FUN 190
BCD
BCD conversion
Expression
Input − [ A BCD B ]− Output
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 = S051) is set to ON.

Example
When R019 is ON, the data of D0211 is converted into
For example, if D0211 is 5432, the BCD data H5432 is stored in RW22.
D0211 Binary to BCD
5432
RW22
H5432
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 = S051) is set to ON.
