Introduction
1.2 Application Scope
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 communication with external operating, control and memory
systems.
Local communication with a PC is possible via the USB-DIGSI interface on the front. The DIGSI 4 operating soft-
ware enables you to perform all operational and evaluation tasks, for example entering and modifying config-
uration and setting parameters, configuring user-specific logic functions, reading out operational indications,
fault indications and measured values, reading out and displaying fault records, retrieving device conditions
and measured values, issuing control commands.
Depending on the order variant, additional interfaces are located on the side of the device. They serve for
establishing extensive communication with other digital operating, control and memory components:
Port F serves for central communication between the device and a control center. It can be operated via
copper lines or optical fiber. Standardized protocols, for example, IEC 61850, are available for data transmis-
sion. These protocols are equally used to integrate the devices into substation automation systems, for
example, SICAM PAS.
Alternatively, additional connection options are available with serial DNP3.0 RS485 protocols. If an EN100
module is available, you can use the protocols DNP3 TCP, IEC61850, IEC 60870-5-104, or PROFINET. Further-
more, connecting a SICAM I/O unit is possible via IEC61850 GOOSE.
