Short summary

Name	`SEL_2D_ARRAY`
→POU type	→function
Category	IEC-block, SelectEnh, block with internal error diagnostic
Conform to →IEC-standard	not defined in IEC-standard
Graphical interface	Detail on the displayed interface: Due to the setting `hideOutputOfVarInOut`, only the input connection point of the in-out variables `IN` und `IN1` are displayed. Subsequently, the straight lines between the input connection point and the output connection point are also not displayed . Hence, the interface is displayed as similar to the `SEL` block as possible (and to the other provided SEL blocks respectively).
Available since	version 3.2.4 (for library `Standard` ) – initial variant

Functionality

As the SEL block: The block makes a binary selection. In contrast to that block, SEL_2D_ARRAY allows the connection with 2 dimensional arrays .

Inputs, return value

	Identifier	→Data type	Description
Inputs:	`G`	`BOOL`	selector
In-outs (VAR_IN_OUT):	`IN0`	`ARRAY [,] OF` `REAL`, `LREAL`, `USINT`, `UINT`, `UDINT`, `ULINT`, `SINT`, `INT`, `DINT` or `LINT` (corresponds to →generic data type `ANY_NUM`)	1st value
In-outs (VAR_IN_OUT):	`IN1`	`ARRAY [,] OF` `REAL`, `LREAL`, `USINT`, `UINT`, `UDINT`, `ULINT`, `SINT`, `INT`, `DINT` or `LINT` (corresponds to →generic data type `ANY_NUM`)	2nd value
Return value:	–	`ARRAY [,] OF` `REAL`, `LREAL`, `USINT`, `UINT`, `UDINT`, `ULINT`, `SINT`, `INT`, `DINT` or `LINT` (corresponds to →generic data type `ANY_NUM`)

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

Internal error diagnostic for block

The block checks whether the size of the arrays for IN0, IN1 and for the return value amounts to the same rows and the columns. If this is not the case, the output ENO of the block is set to value FALSE (or an equivalent).

Example for usage within ST-editor

See "SEL block " for a basic example of the functionality.
