The theory of PLC programming is important. Without theoretical preparation or guidance in this regard, simple problems are easy to solve only by groping in practice. It’s not easy to deal with complicated ones. Not only is it impossible to start, but it takes a lot of time and energy. It is also difficult to compile programs with high efficiency and high quality. It is often twice the result with half the effort.
However, the specific practice of programming and the knowledge or skills gained from this practice, namely experience, are also important. Without experience and only theory, we can neither deeply understand theory nor flexibly apply it. This is just like learning mathematics. If you only know some theorems or remember some formulas without corresponding practice, you will definitely not learn well. Needless to say, any theory is only a summary of experience, and in the final analysis, it comes from practice.
1. Experience accumulation
It is important to have experience of others and own. The former depends on careful study, while the latter depends on careful accumulation, which requires a certain amount of time and necessary energy.
Others’ experiences have been published in books or magazines. Some learn from others carefully, but most of them are my own experience. All examples have been tested by me and proved to be feasible. I think it will be the same in other books or magazines. So it is necessary to learn the experience of Yang Gong.
The experience of your colleagues is also worth learning. This experience is very close to you and easy to learn from.
Your own experience is important. We should accumulate our own experience in our own practice. At the same time, it is good to learn from other people’s experience, but also to do some tests in person, so that you can have similar experience, and then turn these experiences into your own. This is also an important accumulation of my own experience.
There are also some failed experiences, which are often not open to the public, but these experiences also need to be learned and accumulated.
The accumulation of experience should be recorded with your own brain, but also with your computer. It is good to make some classification and establish a self-use program library for reference at any time.
2. Experience sublimation
Experience has yet to be sublimated. There are three levels of sublimation:
The lower level is to build a typical program library for future use. If the program is complex, some function blocks or subprograms can also be built for future reference.
Secondly, effective algorithms should be summarized. For example, single button start and stop program library.
The high-level sublimation is to raise the experience to the theoretical level and make contributions to enrich the PLC programming theory. I think that with the popularization and improvement of PLC use, there will be more and more PLC programming theories that are sublimated from experience and can be used to guide practice.
3. Experience application
Experience accumulation and experience sublimation are all for application. There are three aspects of experience application:
1) Use as an engineering template. When designing a new system, select one or several successful projects similar to the current design projects as a template for design. This can not only reduce the workload of design, but also increase the success rate of design. This is also a major benefit of information reuse.
2) It is used as a reference for program design. When no successful project can be used as a model, there is still a considerable part of control logic in the new design logic, which can be used or borrowed from the existing typical logic, which can also reduce the workload of design and increase the success rate of design.
3) It is used as a reference for algorithm design. When there is neither a template to reference nor a model to use, some successful algorithms in the past can also be used.
Experience is valuable, but experience, especially personal experience, is always limited. Therefore, the application of experience should also be combined with programming theory.
