Commissioning aid

2.17.1.1 Function Description

There is a comprehensive commissioning and monitoring tool that checks the communication and the whole
differential protection function. The WEB-Monitor is an integral part of the device. The respective online-help is
available with DIGSI on CD-ROM or via the internet at www.siprotec.de.
To ensure proper communication between the device and the PC browser, several prerequisites must be met.
The transmission speed must be the same and an IP address has to be assigned so that the browser can iden-
tify the device.
Thanks to the WEB Monitor, the user is able to operate the device from a PC. On the PC screen, the front panel
of the device with its operator keyboard is emulated. The actual operation of the device can be simulated using
the mouse pointer. This feature can be disabled.
If the device is equipped with an EN100 module, operation by DIGSI or the WEB Monitor is possible via Ether-
net. This is done by simply setting the IP configuration of the device accordingly. Parallel operation of DIGSI
and WEB Monitor via different interfaces is possible.
WEB-Monitor
The „WEB-Monitor" is a comprehensive commissioning and monitoring tool which enables to clearly display
the differential protection communication and the most important measured data using a PC with a web brows-
er. Measured values and the values derived from them are graphically displayed as phasor diagrams. You can
also view tripping diagrams, scalar values are shown in numerical form. For more details please refer to the
online help for the „WEB-Monitor".
This tool enables to graphically display, for instance, the currents, voltages (if connected to the system) and
their phase angles for all devices of a differential protection system on a PC. In addition to phasor diagrams of
the measured values, the numerical values as well as frequency and device addresses are indicated. Figure
2-112 shows an example.
Additionally the position of the differential and restraint values can be viewed in the tripping characteristic.
