c)
If the optional DNP 3.0 module has been installed, the DNP 3.0 communication protocol is automatically selected.
d)
If the optional communication module is not installed, a warning of a faulty communication module appears on the LCD together with the fault
code.
The measured currents can be read with parameters I1...I4, the calculated phase
discontinuity value with parameter I5, the status of light detection with parameter
I6, the CB position with parameter I7 and the status of the digital inputs with
parameters I8...I12.

When the value is 1, the digital input is energized.
Each protection stage has its internal output signal. These signals can be read with
parameters O1...O26 and the recorded functions with parameters O61...O86. The
state of the output contacts can be read or changed with parameters O41...O49 and
the recorded functions read with parameters O101...O109.
