Function
A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Converts a binary value to a BCD (Binary Coded Decimal) value
Inputs
IN : DINT Integer value
Outputs
or 0 if IN is less than 0

Remarks
The input must be positive. In FFLD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung.
In IL "Instruction list"
This is a low-level language and resembles assembly, the
input must be loaded in the current result before calling the function.
ST Language
Q := BIN_TO_BCD (IN);
FBD Language
FFLD Language
(* The function is executed only if EN is TRUE *)
(* ENO keeps the same value as EN *)
