Operands:
S : Source of data D: Conversion result
Explanations:
1. If S and D are used in device F, only 16-bit instruction is applicable.
2. See the specifications of each model for their range of use.
3. Flags: M1067 (operation error); M1068 (operation error); D1067 (error code)
4. The content in S (BIN value) is converted into BCD value and stored in D.
5. As a 16-bit (32-bit) instruction, when the conversion result exceeds the range of 0 ~ 9,999 (0 ~ 99,999,999), and
M1067, M1068 = On, D1067 will record the error code 0E18 (hex).
6. The four arithmetic operations and applications in PLC 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:
1. 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).
X0
BCD D10 K1Y0
2. When D10 = 001E (hex) = 0030 (decimal), the execution result will be: Y0 ~ Y3 = 0000(BIN).
