Diagnosis
During the diagnosis, the "state of health" of the device is checked. It is to be found out if and what
→faults are given in the device.
Depending on the device, the inputs and outputs can also be monitored for their correct function.
- wire break,
- short circuit,
- value outside range.
For diagnosis, configuration and log data can be used, created during the "normal" operation of the
device.
The correct start of the system components is monitored during the initialisation and start phase.
Errors are recorded in the log file.
For further diagnosis, self-tests can also be carried out.

Dither
Dither is a component of the
→PWM signals to control hydraulic valves. It has shown for
electromagnetic drives of hydraulic valves that it is much easier for controlling the valves if the control
signal (PWM pulse) is superimposed by a certain frequency of the PWM frequency. This dither
frequency must be an integer part of the PWM frequency.
