COS / COSL

Function - Calculate a cosine.

Inputs

IN : REAL/LREAL  Real value

Outputs

Q : REAL/LREAL   Result: cosine of IN

Remarks

In LD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung. In IL, the input must be loaded in the current result before calling the function.

ST Language

Q := COS (IN);

FBD Language

LD Language

(* The function is executed only if EN is TRUE *)
(* ENO keeps the same value as EN *)

IL Language:
