- Actual measured values can be read
- Setting values for main and second sets and switchgroup settings
can be read and, if necessary, changed using a security password
- Status information of output relays etc. can be read and written with
password
- Recorded fault parameters can be read and erased
- Spontaneous reporting of selected events to an event recorder or a
printer
