Processing received data

ASCII mode: The received data is converted to Hex value and stored in registers starting from D0

RTU mode: The received data is stored in registers starting from D0

RST M1318 Reset M1318

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

When X0 = ON, MODRW instruction executes the function specified by Function Code 02 PLC1Ö PLC2, PLC1 sends: “01 02 0500 0010 E8”

PLC2 ÖPLC1, PLC1 receives: “01 02 02 3412 B5”

PLC1 data receiving register D0

Register	Data			Descriptions
D0	1234H	PLC converts the ASCII data in address 0500H~0515H and
		stores the converted data automatically.
