A SCADA System Assessment
A Pre-SCADA System AssessmentBy Randy DennisonIntroductionSupervisory Control and Data Acquisition (SCADA) system is a control process that allows a site operator to control processes distributed among various locations and a remote control. These systems can be used to control and land, air or water pollution control equipment, or slightly more than manufacturing process.A well designed SCADA system saves time and money by eliminating the need for service personnel to visit each site for inspection, data collection, monitoring / recording or make changes.
Real-time monitoring, system modifications, troubleshooting, material life and increased production of automated reports are just some of the benefits of SCADA technology continues to advance systems.As today, these systems will be the standard process control operation. But hundreds of suppliers of systems available today, we have a choice to join and why? Choose a system supplier to design a system applicable to the needs of an operator can be overwhelming, the task of confusion. With little or no knowledge of SCADA and telemetry systems and an incomplete pre-system assessment, decisions can include costly mistakes.
Too often, decisions are based on: Cijena: Quality of system components and the production of May suffer when vendors lowest bid to win the contract. The seller may then indiscriminately cut costs to make profit.Proprietary equipment – If a private, secure protocol device is installed in the system, the customer may be forced to pay high prices and the possibility of future problems caused by the integration equipment or components obsolete front, closure of businesses and the lack of support when it's time for equipment or custom repair.
Excessively complex: If the SCADA system is too difficult to understand, manage and support, the only recourse is costly training and / or services for purchase service.Years not always guarantee fast and professional experience or knowledge of the know-how: There are many reliable suppliers of SCADA, with years of experience and professional expertise, systems designed for large or too expensive. Experience and knowledge are important, but only as a starting point when choosing a vendor.Sales persons and / or flashy marketing: sales and marketing strategies are designed to deliver effective high mind.
Preventing attracted or driven to a purchase. Center and a good decision based on all factors affecting performance.These optimum system and other costly mistakes can be avoided through knowledge, understanding and careful evaluation. Some will consider only the tables A and B of this section. Others, with little or no knowledge of SCADA systems, you must familiarize yourself with more substantial information.A SCADA brief history began in 1960 as an electronic / transmission / output between a master station and remote station.
The post of master receive data through a telemetry network and then store the data on the mainframe computers.In early 1970, Distributed Control System (DCS) were developed to control the various subsystems and remote areas in the 1980s with the development of micro – computers, process control could be distributed remote sites. Additional development could DCS using programmable logic controllers (PLC), the ability to monitor the sites without the supervision of a master.In late 1990, SCADA systems are built with electric systems and DCS were adjusted some control patented integrated designer .
But the Internet is increasingly used as a communication tool, SCADA and telemetry systems are automated using software with certain portals to download information or control system SCADA process.Engineered today not only the shipping process, but are also used for measurement, forecasting, billing, analysis and planning. Today, the SCADA system must respond to a new level of automation and control, while the interface with legacy devices of yesterday remain flexible enough to adapt to the requirement developments.
Whether tomorrow is a new management system or more, it is important
