Platform
TelGas Web is a versatile embedded web server platform designed to provide a database, web server and local connectivity via LAN to a host SCADA system.

Full graphical mimics are supported and can be selected from the menu.

The interface can be customised to adapt to the requirements of the instrument it is connected to.

Supervisory control functions are also supported, for example

• Change alarm limit
• Inhibit channel

TelGas Web provides alarm reporting, event triggered logging and periodic background logging.

Self Auditing System
This is a Memory Watch function which detects changes in the instrument’s configuration.
Changes are time stamped, logged, and sent in an email. Thus accurate records of set point changes or calibration values can be automatically maintained.

Technology
TelGas Web utilises highly optimised browser techniques which enhance functionality and greatly reduce bandwidth; an important factor when accessed by mobile phones and other portable devices.

The integrated database can be queried directly via the web and allows data and events to be exported.
