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 instruction executes the function specified by Function Code 06 PLC Ö VFD-B, PLC sends: “01 06 2000 1770 52”

VFD-B Ö PLC, PLC receives: “01 06 2000 1770 52” (No data processing on received data)

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

When X0 = ON, MODRW instruction executes the function specified by Function Code 06 PLC Ö VFD-B, PLC sends: “01 06 2000 1770 8C 1E”

VFD-B → PLC, PLC receives: “01 06 2000 1770 8C 1E” (No data processing on received data)

Program Example 9: COM2 (RS-485), Function Code H0F

1.Function code K15 (H0F): write in multiple bit devices. Up to 64bits can be written.

2.PLC1 connects to PLC2: (M1143 = OFF, ASCII Mode), (M1143 = ON, RTU Mode)

3.For ASCII or RTU mode, PLC COM2 stores the data to be sent in D1256~D1295 and the received data in D1070~D1085.
