7.1 General information
With an individual web browser (e.g. Internet Explorer) all measured
values available in the signal conditioning instrument can be dis-
played in the requested form and unit. The measured value indication
is carried out as HTML chart. Within a company network the enquiry
is made via Ethernet. If a remote enquiry is necessary, a signal
conditioning instrument with RS232 interface and connected modem
is used.
The measured value enquiry can be also carried out via an individual
http-capable software, e.g. Excel.
7.2 Access protection
To prevent unauthorised access to the measured values, the signal
conditioning instrument can be provided with access protection. Use
the web browser and enter the host name or the IP address of the
instrument. Under "Settings - General" you can define the user name
and the password and activate the access protection. When the page
is called up, the default user name and password are asked for first of
all. Enter "VEGA" for user name and password. Now you can activate
the access protection for measured value enquiry and enter your own
password.
The access protection applies also to measured value and instrument
trend files which can be called up via http.
Note:
This access protection only prevents measured value enquiry via web
browser. If the configuration of the signal conditioning instrument also
needs to be protected against unauthorized access, a second access
protection is available. This protection is configured with PACTware or
the respective DTM.

First of all, enter the host name or IP address and subnet mask direct-
ly via the adjustment unit of the signal conditioning instrument under
"Device settings" (see operating instructions manual of the respec-
tive instrument). Briefly interrupt the supply voltage, the instrument
can then be accessed anywhere in the network via the host name
and IP address. Install the configuration software PACTware with the
appropriate DTMs for your instrument on any network PC. Now carry
out the parameter adjustment of the individual measurement loops or
