2.3.2.2 Signal designations of BP internal signals
Each BP function provides a set of internal input and output signals. They can be
mapped to binary inputs (optocoupler) and outputs (contacts) of the bay unit by us-
ing the corresponding binary inputs and output signals.
Example:
BP internal Signal Designation of binary input signal
Trip CB L1 211105_DIST TRIP CB L1
