8.5 Load Data Profiling (LDP)
SIL-A relay provides the demand of current with the following characteristics:
•
Number of records: 744
•
Recording mode circular
•
Sampling rate (interval): configurable through communications: 1
–
60 min
•
Record format:
Date/Time
IMAX (in interval)
IMAX (actual)
IA
IB
IC
IN
NOTE:
Once the demand setting is changed, it is necessary to switch the relay off and to switch it on
again to ensure that the new setting is recorded correctly.
8.6 Counters
The following counters are provided:
1. Number of openings of the circuit breaker
2. Amperes accumulated (l2t) during the openings of the circuit breaker
3. Number of reclosings
8.7 Programmable Logic Control (PGC)
Firstly, it is defined the concept of physical input, physical output and logical signal.
Physical inputs are the real inputs of the device. SIL-A device has 6 physical inputs. These inputs are
translated to internal binary states which later, can be assigned to logical signal to get a specific
operation.
SIL-A is provided with 6 outputs. Physical outputs are the real outputs of the device. SIL-A has 6 physical
outputs and the rest of them (up to 32) are logic outputs to be used to configure the relay.
Besides, the relay is provided with 32 alarms. The first 6 alarms correspond to the 6 configurable front
LEDs and the rest are logic alarms to be used to configure the relay.
All the outputs (Physical and logic alarms, physical and logic outputs) are the result of a
PROGRAMMABLE LOGIC CONTROL which can be configured from HMI or from SICom software.
For each output there is a LOGICAL GATE. It can perform a logical operation up to 4 binary states to
obtain other binary result.
In V3 of the PGC the LOGICAL GATES that are supported by SIL-A are:
