Internal web server
The built in web server can be accessed by entering the IP address in any web browser. A website
will appear that enables you to view and adjust the devices settings. It also provides real time data
visualisation of all available parameters. The data will be updated every second. The image below
shows the internal web server. In order to access the web server, make sure the device is
powered. USB power is sufficient for general configuration. External power needs to be applied to
receive real time read out.
Login
Some part of the web server are password protected. These parts are the ones where settings can
be adjusted. Product details and measurement values are available without logging in. The default
credentials are:
username: admin
password: admin
Above credentials can be changed via the internal web browser, once logged in, or using VPStudio.
7.8
Modbus TCP
Modbus TCP can be used to connect the transmitter to VPVision or a central data acquisition /
building management system.
When connecting to a building management system, it's important to match the Ethernet settings.
The Ethernet settings can be changed with VPStudio, the built in web server or by using the key
pad. Make sure that Modbus master and the transmitter are in the same IP address range.
The communication protocol used is Modbus TCP. The Modbus table is identical to the RS485
interface. More information can be found in the
Modbus chapter 9
.
7.9
Display
The display enables you to read measurement data in real time. In combination with the keypad, it
can also be used to change the most common parameters.
