Usage: Script or steady state.
Function Groups: Trigonometric Math
Related to: ACos | ASin | Cos | Sin | Tan
Format: ATan(X)
Parameters:  
X
Required. Any numeric expression.
Comments:

The returned angle is in radians. To convert an angle from radians to degrees, divide by \Pi / 180 or (approximately) 0.0174533.

(\Pi is a defined constant in VTScada.)

Example:

  RadAngle = ATan(1);
  DegAngle = RadAngle / \Pi / 180;

The value of DegAngle will be 45.
