MIN block

Short summary

Name	`MIN`
→POU type	→function
Category	Standard (safe), Select
Conform to →IEC-standard	currently restricted (IEC demands data type `ANY_ELEMENTARY` for the inputs, hence the following data types are demanded as well: `LTIME`, `STRING`, `WSTRING`, `CHAR`, `WCHAR`, `LDATE_AND_TIME`, `LTIME_OF_DAY` and `LDATE`. Currently, these data types are not supported for the block.)
Graphical interface
Available since	version 1.22.0 (for Neuron Power Engineer) - initial variant version 3.8.0 (for library `Standard (safe)`): block provided in this library

Functionality

The block returns the minimum value of all values connected at the inputs: MIN(IN1, IN2, ..., IN16)

Bitstring values (= ANY_BIT values; see →generic data type} are treated like unsigned →integer values by the block. This behavior is a specification according to the →IEC-standard.

Inputs, return value

Return value:	–	`REAL, LREAL, USINT, UINT, UDINT, ULINT, SINT, INT, DINT, LINT, TIME, BOOL, BYTE, WORD, DWORD, LWORD, DATE_AND_TIME, DATE or TIME_OF_DAY`

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

        result : INT;

    END_VAR

    result := MIN(IN1 := 3, IN2 := 345, IN3 := -3, IN4 := 999, IN5 := 4);       (* The variable 'result' evaluates to '-3'.  *)

END_PROGRAM
