Starting up the ClipX
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.
7.4.2.11 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°).

7.4.2.12 PID controller
This calculation implements a PID controller in parallel structure. The PID (Pro-
portional Integral Derivative) controller consists of three elements: the P term, I
term and D term. The parallel structure of the controller prevents a wind-up
effect. You can limit the output signal via Y and Y . When one of the values
max min
is reached the Min/Max Flag is set. T is the parasitic time constant at 1/update
d
rate = 1 ms.
