Input and output signals
The measured voltages 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.
The value of the calculated positive-phase-sequence voltage can be read via
parameter I5.

Binary input signal BI
Positive-phase-sequence voltage
Each protection stage has its internal output signal. These signals can be read (R)
with parameters O1...O8. The state of the output contacts can be read (R) or changed
(W) with parameters O9...O12. When any of the values of parameters O1...O12
changes from 0 to 1, it is recorded in the corresponding parameter of O21...O32. The
values recorded can be read via these parameters and they remain stored until reset.
