Trigger function
To use the trigger function you must first define the trigger conditions.
There are three trigger types available:
1. Start trigger (with maximum four trigger conditions)
2. Stop trigger (with maximum four trigger conditions)
3. Sampling rate trigger (with start and stop)
One start condition and one stop condition (trigger condition) can be:
S a measured value level
S a limit switch
S a measured value band
S an external input signal
These start/stop conditions can be defined independently of each other and
can be combined with each other. The AND function and OR function are
available for this purpose (
