Configuration technology in the application of the PLC control mill

Abstract: this article through the configuration technology and the application of PLC controller in the pulverizer, for example, this paper introduces the implementation between the kingview and PLC used in combination, the design and monitor the operation of the key steps in precise instructions, and the specific application process gave a clear explanation. In addition, our example application methods and ideas in application engineering or project teaching has good guidance and reference value. Quote due to the current PLC has a strong advantage, reliable performance and remarkable effect, is widely applied in all walks of life control in the field of automation and modernization, in addition because of configuration technology and its combination with PLC control application, the application of PLC technology control field to develop in the direction of faster and at a deeper level. 1 mill pulverizer is a kind of the larger size of the solid material processed into smaller size of the processing machinery, according to its types mainly can be divided into the primary crusher, crushing machine, fine grinding machine, ultrafine grinding machine, the main processing methods of impact pressure rolling type, cut type, type, grinding type, such as four, in addition to ensure the safety of the mill production and reliable, its crushing device usually adopts hydraulic motor to drive. The mill is mainly used in the metallurgy, building materials, chemical industry, mines and other product materials for processing and production of granular or powder. 2 configuration combined with PLC controller program design first according to the working process of the controlled object, use the accused company in Beijing 'kingview 6. 52 'version of the software to create the corresponding monitoring demonstration picture; Second picture for the monitoring of each pixel in the variable parameters setting, special attention should be paid to the pixels of the type name must register with the design procedure of the I/O device register type name is the same, and the figure and the corresponding variable parameters to connect animation; Again kingview and PLC communication baud rate to 9600, choose way of odd parity and the check digit for seven, through RS232 interface cable and mitsubishi PLC to build physical connection; Finally using FXGPWIN programming software to transfer the program designed to FX2N - 48 Mr Type of PLC, then set the operation mode of the PLC to running state, then create the monitoring picture of transition to the VIEW mode, by clicking on the images of the corresponding button or switch can realize the real-time monitoring and control of the controlled system operation. 3 application example 3. 1 mill the summary of working process of the hydraulic motor drives the grinding device movement, and then the hydraulic cylinder will stretch out materials to promote A crushing cavity, after pushing cylinder A return to the in situ, such as add the material continues to stretch out. Shredded material into the die slot, when the material to set in the die slot weight when they stop feeding the hydraulic cylinder of A stop, the hydraulic cylinder B out for material is compressed, compressed after the completion of the cylinder B back in situ, and then the hydraulic cylinder C reached out to pull material block out die slot, and then return to the in situ hydraulic cylinder cylinder C will continue to stretch out A feed, so cycle. 3. 2 pulverizer control program design according to the actual control requirements of mill and the working process and the basic requirements and steps of PLC program design, design the corresponding PLC control program. In addition to better for program design and understanding, I/O components of the program of the actual object made a special annotation instructions, and procedure in the X and Y some actual label element meaning is said to connect the input and output components. 3. 3 the use of configuration software. 3. 3. 1 according to the operation process of the configuration software, configuration wang xin engineering was established, and then complete the equipment selection and configuration of the new according to the configuration of wang xin engineering installation prompt in its equipment column selection, the selection of PLC of mitsubishi FX2 series PLC programming and communication with port COM1, the means and the actual connection is established, the PLC according to the installation prompts to complete other Settings and select content. 3. 3. 2 according to the work and control process of the mill, design and create its configuration monitoring menu or from the kingview gallery in the element names in the process of selection and the control of corresponding pixels, and then to choose figure element of the location arrangement, specific design picture as shown in figure 1. Figure element in this picture said only corresponds to the actual working status and process of components, structure and physical connection does not represent the actual component, so as to improve the flexibility of the frame design. 3. 3. 3 according to the name of the I/O devices in the design process and the label, this picture of the pixels in the variable parameter setting and selection for each pixel defining a corresponding variable parameter. In addition to variable parameters of each pixel corresponding animation connection, so the figure element in this picture the VIEW mode to manipulate it. 3. 4 application implementation at the completion of the above content and other related preparations, according to the design of PLC and kingview communication connection to be established and other parameters are set, then the design of PLC control program written to the machine, and then set the operation mode of the PLC to running state, then transfer configuration monitoring picture to VIEW mode ( Note: PLC controller after the operation can't use its own monitoring mode, monitoring pixels of the image will be invalid) So that it can monitoring and control on the working process of the mill for operation.
Maintaining plc controller price is not as easy as it may seem. You have to do plenty of important tasks. So cruel is the truth unless you've got a to help you.
Shenzhen Coolmay Technology Co., Ltd. ’s goal is to achieve customer satisfaction through excellence in design, supply chain management, manufacturing and repair solutions.
The programmable control systems plc manufacturers is an all-servo system capable of storing hundreds of plc controller price process parameters to provide custom programmable control systems profiles for each plc controller price type and programmable control systems configuration.
There's the area of manufacturing plc manufacturers that's becoming very important. If you can create those things, you build this closed bond.
[拓展名称] include a great variety of devices with a wide range of complexity: from simple plc controller price used since prehistoric times to the complex of modern mechanized programmable control systems.
