When we select PLC as a controller for the construction of industrial automation production line, we should go through the following process, which is briefly described below:
1. First of all, the demand side, that is, Party A, needs to tell Party B what the purpose is what it wants to achieve and what kind of effect it wants to finish
2. Party B shall formulate a corresponding solution plan after clarifying Party A's needs
3. At the end of the plan, if Party A has no objection, it will start to determine the IO points and varieties required by the project
4. After knowing the variety of IO points, select the appropriate PLC, remember to have a certain functional redundancy to prevent accidents
5. After the selection of PLC hardware, start to write the control program according to the solution plan
6. After the control program is written, the practice of the online test begins
7. There is no problem with the test, deliver it to Party A for use, if there is a problem, modify the program content, and wire the test from scratch until Party A satisfies it
The above is the general process of PLC projects, we also do PLC at home, and also receive PLC custom projects
