the form of its components is an integrated software platform components from a number of procedures.
Typical components which must include the following:
(1) Program Manager
(2) interface development process
(3) graphical interface to run programs
(4) real-time database system configuration process
(5) real-time database system operating procedures
(6) I / O driver
Expansion of optional components include:
Generic database interface (ODBC interface) configuration procedures
Generic database interface software component used to complete the configuration of real-time database with general-purpose database (eg Oracle, Sybase, Foxpro, DB2, Infomix, SQL Server, etc.) of the Internet, the realization of two-way data exchange, common database can be read by both real-time data historical data can be read; real-time database is also available from Universal Database in real-time data read. Generic database interface (ODBC interface) environment configuration for the specified database to the exchange of common database structure, field names and attributes, the time section, the sampling cycle, and real-time database field corresponding to the relationship between data.本文来自优~文\论|文/网，

Generic database interface (ODBC interface) to run programs
Have a common configuration database connection has been put into computer memory, in accordance with the pre-specified sampling cycle time of the provisions of section configuration of the database structure in accordance with established common database and real-time data connectivity between databases.
Strategy (control program) to edit the configuration process
Policy Editor / generation component is to achieve low-cost PC as the center of the core monitoring software, has a strong logic, arithmetic operations and a wealth of control algorithms. Policy Editor / generation component to IEC-1131-3 standard provides a standard for user programming environment, there are four kinds of programming by: ladder diagram, structured programming language, command mnemonic, modular function blocks. Users are generally accustomed to the use of modular functional blocks, according to the configuration control program, after the end of the contents of the system configuration will be saved and the contents of the configuration syntax checker, compiler.
Compiler to generate code that is the goal of the strategy with the same graphical interface running on a computer can also be downloaded (Download) to the target device (such as PC/104, Windows CE system, such as PC-Based Equipment) run.
Strategy for running the program
Target system configuration strategies are put into computer memory and the target of a variety of data, data-processing tasks, while the completion of the database and real-time data exchange.
Practical components of the communication process
