Operation and Data Access

Operation via Web Browser
To handle and display the data, a Java-capable Internet Browser (e.g. Internet explorer) must be
installed on the service computer. A (serial, Intranet, Internet or switched) connection must be
available to access the ChemWeb Server. The Internet Browser has to be started and the IP address
(or PPP-IP address in the case of a switched or null modem connection) has to be entered into the
address line. Up to 50 simultaneous connections are possible!
Navigation window
The navigation window is located on the left-hand side of the Browser screen. Here all traced bus
devices, the name of the ChemWeb Server and the server setup are displayed. By clicking one of the
selection menus, further submenus are opened or a selected page is shown on the right-hand side of
the screen.
If user-specific names have been defined for the bus users, these are displayed instead of the bus
addresses. By clicking such a name, the bus address and the original designation will be displayed
after a short time.
Display and configuration window
For all traced bus devices, the individual submenus of
- “Online values”
- “Configure”
- “Trend”
have been created automatically during bus scan, depending on the device. This means that these
menu items are different from device to device!
