Function - Get the maximum of two integers.
IN1 : DINT First input
IN2 : DINT Second input
Q : DINT IN1 if IN1 > IN2; IN2 otherwise
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.
Q := MAX (IN1, IN2);
(* The comparison is executed only if EN is
(* ENO has the same value as EN *)
Op1: LD IN1
ST Q (* Q is the maximum of IN1 and IN2 *)
MIN LIMIT MOD ODD
