Program example 10: COM1 (RS-232) / COM3 (RS-485), Function Code H0F
1. Function code K15 (H0F): write in multiple bit devices. Up to 64 bits can be written
2. PLC1 connects to PLC2: (M1143 = OFF, ASCII mode), (M1143 = ON, RTU mode)
3. PLC COM1/COM3 will not process the received data.
4. Take the connection between PLC1 (PLC COM3) and PLC2 (PLC COM1) for example, the
tables below explain the status when PLC1 force ON/OFF Y0~Y17 of PLC2.
Set value: K4Y0=1234H
Device Status Device Status Device Status Device Status
Y0 OFF Y1 OFF Y2 ON Y3 OFF
Y4 ON Y5 ON Y6 OFF Y7 OFF
Y10 OFF Y11 ON Y12 OFF Y13 OFF
Y14 ON Y15 OFF Y16 OFF Y17 OFF
z If PLC applies COM1 for communication, the below program can be usable by changing:
1. D1109→D1036: communication protocol
2. M1136→M1138: retain communication setting
