Example 1: Modifying COM1 communication format
1. Add the below instructions on top of the program to modify the communication format of
COM1. When PLC switches from STOP to RUN, the program will detect whether M1138 is
ON in the first scan. If M1138 is ON, the program will modify the communication settings of
COM1 according to the value set in D1036
2. Modify COM1 communication format to ASCII mode, 9600bps, 7 data bits, even parity, 1 stop
bits (9600, 7, E, 1).

Example 2: Modiying COM2 communication format
1. Add the below instructions on top of the program to modify the communication format of
COM2. When PLC switches from STOP to RUN, the program will detect whether M1120 is
ON in the first scan. If M1120 is ON, the program will modify the communication settings of
COM2 according to the value set in D1120
2. Modify COM2 communication format to ASCII mode, 9600bps, 7 data bits, even parity, 1 stop
bits (9600, 7, E, 1)
