Before the development of ACS (Automated Systems Administration) Customer makes a number of conditions, among which the role played by the correct and convenient withdrawal of technological information, intuitive and logical equipment controls. On the one hand, the information should be readily accessible. On the other hand, for large scale production to withdraw all indicators and controls for quick access is not always possible. For example, due to the small size of control panel, or premises ...

Come to the aid of modern means of automation. The evolution of the software industry has led to a specific class of programs, a sort of electronic equivalent of "classical control panels - SCADA-systems.

-

The relatively small objects instead of SCADA-system is sufficient to establish a control board operator panel:

Program visualization and control in most panels are classified as HMI class, that is, represent a simplified version of the SCADA.

The panels vary from simple two-color text to large color graphics. Entry information can be both with the buttons on the front panel or directly from the display (touch screen). And with the development of modern manufacturing techniques, color, touch panel, average size dropped in price considerably. For example, a panel of DOP-B05S100 company DELTA electronics, diagonal 5.6 "at the beginning of 2011 is only 460 $, and two-color operator panel TP04G-BL-C - $ 149
Quite a few PLC manufacturers release their operator panel, and many of these panels can not only work with "their" equipment.

SCADA is a software package, which includes specialized software modules: module design, module runtime (Runtime), communication module, the module data archival module, emergency communications, administration module.

Consider a general purpose core modules SCADA system.

Module Development

Design module, or another tool environment designed specifically for developing a working draft. Largely thanks to the concept of SCADA, the basis of which is partially automated design, solve a number of problems - the minimization of project development time of ACS and direct cash cost of their creation, ease of further extensions and perenastroek.

Module runtime (Runtime)

Technological process on the monitor screen is represented as a mimic, and the parameters of the technological process can be displayed in real time in digital form, and through animated images, change color, size, position, appearance - depending on the state of the corresponding parameter. Necessary elements are active mimic that allows the module to the runtime to handle operator input commands and to transfer their equipment.

Module Backup

Archival information in the mode of execution can be represented on the screen of a workstation in the form of tables, graphs, or, for example, messages. The module provides access to archive data for any time period during which conducted archiving, enables creation and printing the reports. Some SCADA systems allow you to export data from archives in the formats of external systems (MS Access, MS Excel), as well as record in the archives of the staff (up to switch between windows).

Module Alarm

Produces the detection of emergency events associated with the controlled process and the functioning of software and hardware control systems. When this module notifies the operating and maintenance personnel, issuing reports on the accident and sound. Operator is given the ability to customize features and criteria for the detection of emergency events. Capabilities and backup emergency events.

Administration module

With this module, create user accounts and developers SCADA system and using a password system privilege separation user access to the monitoring and control.

Module Communications

Under this concept can combine several different functions. They all share a common purpose designation - links this SCADA system with external objects. The most common communication is the data source connection. The data source can be directly PLC, SCADA, if the driver has and the opportunity to work directly. But more often between the data source and SCADA uses an intermediate element - OPC server. OPC Specification is a standard that enables independent software developers and hardware vendors to create products compatible with each other. Introduction This specification facilitates the creation of ASU from diverse components as well as rare a developer of SCADA systems quickly released the driver on the existing diversity of PLC.

Another function of the communications module can be considered an organization architecture the server and client. " This architecture allows to increase the number of workstations without increasing the load on the link to the PLC, since all data received and sent by the stations, customers are allocated a server station. The individual stations can be connected to the network without any impact on the work of the server station. An additional argument in favor of such an architecture can serve as a policy of licensing of some SCADA. Price Architecture "server and client can be an order of magnitude below the price of a multi-user architecture, and the number of customers in some of the licenses is unlimited.

Also to the functions of communication module may include intensifying recent popularity of the technology «web-client." The technology is simple: SCADA system is connected to the Internet and works as a web-server. Through the Internet, you can anywhere in the world to observe the process and even control it using any standard web-browser. Unfortunately, not all SCADA systems support this technology.
