Operation Using a Personal Computer

15.1

Overview

All the settings and data of the 7UT51 relay are
available to a PC connected to the communications
port. At the computer, the data can be easily read on
the screen, changed, saved to disk, or printed. To do
this, Siemens provides Windows-based software,
called WinDIGSI.
Personal Computer Interface
A front panel 25-pin RS-232 port is available for
connection to a PC. This port is intended for the
engineer or technician for connection locally at the
substation, using the WinDIGSI software supplied with
the relay to configure the relay as needed.
Remote Interface
An RS-232 port on the rear of the case provides
remote interface for configuring the relay from another
facility. This port is transient hardened. The protocol is
based on the international IEC-870-5 standard.
This port may be configured in software for modem
communication (10-bit) using WinDIGSI software
standing alone, using WinDIGSI in concert with
WinTerm, ProComm or other terminal emulation
software for dial up, or using WinDIGSI with dial up
software provided by third-party telephone port
switching devices.
This port may also be software configured to include
an 11th bit for added data security. This would allow a
relay being used as an intelligent electronic device
(IED) for substation automation and integration. For
more information on protocol and data definition,
consult Siemens.
Configuration & Analysis Software
Windows-based PC software supplied with the relay
(WinDIGSI) provides access to settings, configuration,
metering information, and event logs. Relays may be
programmed off-line. Archiving, file management, and
rapid loading and altering of programs are also
supported. WinDIGSI provides an easy-to-use
graphical user interface.
In addition, captured waveforms may be viewed with
the inclusion of a Windows-based, full-function digital
oscillographic analysis program (WinDIGRA).

Operation Using a Personal Computer
WinDIGSI provides the ability to configure a relay or a
whole system of relays from one personal computer.
The Windows-based software allows the user to
configure a relay for various types of protection. It also
allows the user to retrieve and analyze event data.
Displaying data including waveform captures is an
integral part of the software.
