Instruction 74- BCD Conversion
Expression:
Space Requirement: 1 line x 5 column Location Requirement: Middle, Right rail
Function:
When the input is ON, this instruction converts the binary data of A into BCD, and stores in B. If
the data of A is not in the range of 0 to 9999, 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 B019 is ON, the data of D0211 is converted into 4-digit BCD, and the result is stored in
BW22.
For example, if D0211 is 5432, the BCD data H5432 is stored in BW22.
Note:
If the data of A is smaller than 0 or greater than 9999, the conversion is not executed and the
instruction error flag (ERF = S1010) is set to ON.
