3.1.2.2 Signal designations of BP internal signals GUID-764F4101-DC86-4CF1-9017-FD5A8781F16F v1Each BP function provides a set of internal input and output signals. They can be mapped tobinary inputs (optocoupler) and outputs (contacts) of the bay unit by using the correspondingbinary inputs and output signals.Example:BP internal Signal Designation of binary input signalTrip CB L1 211105_DIST TRIP CB L13.1.2.3 Binary input signals of BP GUID-B4B529FA-3ECA-4C05-AF69-405710ED47A4 v1Table 7: BU_ DIST input signalsBP internal signal text Designation of binary input signal DescriptionExt Blk Dist 111205_DIST Ext.
