UseDegrees

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Sets the unit for angles in all trigonometric functions.

Inputs

Input	Data Type	Range	Unit	Default	Description
IN	BOOL				If TRUE, turn all trigonometric functions to use degrees. If FALSE, turn all trigonometric functions to use radians (default).

Outputs

Output	Data Type	Range	Unit	Description
Q	BOOL			TRUE if functions use degrees before the call.

Remarks

This function sets the working unit for these functions:

Function	Description
acos / acosL	Calculate an arc-cosine.
asin / asinL	Calculate an arc-sine.
atan / atanL	Calculate an arc-tangent.
atan2 / atan2L	Calculate arc-tangent of Y/X.
cos / cosL	Calculate a cosine.
sin / sinL	Calculate a sine.
tan / tanL	Calculate a tangent.

Op1: LD "Ladder diagram"
Ladder logic is a method of drawing electrical logic schematics. It is now a very popular graphical language for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them   IN
