All function] start from 0, the address in [All function OneBaseAddress] start from 1 (offset 1).

✎Note:

Modbus can also support getting bit from the word, which could access the address such as 100.1 and other formats. The function codes sent out are the same as those that read and write words.

Station number for more than one slaves

If there are more than one slaves connected to HMI, please set slave station number during editing address, as below shows.

Cable wiring

1) RS485

2) RS232

✎Note:

COM3 is available in PI8000 series and advanced series;
