3. 8-bit conversion mode (while M8161 is ON)

(M8161 is used also for the RS, HEX, CCD and CRC instructions.)

Each digit of hexadecimal data stored in

8 bits of each device

stored in high-order 8 bits of each device

M8161 is used also for the RS, HEX, CCD and CRC instructions. When using the 8-bit mode, set M8161 to normally

ON. M8161 is cleared when the PLC mode is changed from RUN to STOP.

In the following program, conversion is executed as follows:

Devices after

D100 = 0ABCH

D101 = 1234H

D102 = 5678H

Number of specified digits (characters) and conversion result

Does not change

Bit configuration in the case of "n = K2"

D 100 = 0ABCH

D200 = B → ASCII code = 42H

D201 = C → ASCII code = 43H

• When outputting data in the BCD format for a printer, for example, it is necessary to convert binary data into BCD

data before executing this instruction.

and later. The number of digits (characters) to be converted is specified by "n". "0" is

16 External FX Device – FNC 80 to FNC 89

16.3 FNC 82 – ASCI / Hexadecimal to ASCII Conversion

and later is converted into an ASCII code, and transferred to low-order

When M8161 is set to ON, the 8-bit mode

is selected. The conversion processing is

executed as follows

[0] = 30H [1] = 31H [5] = 35H

[A] = 41H [2] = 32H [6] = 36H

[B] = 42H [3] = 33H [7] = 37H

[C] = 43H [4] = 34H [8] = 38H
