3. Instruction Set

3-343

D5 0000 H

PLC converts ASCII codes in 2105 H and stores the converted

data automatically.

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

When X0 = ON, MODRW instruction executes the function specified by Function Code 03

PLC Ö VFD-B, PLC sends: ” 01 03 2100 0006 CF F4”

VFD-B Ö PLC, PLC receives: “01 03 0C 0000 0503 0BB8 0BB8 0000 012D 8E C5”

Program example 5: COM2(RS-485), Function Code H05

1. Function code K5(H05): Force ON/OFF bit device

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

3. n = 1 indicates Force ON (set FF00H) and n = 0 indicates Force OFF (set 0000H)

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

the received data in D1070~D1085

5. Take the connection between PLC1 (PLC COM2) and PLC2 (PLC COM1) for example, the

tables below explain the status when PLC1 Force ON PLC2 Y0.
