trolled, one binary input (single point indication) or two binary inputs (double point in-
dication) may be used for this process.
The capability of switching primary equipment can be restricted by a setting associat-
ed with switching authority (Remote or Local), and by the operating mode (inter-
locked/non-interlocked, with or without password request).
Processing of interlocking conditions for switching (e.g. switchgear interlocking) can
be established with the aid of integrated, user-configurable logic functions.
The operating messages provide information about conditions in the power system
and the device. Measurement quantities and values that are calculated can be dis-
played locally and communicated via the serial interfaces.
Device messages can be assigned to a number of LEDs on the front cover (allocat-
able), can be externally processed via output contacts (allocatable), linked with user-
definable logic functions and/or issued via serial interfaces.
During a fault (system fault) important events and changes in conditions are saved in
fault protocols (Event Log or Trip Log). Instantaneous fault values are also saved in
the device and may be analized subsequently.
Serial interfaces are available for the communication with operating, control and
memory systems.
A 9-pole DSUB socket at the front panel is used for local communication with a per-
sonal computer. By means of the SIPROTEC operating software DIGSI, all operation
and evaluation tasks can be executed via this user interface, such as specifying and
modifying configuration parameters and settings, configuring user-specific logic func-
tions, retrieving operational messages and measured values, inquiring device condi-
tions and measured values, issuing control commands.
Depending on the individual ordering variant, additional interfaces are located on the
rear side of the device. They serve to establish an extensive communication with other
digital operating, control and memory components:
The service interface can be operated via electrical data lines or fiber optics and also
allows communication via modem. For this reason, remote operation is possible via
personal computer and the DIGSI operating software, e.g. to operate several devices
via a central PC.
The additional port (only 7SJ64) is designed exclusively for connection of a RTD-Box
(= resistance temperature detector) for entering external temperatures. It can also be
operated via data lines or fibre optic cables.
The system interface ensures the central communication between the device and the
substation controller. It can also be operated via data lines or fibre optic cables. For
the data transfer Standard Protocols according IEC 60870 870-5-103 are available via
the system port. The integration of the devices into the automation systems SINAUT
LSA and SICAM can also take place with this profile.
The EN-100-module allows the devices to be integrated in 100-Mbit-Ethernet commu-
nication networks in control and automation systems using protocols according to
IEC61850. Besides control system integration, this interface enables DIGSI-commu-
nication and inter-relay communication via GOOSE.
Alternatively, a field bus coupling with PROFIBUS FMS is available for SIPROTEC 4.
The PROFIBUS FMS according to DIN 19245 is an open communication standard
that has particularly wide acceptance in process control and automation engineering,
with especially high performance. A profile has been defined for the PROFIBUS com-
