Program example 5: COM2(RS-485), Function Code H05
1. Function code K5(H05): Force ON/OFF bit device
2. ELC1 connects to ELC2: (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, ELC COM2 stores the data to be sent in D1256~D1295 and stores
the received data in D1070~D1085
5. Take the connection between ELC1 (ELC COM2) and ELC2 (ELC COM1) for example, the
tables below explain the status when ELC1 Force ON ELC2 Y0.
