IOR block

Short summary

Name	`IOR`
→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 Neuron Power Engineer)

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

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

	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.

PROGRAM Test

VAR

        result1, result2, result3, result4 : INT;

    END_VAR

    result1 := IOR(IN1 := 2, IN2 := 2);      (* The variable 'result1' evaluates to '2'. *)

    result2 := IOR(IN1 := 2, IN2 := 5);      (* The variable 'result2' evaluates to '7'. *)

    result3 := IOR(IN1 := 5, IN2 := 2);      (* The variable 'result3' evaluates to '7'. *)

    result4 := IOR(IN1 := 5, IN2 := 5);      (* The variable 'result4' evaluates to '5'. *)
