M1127

Processing received data

ASCII mode: The received data is stored in D1070~D1085 in ASCII format

RTU mode: The received data is stored in D1070~D1085 in Hex.

RST M1127 Reset M1127

ASCII mode (M1143 = OFF):

When X0 = ON, MODRW instruction executes the function specified by Function Code 05 PLC1 Ö PLC2, PLC sends: “01 05 0500 FF00 6F”

PLC2 Ö PLC1, PLC receives: “01 05 0500 FF00 6F”
