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 8 digits, only the 8 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 : DWORD;
END_VAR
result1 := TO_BCD_DWORD(IN := 32_767); (* The variable
'result'
evaluates to
'16#0003_2767'
(decimal: 206_695). *)
result2 := TO_BCD_DWORD(IN := 215_832_767); (* The variable
'result'
evaluates to
'16#1583_2767'
(decimal: 360_916_839). *)
(* Note: The single underscore character
'_'
has been inserted as separator to make the decimal values in the sample more readable. *)
