		Received data

ASCII mode: No processing on received data .

RTU mode: No processing on received data .

RST M1318 Reset M1318

ASCII mode (COM3: M1320 = OFF, COM1: M1139 = OFF):

When X0 = ON, MODRW executes the function specified by Function Code H0F PLC1 Ö PLC2, PLC sends: “ 01 0F 0500 0010 02 3412 93 ”

PLC2 Ö PLC1, PLC receives: “ 01 0F 0500 0010 DB ” (No data processing on received data)

RTU mode (COM3: M1320 = ON, COM1: M1139 = ON):

When X0 = ON, MODRW executes the function specified by Function Code H0F PLC1 Ö PLC2, PLC1 sends: “01 0F 0500 0010 02 34 12 21 ED”

PLC2 Ö PLC1, PLC1 receives: “01 0F 0500 0010 54 CB” , (No data processing on received data)
