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 format.

RST M1127 Reset M1127

ASCII mode (M1143 = OFF)

When X0 = ON, MODRW instruction 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 ”
