The Electro Technical Characteristics module performs calculations from
two incoming current and voltage data channels for example, the power, the
phase angle, or the input frequencies.
The Polar/Cartesian module converts polar coordinates into cartesian
coordinates and vice versa.
The Resample module converts vibrations at a rotating axis into the rotation
angle, for example, the vibrations of an engine shaft.
The Control Modules Group
The control modules group contains modules for generating signals, for
controlling the data flow in the worksheet, and for executing control
functions.
The Generator module generates various signals such as rectangular signals,
sine signals, or sawtooth signals. The Sequence Generator module
generates time-dependent, analog set points and digital control commands
with a user-defined program. Use the modules Switch, Slider, and Coded
Switch to enter data manually during a measurement.
The Time Delay module outputs incoming data channels with a time delay.
The TTL Pulse Generator generates TTL signals time-dependent in order
to control processes. The Stop module terminates the measurement.
The Latch module outputs the last data value continuously, event-driven, or
after a signal at the control input. The Signal Router module distributes
incoming data values event-driven onto several outputs.
Use the modules PID Control and Two-Point Control to control processes.
The Write Global Variable module saves the incoming measurement values
in variables. The Write Block Time saves time information in strings. The
Read Global Variable module outputs values of variables to the worksheet.
