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, thetables below explains the status when PLC1 reads Y0~Y17 of PLC2
