2. How iSCADA works
A Gateway acquires data (failure events or measurements like temperature) from appliances or sensors and transmits them to a server on the Internet.
Authorized users access data in real time from any PC with an Internet connection
When a pre-programmed exception occurs, users automatically receive an SMS or .

5. iSCADA for Academicians – Measure, Analyze, Collaborate
Measure real world parameters remotely in real time Perform data acquisition for scientific investigations or educational experiments remotely. Collaborate and analyze data over the internet with multiple investigators in real time.

6. iSCADA in the laboratory– Automatic or Manual sampling
Automatic sampling over extended period of time Sampling conditions can be changed remotely any time throughout an experiment Unlike standalone data loggers, iSCADA offers virtually unlimited storage capabilities.
Manual sampling Watch the data remotely as measurements are made in real time.

7. iSCADA at the field– Full feature data logger at remote sites
Bring the laboratory to your site or Bring the site to your desktop Fully end-to-end Internet-based data logging solution makes this a reality.
Wide connectivity Options Ethernet - LAN PSTN - Terrestrial Dialup GSM - Mobile Dialup GPRS – Wireless always ON UHF – Radio Modems ACeS – Satellite Dialup MPDS – Satellite ISDN VSAT – Satellite Broadband

9. iSCADA Benefits
Cost of data transmission Since all communications between devices, server and users are Internet based, this translates into the lowest cost compared to all other systems. Devices can be placed anywhere in the world, and users can seamlessly communicate with their devices from any Internet connection. Consolidated information  Since all data is stored in a central database in the Internet, users have global access to consolidated data from many systems or locations. In point-to-point systems, data resides in a particular physical location (typically a control room), and access is restricted.  Fast & Easy Deployment  User friendly hardware interfaces with a wide range of legacy appliances and transducers. Managed services eliminate cost and complexities of owning and maintaining server and software. Universally accepted User Interface Web-based solutions like iSCADA have a universally accepted, familiar and user-friendly Graphical User Interface (GUI). This takes the complexities out of sophisticated engineering solutions, and places information in the hands of managers and other decision makers. It also flattens the learning curve for engineers.
