Instruction 73- Binary Conversion
Expression:
Space Requirement: 1 line x 5 column Location Requirement: Middle, Right rail
Function:
When the input is ON, this instruction converts the 4 digits of BCD data of A into binary, and
stores in B. If any digit of A contains non-BCD code (other than H0 through H9), the conversion is
not executed and the instruction error flag (ERF = S1010) is set to ON.
Execution Condition:
Input Operation Output ERF
OFF No execution OFF ---
ON Normal Execution ON ---
BCD data error OFF Set

Example:
When B017 is ON, the BCD data of BW28 is converted into binary data, and the result is stored
in D0127.
For example, if BW28 is H1234, the binary data 1234 is stored in D0127.
Note:
If any digit of operand A contains non-BCD data, e.g. H13A6, the conversion is not executed and
the instruction error flag (ERF = S1010) is set to ON.
