Why do automation manufacturers use pcb proofing

Time:2020-11-24 Preview:106

In the system that describes the behavior of the control process, the data structure of the stored process management and control information is called pcb proofing. It is a part of the process object and the most important record data of the operating system. For process management and control, the most important data structure is that each process has a pcb proofing process, and the entire process is run when the process is generated, until the PCB is generated and the process is cancelled. The pcb proofing records all the information required by the operating system to describe the current state of the process is the control process behavior of pcb proofing.


As a basic unit, pcb proofing can independently execute programs that cannot be executed independently in multiple program environments, including data, of course. PCB proofing is a process that can be executed simultaneously with other processes. This is a process based on PCB proofing, or a process that controls and manages concurrent running. The pcb proofing is a static description of the process, which consists of three parts: PCB, associated program segments and a data structure set in which the program segments are run. The function of pcb proofing is to create a basic unit that can independently execute programs that cannot be executed independently in multiple program environments, and create a process that can be executed simultaneously with other processes. Is to be done. The program segment is the program code segment that can be executed by the CPU by the process scheduler of the process, and the data segment of the process is the original data processed by the program corresponding to the process, or the intermediate or final value generated after the program is executed. Some of this may also be data, which is inaccurate.


Throughout the life cycle of the process, the system always uses pcb proofing to control the process. In other words, pcb proofing is being processed, because the system is based on the PCB of the process and knows the existence of the process instead of just displaying other things. This is undoubtedly a very good choice for our pcb proofing. The correctness of the process makes the stability and accuracy of pcb proofing, which is why so many automation manufacturers choose pcb proofing.
