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.
