In the newly designed program, since the output has only two channels, only the first two bits in the sixteen-bit shift register are used, and the two bits directly drive the output relay, so only the first two bits can be controlled in accordance with the logical relationship. And only use the shift instruction to trigger the first register. The program is greatly simplified and the purpose of optimization is achieved. The pulse command of the pulse command is that when the input signal of the control pulse command is turned off to on (signal leading edge), the command emits a positive pulse having a width of one scan period.
In the shearing process, manual shearing requires a minimum time interval of 0.25 between the two shearing plates. In the newly designed program, we use the pulse command to trigger the shift instruction. The purpose is to trigger the shift and immediately remove the trigger signal so that the shift command can be triggered again within the required time to achieve the manual cutting process. Claim. Therefore, using this instruction is a relatively simple method.
In the original procedure, this was done by the interlocking of auxiliary relays. This increases the number of instructions. Through the comparison of the above two actual procedures, we can see that although the control objects are the same, the conditions, methods and requirements of the output are the same, but the complexity of the two programs is quite different. Therefore, when designing the program, we must not only ensure the correct requirements and logical relationships of various processes. The program should also be optimized based on the characteristics of the programmable controller and the performance of various instructions. This is especially important in the preparation of large and medium-sized processes and complex process control procedures.
(Finish)
It is a main Plasticizer used mostly in plastic processing and has excellent comprehensive properties.
It is widely used in the processing of polyvinyl chloride, vinyl chloride copolymer and cellulose Resin, and in the manufacture of thin films, artificial leather, wire and cable sheets, plates, mouldings, plasticizers, etc.
This product can also be used as a softener for synthetic rubber such as NBR. It can improve the resilience of products, reduce the compression permanent deformation, and has no effect on vulcanization of rubber.
80%~90% of DOP is used in the PVC industry. Others are used in rubber, recycled plastics, lubricants, adhesives, coatings, macromolecule additives, softeners for printing ink and capacitor oils. They can also be used in polyvinyl acetate, polyvinylidene chloride and so on.
