Application manual
It is possible to handle up to 40 analog and 352 binary signals, either internal
signals or signals coming from external inputs. The binary signals are identical in
all functions that is, Disturbance recorder (DR), Event recorder (ER), Indication
(IND), Trip value recorder (TVR) and Event list (EL) function.
User-defined names of binary and analog input signals is set using PCM600. The
analog and binary signals appear with their user-defined names. The name is used
in all related functions (Disturbance recorder (DR), Event recorder (ER), Indication
(IND), Trip value recorder (TVR) and Event list (EL)).
Figure 100 shows the relations between Disturbance report, included functions and
function blocks. Event list (EL), Event recorder (ER) and Indication (IND) uses
information from the binary input function blocks (BxRBDR). Trip value recorder
(TVR) uses analog information from the analog input function blocks (AxRADR),
which is used by Fault locator (FL) after estimation by Trip Value Recorder (TVR).
Disturbance report function acquires information from both AxRADR and
BxRBDR.
