Ambrit demonstrates Data Acquisition over the Internet
NORTHCHURCH, England, July 8 2001. Ambrit demonstrates a new concept providing an example of Data Aquisition through the Internet using Webspring.
Webspring can be used to access data from almost any computerised instrumentation, providing real-time access using only a browser.
In this instance we have setup a demonstration of a secure Internet connection to a live FloBoss S600 via a Webspring server located at Ambrit’s facility in Northchurch, Hertfordshire, England.
The demonstration shows secure real-time data from a FloBoss S600 configured as a Gas Flow computer. The data is displayed in numerical and graphical form and can be accessed securely from anywhere in the world using only an Internet browser. Access to all measured and calculated variables in FloBoss S600 is possible but data has been limited for the purpose of this demonstration. In addition all of the alarm status information is viewable. Flow Rate alarm thresholds can be downloaded to the FloBoss S600; the Alarms can also be accepted from the browser.
The Webspring server is communicating with the FloBoss S600 via the integral FloBoss S600 10baseT port using the Modbus TCP/IP protocol. Although this demonstration is a simple flow measurement configuration, Webspring can communicate with a complete metering system providing individual stream information and station information.
The information displayed in this demonstration is Gross and Net Volume, Flow Rate, Inlet Temperature and Inlet Pressure. A chart shows the Flow Rate in graphical form along with the high and low alarm thresholds obtained directly from the FloBoss S600. The alarms in this demonstration are shown as a graphic annunciator mimicking the alarm status of the FloBoss S600.
The implications of Webspring technology are wide. The data from a Webspring server can be viewed using Windows, Macintosh, or Unix browsers. PDA’s using Palm or Windows CE technology are also able to access data and interact. Ambrit is currently working with Epson’s ND3000 Touchscreen intranet terminal to provide secure web based interactive access to remote instrumentation with flat touchscreen interaction.
To emphasise the portability of data access, Webspring can be used to display variables and alarm events on W.A.P. telephone technology.
