5.5 Marshalling of binary inputs, binary outputs and LED indicators
5.5.1 Introduction
Thefunctions of the binary inputs and outputs repre-
sented in the general diagrams (Appendix A) relate
to the factory settings. The assignment of the inputs
and outputs of the internal functions can be rear-
ranged and thus adapted to the on-site conditions.
Marshalling of the inputs, outputs and LEDs is per-
formed by means ofthe integrated operator panel or
viathe operating interface inthe front. The operation
ofthe operator panel isdescribed indetail inSection
6.2. Marshalling begins at the parameter address
6000.
The input of the codeword is required for marshal-
ling (refer Section 5.3.1). Without codeword entry,
parameters can be read out but not be changed.
During codeword operation, i.e. from codeword
entryuntil the termination ofthe configuration proce-
dure, the solid bar in the display flashes.
When the firmware programs arerunning the specif-
ic logic functions will be allocated to the physical in-
put and output modules orLEDs in accordance with
the selection.
Example: A start signal is registered. This event is
generated in the device as an ”Annunciation” (log-
ical function) and should be available at certain ter-
minals of the unit as a N.O. contact. Since specific
unit terminals are hard-wired to a specific (physical)
output relay, e.g. to the signal relay 1, the processor
must be advised that the logical signal ”BFP
Start” should be transmitted to the signal relay 1.
Thus, when marshalling is performed two state-
ments of the operator are important: Which (logical)
annunciation generated in the protection unit pro-
gram should trigger which (physical) output relay?
Up to 20 logical annunciations can trigger one
(physical) output relay.
A similar situation applies to binary inputs. In this
case external information (e.g. ”Trip L1 by feeder
protection”) is connected to the unit via a (physical)
input module and should initiate a (logical) function,
namely start of the breaker failure protection. The
corresponding question to the operator is then:
Which signal froma (physical) inputrelay should ini-
tiate which reaction in the device? One physical in-
put signal can initiate up to 10 logical functions.
The trip relays can also be assigned different func-
tions. Each triprelay canbe controlled byeach com-
mand function or combination of command func-
tions.
The logical annunciation functions can be used in
multiple manner.E.g. one annunciation functioncan
trigger several signal relays, several trip relays, addi-
tionally beindicated byLEDs, and becontrolled bya
binary input unit. The restriction is, that thetotal ofall
physical input/output units (binaryinputs plussignal
relays plus LEDs plus trip relays) which areto beas-
sociated withonelogical function must not exceed a
number of 10. Ifthis number is tried tobe exceeded,
the display will show a corresponding message.
The marshalling procedure is set up such that for
each (physical) binary input, each output relay, and
for each marshallable LED, the operator will be
asked which (logical) function should be allocated.
The offered logical functions are tabulated for the
binaryinputs, outputs and LEDs inthe following sec-
tions.
The beginning of the marshalling parameter blocks
is reached by directly selecting the address 6000,
i.e.
--- press direct address key DA,
--- enter address 6 0 0 0,
--- press enter key E
or by paging with keys Ý (forwards) or ß (back-
wards) until address 6000 has been reached. The
beginning of the marshalling blocks then appears:
