Short summary

Name	`TO_BCD_LWORD`
→POU type	→function
Category	IEC-block, Convert
Conform to →IEC-standard	no restrictions
Graphical interface
Available since	version 1.22.0 (for logi.CAD 3)

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 16 digits, only the 16 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.

Inputs, return value

	Identifier	→Data type	Description
Inputs:	`IN`	`USINT`, `UINT`, `UDINT`, `ULINT`, `SINT`, `INT`, `DINT` or `LINT`(corresponds to →generic data type `ANY_INT`)	decimal input value
Return value:	–	`LWORD`

Input EN and output ENO are available when →calling the block. See "Execution control: EN, ENO" for information on input EN and output ENO.

Example for usage within ST-editor

PROGRAM Test
    VAR
        result1, result2 : LWORD;
    END_VAR
    result1 := TO_BCD_LWORD(IN := 215_832_767);                (* The variable 'result' evaluates to '16#0000_0002_1583_2767' (decimal: 8_950_851_431). *)
    result2 := TO_BCD_LWORD(IN := 238_183_205_215_832_767);    (* The variable 'result' evaluates to '16#8183_2052_1583_2767' (decimal: 9_332_338_389_762_123_623). *)
(* Note: The single underscore character '_' has been inserted as separator to make the decimal values in the sample more readable. *)
END_PROGRAM
