(3) animation. That set of color, size, graphics, visibility, flashing the position and effect of animation attributes and real-time graphics object database definition of data objects, and establish corresponding connections with the data object value change to flooding
Dynamic graphical object, make the system in the process of operation, image is clear, the animation intuitionistic description of the controlled object outside scene state changes, especially the visual display fault segment.
(4) write control process. For complex engineering control system with conventional configuration, only to the corresponding methods may control and computing tasks, it needs to be provided by the Basic similar MCGS built-in programming language, prepare all kinds of specific flow control procedure and operating procedures, which helps to optimize the control process.
(5) and external PLC linkage testing equipment. According to the control system adopted PLC type and characteristics, the first set of equipment related attributes, Set the input and output equipment configuration of PLC system data object channel and the corresponding relations between the real-time database system, namely, to establish the input and output port with PLC system can make the connection, read data and control devices external external devices working condition, Finally, the control system configuration Settings and debugging inspectors correctly, hardware whether programming, computer graphics and animation shows whether the actual movement synchronization etc. Upon completion of the project's configuration and test site programming project each part of work, can realize the PLC and the controlled object working condition of real-time monitoring of computer graphics, computer graphics functions of the simulation flow control interface with the actual production movement synchronization. When the site failure or abnormality, PC monitor interface graphical elements of the corresponding with eye-catching colors will sparkle effect etc, the visual image, sound and a fault alarm, This helps to personnel timely grate troubleshooting or necessary remote control, thus ensuring the intervention of PLC control system, safe and reliable operation.
2 RS485 serial communication data exchange
In situ measurement unit, with the upper level and RS485 downstream water, wool head, unit LanWuShan differential pressure monitoring system for hydropower station, the dam system such as pressure, so as to realize the sharing data. RS: 485 communications: -
RS - 485 communication and serial interface communication mode. Refers to computer through the rs-five 484 international standard agreement with serial connection and single equipment (controller) communication mode.
The farthest distance: communication equipment to computer attachment theory of distance is 1200 m, suggested control in 800 meters, can control in 300 meters within the best effect. If the distance, can choose 485 super-long Repeaters (extended) (please to professional production companies to buy, the converter is placed Repeaters, or in the bus started among, please refer to the relevant manufacturer specifications.) Choose Repeaters theory can be extended to 3000 meters.
Baud Rate of communications (Baud Rate) : the default Rate of 9600 BPS, common are still 12, 24, 48, 19200 38400, etc. Baud rate, transmission speeds faster, but shorter, the transmission distance with the anti-interference ability.
Load quantity: namely a 485 bus can bring many devices, this depends on the controller of communications chips and 485 switch communications chips are usually the selection, 32, 64, 128 sets, 256 sets options, this is the theory of digital and practical application, according to the environmental factors such as the distance, communications, load quantity index number reach.
General desktop to take 1-2 serial socket (9 needle plug of male head with needle, needle with the female head).
Serial connecting with the general standard: is 3 meters.
