Program example 5: COM2(RS-485), Function Code H05
1.
Function code K5(H05): Force ON/OFF bit device
2.
PLC1 connects to PLC2: (M1143 = OFF, ASCII mode), (M1143 = ON, RTU Mode)
3.
n = 1 indicates Force ON (set FF00H) and n = 0 indicates Force OFF (set 0000H)
4.
For ASCII or RTU mode, PLC COM2 stores the data to be sent in D1256~D1295 and stores
the received data in D1070~D1085
5.
Take the connection between PLC1 (PLC COM2) and PLC2 (PLC COM1) for example, the
tables below explain the status when PLC1 Force ON PLC2 Y0.
