Functions of configuration software

Configuration software refers to some special software used for data acquisition and process control, which is the software platform and development environment of monitoring level of automatic control system. It can provide a good user development interface and simple use method in flexible and diverse configuration mode (rather than programming mode), and solve the universality problem of the control system. Its preset software module can easily realize and complete the function of monitoring layer, and can support computers and I/O products of various hardware manufacturers at the same time. Combined with highly reliable industrial computer and network system, all interfaces of software and hardware can be provided to the control layer and management layer for system integration.

Configuration software usually has the following functions:

(1) Powerful interface display configuration function. At present, most industrial control configuration software runs in Windows environment. By making full use of the graphical functions of Windows to improve the beautiful interface, visual M-style interface and rich toolbars, operators can directly enter the development state, saving time. Rich graphical controls and working condition libraries not only provide the required components, but also can be used as a guide for interface making. Provide users with rich drawing tools, which can draw various industrial interfaces at will and edit them at will, freeing developers from the heavy interface design. Implicit, flashing, moving and other rich animation connection methods make the interface vivid and intuitive.

(2) Good openness. Socialized mass production makes it impossible for all the software and hardware of the system to come from the products of one company. Heterogeneity is one of the main characteristics of today's control system. Openness means that configuration software can be interconnected with various communication protocols and support various hardware devices. Openness is an important index to measure the quality of a configuration software.

The configuration software should be able to communicate with the bottom data acquisition equipment downwards and with the management upwards, so as to realize two-way communication between the upper computer and the lower computer.

(3) Rich functional modules. Provide rich control function library to meet the user's measurement and control requirements and field requirements. Using various functional modules, real-time monitoring can produce functional reports, display historical curves, real-time curves, remind alarms and other functions, which makes the system have a good man-machine interface and easy to operate. The system can be applied to single-machine centralized control and DCS decentralized control, and can also be used as a remote measurement and control system with remote communication function.

(4) A powerful database. Equipped with real-time database, it can store all kinds of data, such as analog quantity, discrete quantity and character type. , and realize data exchange with external devices.

(5) Programmable command language. There is a programmable command language that enables users to write programs according to their own needs and enhance the graphical interface.

(6) Careful system safety precautions give different operators different operating rights to ensure the safe and reliable operation of the whole system.

(7) Analog function. The powerful simulation function enables the system to be designed in parallel, thus shortening the development cycle.
