General - Siemens SIPROTEC 7SJ62 Manual

2.23.10.1 General

During the commissioning phase, the device configuration created in the devices must be verified and their
functions be checked. The Web Monitor provides support during the basic and clear determination and display-
ing of important measuring values.
Discrepancies in the wiring or the configuration can be quickly found and solved.
To run the Web Monitor, a link from the operator PC to the protection device via its front and rear operator in-
terface (service interface) is necessary. This can be done directly via the 9-pole DIGSI cable by means of an
existing long-distance data connection. Remote access via a modem is also possible. An Internet browser must
be installed on the operator PC (see paragraph on system requirements). DIGSI 4 is usually also installed on
the operator PC.
Please note that it must be ensured that DIGSI 4 and the Web Monitor do not use the same operator interface
at the same time. A simultaneous serial access would lead to data collisions. This means that either DIGSI 4
OR the Web-Monitor can use a device interface. Before the Web Monitor is started, DIGSI 4 must be exited or
at least the settings and allocations in DIGSI 4 must have been finalized. It is possible to simultaneously
operate DIGSI 4 at the front operator interface via a COM port of the operator PC and the Web Monitor at the
rear operating interface via another COM port of the operating PC.
The Web Monitor consists of HTML pages and the Java-Applets contained therein, which are stored in the
7SJ62/64 SIPROTEC 4 device in EEPROM. It forms an integral part of the SIPROTEC 4 device firmware and
therefore does not need not be installed separately. All that needs to be created on the operator PC is a long-
distance data transmission network used for selection and communication. After the link has been successfully
established through the data transmission network, the browser is started and the TCP-IP address of the pro-
tection device is entered. The server address of the device, which is its homepage address, is transmitted to
the browser and displayed as an HTML page. This TCP-IP address is set at the front and service interface using
DIGSI 4, or directly on the device using the integrated operator interface.
Note
It is only possible to monitor this process. Control of the process through the data transmission link is only pos-
sible after a control feature has been set up and established. A parameter can be modified either directly on
the device or with DIGSI 4 in such manner that the device control feature contained in the Web Monitor also
permits the input of numerical values. Thereafter, the Web Monitor parameters can be modified which are nor-
mally set only directly on the device, because passwords can now be entered from the keyboard.
