D1074 Low byte FF H

D1075 Low byte 00 H

Data content (ON = FF00H)

D1076 Low byte 8C H CRC CHK Low

D1077 Low byte F6 H CRC CHK High

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

z 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
