Short summary

Name	`IAND`
→POU type	→function
Category	IEC-block, BitstringEnh
Conform to →IEC-standard	not defined in IEC-standard
Graphical interface
Available since	version 1.23.0 (for logi.CAD 3)

Functionality

The block returns the result of a bitwise AND operation of all values connected to the inputs of ANY_INT.

Compare: "AND block" for AND operation for values of ANY_BIT.

Inputs, return value

	Identifier	→Data type	Description
Inputs:	`IN1`	`USINT`, `UINT`, `UDINT`, `ULINT`, `SINT`, `INT`, `DINT` or `LINT`(corresponds to →generic data type `ANY_INT`)	1st value
	`IN2`	`USINT`, `UINT`, `UDINT`, `ULINT`, `SINT`, `INT`, `DINT` or `LINT`(corresponds to →generic data type `ANY_INT`)	2nd value
	... (extensible until)
	`IN16`	`USINT`, `UINT`, `UDINT`, `ULINT`, `SINT`, `INT`, `DINT` or `LINT`(corresponds to →generic data type `ANY_INT`)	16th value
Return value:	–	`USINT`, `UINT`, `UDINT`, `ULINT`, `SINT`, `INT`, `DINT` or `LINT`(corresponds to →generic data type `ANY_INT`)

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

See:

"Blocks for safe logic" whether this block is supported for developing safety-relevant applications.
"Highlighting safe logic in the FBD-editor" for the effects when using the block as a block for safe logic .

Example for usage within ST-editor

PROGRAM Test
    VAR
        result1, result2, result3, result4 : INT;
    END_VAR
    result1 := IAND(IN1 := 2, IN2 := 2);      (* The variable 'result1' evaluates to '2'. *)
    result2 := IAND(IN1 := 2, IN2 := 5);      (* The variable 'result2' evaluates to '0'. *)
    result3 := IAND(IN1 := 3, IN2 := 9);      (* The variable 'result3' evaluates to '1'. *)
    result4 := IAND(IN1 := 5, IN2 := 5);      (* The variable 'result4' evaluates to '5'. *)
END_PROGRAM
