Introduction
1.2 Application Scope
Device messages can be assigned to a number of LEDs on the front cover (allocatable), 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 analyzed subsequently.
Communication
The following interfaces are available for the communication with external operating, control and memory
systems.
A 9-pole DSUB miniature female connector on the front panel serves the purpose of local communication with
a PC. By means of the SIPROTEC 4 operating software DIGSI, all operational and evaluation tasks can be
executed via this operator interface, such as specifying and modifying configuration parameters and settings,
configuring user-specific logic functions, retrieving operational messages and measured values, inquiring
device conditions and measured values, issuing control commands.
Depending on the individual ordering variant, additional interfaces are located at the rear side of the device.
They serve to establish extensive communication with other digital operating, control and memory compo-
nents.
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 soft-
ware, 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 tempera-
ture 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. Standard protocols are available to transmit data
according to IEC 60870-5-103 via system port. The integration of the devices into the automation systems
SINAUT LSA and SICAM can also take place with this profile.
An EN 100 module allows integrating the devices into 100-Mbit Ethernet communication networks of the
process control and automation system using IEC 61850, PROFINET or DNP 3.0 TCP protocols. Besides the link
with the process control and automation system, this interface also processes DIGSI communication, interrelay
communication via GOOSE and connection of a SICAM I/O unit.
Alternatively, field bus coupling with PROFIBUS FMS is available for SIPROTEC 4. The PROFIBUS FMS according
to DIN 19245 is an open communication standard that particularly has wide acceptance in process control and
automation engineering, with exceptional high performance. A profile has been defined for the PROFIBUS
communication that covers all of the information types required for protection and process control engi-
neering. The integration of the devices into the power automation system SICAM can also take place with this
profile.
Besides the field-bus connection with PROFIBUS FMS, further coupling options are possible with PROFIBUS DP
and the protocols DNP 3.0 and MODBUS. These protocols do not support all possibilities which are offered by
PROFIBUS FMS.
Furthermore, a redundant IEC 60870-5-103 interface is available.
