7.4.2.13 Differentiator
The calculation differentiates the input signal by time: Output = ∆input / ∆t.
If the source signal is invalid, no further values are calculated. The output signal is indi-
cated as invalid. As soon as the source signal is valid again, new values are calculated.
7.4.2.14 Cartesian to polar coordinates
The calculation converts two input channels representing the position (x, y) of a point in
the Cartesian coordinates system into the corresponding polar coordinates. You will
need the measured values of a different channel for the calculation, e.g. via the ClipX
bus. The calculation results in two output channels: one with the angle values (θ, theta)
and one with the radius values (r). The value range for the angle extends from -179.99°
to +180°. Multiply the value by π/180 as necessary to get the radian measure (rad).

Abb. 51: Example for coordinates transformation
If one of the source signals is invalid, all the output signals will become invalid as well.
The calculation will nevertheless be performed and the result exported.
7.4.2.15 Polar-to-Cartesian coordinates
The calculation converts two input channels representing the position (Radius r, Angle θ
= theta) of a point in polar coordinates into the corresponding Cartesian coordinates.
You will need the measurement values of a different channel for the calculation, e.g. via
the ClipX bus. The calculation results in two output channels: one with the x values and
one with the y values. The angle value must be in degrees (-360° to +360°).
