Functionality
The block converts a decimal value into a binary coded decimal value (a →BCD-value) .
At input IN, connect the decimal value that should be converted. If the decimal value has more than 4 digits, only the 4 rightmost digits are considered. The remaining digits are not accepted by the data type of the return value. In case of decimal values < 0, the block always returns value 0.

Example for usage within ST-editor
PROGRAM Test
VAR
result1, result2 : WORD;
END_VAR
result1 := TO_BCD_WORD(IN := 4_321); (* The variable
'result'
evaluates to
'16#4321'
(decimal: 17_185). *)
result2 := TO_BCD_WORD(IN := 32_767); (* The variable
'result'
evaluates to
'16#2767'
(decimal: 10_087). *)
(* Note: The single underscore character
'_'
has been inserted as separator to make the decimal values in the sample more readable. *)
