communication mode by default.
(2) COM2-RS232 and COM2-RS485 of XDC series cannot be used simultaneously; when
configured in programming software, the port number is COM2.
(3) If COM1 cannot communicate with PC after changing the parameters, please click [stop
PLC when reboot] in the software and then power on again to solve the problem; if
unnecessary, it is better not to modify COM1 communication parameters.
