4.5 Run the server to serial port software zwsvr2ck.exe Set the IP, port number, and terminal number according to Figure 7 to be 10000000008. Just start the server and it will display online after startup, as shown in Figure 10. Figure 10 Start the server 4.6 DVP-10SX Settings Mainly to set the PLC 232 programming port baud rate setting and the same DTU setting 115200, 8, 0, 1, both use RTU mode modbus. Download program. Figure 11 PLC program 4.7 DVP-10SX online monitoring via wireless communication PLC and DTU are connected through 232 serial cable. Please pay attention to check wiring method 2-3-5, RX-TX cross docking. Open the PLC programming software WPLSOFT2.12 and select "Communication Settings" and confirm according to Figure 9. Then select online mode to start communication. The data of the PLC programming software is sent out through the virtual serial port, and then the server forwarding program converts the data of the virtual serial port into TCP/IP, and the DTU receives the data and converts it into 232 to the PLC. Because our PLC supports the standard MODBUS protocol, other configuration software can directly communicate with our PLC in this way as long as it supports the standard modbus protocol. As shown in Figure 12. Figure 12 Communication settings 5 Application Delta PLC uses the standard modbus protocol, which is compatible with a wide range of devices and is widely used. In this case, after using this scheme on the woodworking equipment, the user can conveniently realize the wireless communication function of the monitoring room PC and the field device, achieving the purpose of real-time monitoring, remote operation, convenience and reliability. 6 Conclusion According to the technical requirements of customer equipment, the woodworking machinery remote control system combines Delta PLC, DTU and other automation control products to develop a stable and reliable remote monitoring system for customers. It has been fully recognized by customers and users, and once again proved that Zhongda Dentsu is a trusted partner for customers. The operation practice shows that the system performance is stable, safe and reliable, and cost-effective, which is worthy of reference and promotion by industry peers. ã€references】 [1] Delta DVP-PLC Application Technical Manual, Delta Internal Information 2007 [2] ZWDTU Application Technical Manual, Internal Information 2007 [3] "Communication Principles", 3rd edition, Beijing University of Posts and Telecommunications Press, 2008, Zhou Yipan, etc. Industrial applications editor broadcast
Whetstone sintered corundum (ruby) : A kind of microcrystalline corundum product sintered at high temperature. It has a compact and delicate structure and high hardness and strength.
The products are rosy red. The products are small grinding wheel type whetstone, standard type whetstone and grinding head type whetstone. When grinding the workpiece, it can maintain sharp edge and stable geometry for a long time.
It is suitable for forming and grinding of instrument industry, precision parts, micro cutting tools, tools and precision abrasive tools, etc. The precision surface roughness of machining can reach about 0.05μm.
Product SPECIFICATIONS: flat sand wheel whetstone with diameter less than 100 for small grinding wheel type, whetstone with various geometric shapes less than 200*50*25 for standard type, whetstone with diameter less than 25 for grinding head type.
Grinding method
About diamond grinding paste, particle size from W40 to W0.5. W40 is the coarsest, with a large amount of grinding, and W0.5 is the smallest. It is used for polishing, and it does not anneal, and it can also grind the hard knife.
Method of use:
The coarse W40 abrasive paste applied to borotartar can accelerate and increase the grinding amount without annealing.
Then, AFTER the rough grinding paste on the knife is cleaned, W0.5 grinding paste is applied to the ruby or natural jade for polishing, and the effect thrown out is a mirror.
Green silicon carbide, white corundum, brown corundum of these three kinds of whetstone hardness is not enough, coupled with a little coarse particle size, easy to grind out the cross, and the other three kinds of whetstone in polishing, grinding will not annealing.
If the particle size is greater than 1000, there is no difference. It mainly depends on the grinding paste used. When the grinding paste of W1.5 is applied to the ruby with 1000 mesh, its grinding effect is the effect of the grinding paste of W1.5, that is, the effect of the whetstone with 2500 particle size
