A monitoring system is developed by means of simple boiler intake, effluent and heating processes. In the process of water level change, it can monitor, alarm, real-time trends and report statistics, and other simple operations. The related functional modules are described below

  Real time monitoring: monitoring the process animation of the whole boiler system;

  Real time trends: the trend of real-time changes in water levels is monitored through real-time curves;

  Historical trends: monitor the trend of historical changes in water level by using historical curves, tool operations, and custom function query operations;

  Alarm query: for the alarm box (history, alarm, query) controls the operation of water level alarm inquiries;

  Report query: for the statements of custom queries and related basic functions of the application of processing;

  Operating records: mainly to facilitate the administrator through the recording box, to see the user's history of software operations;

The SCADA is a Supervisory Control and Data Acquisition system.It is based on computer manufacturing process control and scheduling automation system;it can monitor and control the field running equipment in order to realize data acquisition, equipment control, measurement, parameter adjustment and all kinds of signal alarm, generating charts, and other functions. SCADA plays an important role on improving the reliability of industrial production, dispatching control, security, economic benefit and working efficiency, reducing staff burden and reducing Labour and realizing automation and modernization.

IO communication refers to the DIAView SCADA connects to the device through the specific communication protocol for data acquisition and transmission, high reliability, stability, real-time and powerful data processing ability.

The variable dictionary is a collection manager for all the engineering variables in the DIAView system, unifying and centralizing all the variables in the project. Variables group, variables, and variables can be created in a variable dictionary, as well as adding, deleting, copying, pasting, cutting, importing, and exporting variables.

Graphical interface development is to ground the field facilities, equipment, structure, instruments and meters and other vividly drawn in the window of the DIAView SCADA, form industrial field simulation; Can also be configured to connect field devices, instruments and meters and other data acquisition equipment, data real-time display in the window, convenient staff real-time view field status; It can also control the on-site equipment by using analog device switches and controllers in the operating window interface.

Mainly from the following several aspects to explain and demonstrate operation: real time curve, history curve, X-Y curve, the custom, 3D pie chart and pie chart, histogram and history histogram, reports and other extension controls.

Alarm is collected data to the system beyond the alert when the value of a reminder, in the process of production in order to achieve risk early warning and prevention of equipment failure, alarm in the industrial automation control system plays an irreplaceable role in system security control.

Provides the operation mode of 'class excel' reporting tool, the common production report (daily report, monthly report and annual report, etc.), can also be flexible manufacture all kinds of complicated format report, complete the real-time, historical and statistical data query, display, print, and output. The report not only shows the data of the real-time historical database, but also can be accessed and queried with typical relational databases such as Mysql, SQL Server, Oracel, and Access

Graphics library contains DIAView SCADA with a collection of commonly used graphics model and the user set custom graphics, such as container indicating instrument, button switch, valve, pump motor fan, such as graphics, users can create their own common graphic model and added to the graphics library.

Animation, it is to point to by establishing a picture element and the corresponding relationship between internal variables, the image data from the attribute of the element with the dynamic change, the real present industrial field dynamic scene. For example, the pipe in the picture simulates the flow of liquid, the real-time variation of the instrument and instrument data, the motor rotation, the flashing of the alarm lamp and so on.

An event is an operation that can be identified and responded to by a graphical object, divided into system events and user events. The events in the DIAView SCADA are typically user events, which are the user's actions on various graphical objects on the window to drive a graphical control to perform a function.

User authority the user use DIAView SCADA of operation and the control permissions, contains a 'security zone' and 'user', through the user permission management can ensure the safe and reliable operation and stability of engineering operation, avoid the user in the wrong operation in the project development and operation, unauthorized, illegal change project Settings, operation and so on.

Operation variable to the user in the process of operation change engineering information to keep records of variables, and events related to track record for system variables by the user operation. The saved record information includes the variable name, the change time, the value of the variable before and after the change, user information, and so on. DIAView SCADA for real-time display and control production and site operation state, will establish many variables associated with field devices for data interaction, and these variables are constantly update change, in order to save the important production data, the statistical analysis of data to see the production status and system operation information, to improve production efficiency and quality of the major objectives, and optimizing system, require the system to the variable data in the running process for recording, realizing the function of the variables is called records.

In industrial production, the formula method is provided for the product ingredients and materials proportion of prescription, in DIAView SCADA is variable in the process of production corresponds to the set of parameter values.

The user program, which is the user's own special function, can improve and expand the function of DIAView SCADA. Users can write programs in engineering, flexible DIAView calls and control SCADA in all kinds of graphic objects, command, such as resources, improve and optimize the system working process, improve the execution efficiency.

The database access provides the user access to the external database in the DIAView program, querying, and editing the data in the database. The user can configure the data in the database at run time as long as the database connection is configured in the database access. The currently supported database types are: SQLServe, SQLServer Compact, Oracle.

In the DIAView SCADA, the main function of the project configuration is to configure the database running the environment, the shortcut keys in the running environment, and the images that are opened when the project is running. DIAView SCADA fully functional and strong, but the needs of customers of different function, some functions are based on customer needs additional customization, DIAView SCADA can root through the script editor to write programs to complete some special tasks and functions.
