MIN

Function - Get the minimum of two integers.

Inputs

IN1 : DINT First input
IN2 : DINT Second input

Outputs

Q : DINT   IN1 if IN1 < IN2; IN2 otherwise

Remarks

In LD language, the input rung (EN) enables the operation, and the output rung keeps the state of the input rung. In IL language, the first input must be loaded before the function call. The second input is the operand of the function.

ST Language

Q := MIN (IN1, IN2);

FBD Language

(* The comparison is executed only if EN is TRUE *)
(* ENO has the same value as EN *)
