Scada historian data analysis

Gas companies make every effort in order to achieve RTBI as a viable advantage. The business IT communications, business requests and SCADA and PCS are congregating. Joining the union of this communication is the amplified threat of cyber-rate in the SCADA and PC environments.

The SCADA together with the Process Control Security dispute has to be assessed based upon the objective, this is to find out whether the installations is for securing the present installation or to install a whole new system.

With the speedy expansion of the industrial fields during the 80's as well as the 90's, most of the installations as the time were not designed with security in mind. Driven by the ability to work as one together with the present time commerce acumen the installations of the 80's and 90's have overtime become more incorporated with the business IT set of connections.

The brain of SCADA system lies in Remote Terminal Units (also termed as RTU). Remote terminal units are composed of logic converters which can be programmed easily. Remote terminal unit is generally set as per the requirements, but mostly RTU requires human intervention in case of emergency or any extreme conditions. But in general, most of SCADA system behaves as closed loop systems thus require minimal human intervention.

One of key features about SCADA systems is their ability of real time monitoring of entire system. This is accomplished by data acquisitions from sensors viz meter reading, status of sensor etc that are sent to central system at regular time period depending upon the system. Along with data acquisition another function performed by SCADA system is to display the data collected from various sensors in human readable format so that any time human can intervene as the need arises.

Scada in the gas industry

Foreign Countries gas operations face a number of important challenges, for example remote assets, unreliable communications, high costing and implications of safety as to having people overseas that face the challenge on a daily basis. The most complex of challenges that are faced in the gas industry would have to be the accounting area together with the multiple tax as well as royalty regimes during one operation.

The Gas Industry is also faced with a combination of regulatory, environmental, political as well as economic situations.

The Security Challenge; may be, occurrence of cyber-attack or intrusion, this may be accidental or intentional but has however increased over the past few years. The preservation of the honor of the gas industry on a global scale is fundamental, for the continuation of ongoing business, safety of the public, the interest of national security as well as both the National and Global economy.
