Communication
Serial interfaces are available for the communication with operating, control and memory systems.
A 9-pin DSUB socket on the front panel is used for local communication with a personal computer. 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 and fault messages and measured values, reading out and dis-
playing fault recordings, inquiring device conditions and measured values, issuing control commands.
To establish an extensive communication with other digital operating, control and memory components the
device may be provided with further interfaces depending on the order variant.
The service interface
can be operated via the RS232 or RS485 interface and also allows communication via
modem. For this reason, remote operation is possible via PC and the DIGSI operating software, e.g. to operate
several devices via a central PC.
The system
interface is used for central communication between the device and a control center. It can be op-
erated through the RS232, the RS485 or the FO port. Several standardized protocols are available for data
transmission. An EN 100 module allows integrating the devices into 100 MBit Ethernet communication net-
works of the process control and automation system, using IEC 61850 protocols. In parallel to the link with the
process control and automation system, this interface can also handle DIGSI communication and inter-relay
communication using GOOSE messaging.
Another interface is provided for the time synchronization
of the internal clock via external synchronization
sources (IRIG-B or DCF77).
Other interfaces provide for communication between the devices at the ends of the protected object. These
protection data interfaces
have been mentioned above in the protection functions.
The operator and service interface allow to operate the device remotely or locally. This is possible during com-
missioning, checking and also during operation with the devices at all ends of the protected object via a com-
munication network. A „WEB Monitor“, is provided which has been optimized for differential protection.
