1. If S and D are used in device F, only 16-bit instruction is applicable.

Operands:

: Source of data

: Conversion result

Explanations:

1. The content in S (BIN value) is converted into BCD value and stored in D.

2. As a 16-bit instruction, when the conversion result exceeds the range of 0 ~ 9,999, M1067 and

M1068 will be On.

3. As a 32-bit instruction, when the conversion result exceeds the range of 0 ~ 99,999,999, M1067

and M1068 will be On.

4. The four arithmetic operations and applications in DOP-EXIO series and the execution of INC and

DEC instructions are performed in BIN format. Therefore, if the user needs to see the decimal

value display, simply use this instruction to convert the BIN value into BCD value.

Program Example:

When X0 = On, the binary value of D10 will be converted into BCD value, and the 1s digit of the

conversion result will be stored in K1Y0 (Y0 ~ Y3, the 4 bit devices).
