Example 1: Modifying communication format of COM2
1. Add the below instructions on top of the program to modify the communication format of COM2. When PLC
switches from MANU to AUTO, 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)
