COM ports (COM1: RS-232, COM2: RS-485, COM3: RS-485) support communication format of
MODBUS ASCII/RTU modes. When RTU format is selected, the data length should be set as 8.
COM2 and COM3 support transmission speed up to 921kbps. COM1, COM2 and COM3 can be
used at the same time.
COM1:
Can be used in master or slave mode. Supports ASCII/RTU communication format, baudrate
(115200bps max), and modification on data length (data bits, parity bits, stop bits). D1036: COM1
(RS-232) communication protocol of master/slave PLC. (b8 - b15 are not used) Please refer to
table below for setting.
COM2:
Can be used in master or slave mode. Supports ASCII/RTU communication format, baudrate
(921kbps max), and modification on data length (data bits, parity bits, stop bits). D1120: COM2
(RS-485) communication protocol of master/slave PLC. Please refer to table below for setting.
COM3:
Can be used in master or slave mode. Supports ASCII/RTU communication format, baudrate
(921kbps max), and modification on data length (data bits, parity bits, stop bits). D1109: COM3
(RS-485) communication protocol of master/slave PLC. (b8 - b15 are not used) Please refer to
table below for setting.
