Input and output signals
The measured currents and the status of the binary input signal can be read (R) with
parameters I1...I4. When the value of parameter I4 is 1, the binary input is energized.

Binary input signal BI I4 0 or 1
Each protection stage has its logical output signal. These signals can be read (R) with
parameters O1...O4. The state of the output contacts can be read (R) or changed (W)
with parameters O5...O8. Functions indicated by parameters O1…O8 are recorded
and they can be read with parameters O21…O28.
