Program example 6: COM1(RS-232) / COM3(RS-485), Function Code H05
1. Function Code K5 (H05): Force ON/OFF bit device.
2. PLC1 connects PLC2: (M1320 = OFF, ASCII Mode ), (M1320 = ON, RTU Mode)
3. n = 1 indicates Force ON (set FF00H) and n = 0 indicates Force OFF (set 0000H)
4. PLC COM1/COM3 will not process the received data.
5. Take the connection between PLC1 (PLC COM3) and PLC2(PLC COM1) for example, the
tables below explains the status when PLC1 reads Y0~Y17 of PLC2
• If PLC1 applies COM1 for communication, the below program can be usable by
changing:
1. D1109→D1036: communication protocol
2. M1136→M1138: retain communication setting
3. D1252→D1249: Set value for data receiving timeout
4. M1320→M1139: ASCII/RTU mode selection
5. M1316→M1312: sending request
6. M1318→M1314: receiving completed flag
