What performance does the industrial lifting door PLC program need to have?

1. Correctness

The PLC program must have very good correctness, which is the most fundamental requirement for the PLC program. If this cannot be achieved, the others are useless no matter how good they are.

2. Reliability

Procedures must not only be correct, but also reliable. Reliability reflects the stability of the PLC program, which is also the basic requirement for the PLC program.

Sometimes there will be some abnormal working conditions when the industrial lifting door is running, such as temporary power failure, sudden call and so on. A good PLC program can recognize this, and can be connected with normal conditions, so that the program can be adapted to a variety of situations, and the scope of application of the PLC program can be greatly improved.

3. Shortness

A good PLC program should be as short as possible. A short program can save program execution time, improve the response speed to input and the readability of the program.

4. Time-saving

Short programs can save program running time, but short and time-saving are not exactly the same thing. Because the running time of the program is not only related to the number of instructions of the program, but also related to the instructions used, the execution time of different instructions is different. The calculation of the time to run the program is more complicated. If the time required for the program to run different instructions can be reduced, the response speed of the PLC program can be greatly improved.

5. Readability

The readability of the PLC program is better, that is, the program should be clear and not confusing. This not only makes it easier for programmers to debug their programs, but also makes it easier for others to understand the programs and for users to maintain them.

6. Easy to modify

Ease of modification means that it is easy to modify. If a program that is easy to be modified does not need to be reprogrammed in some special cases, it only needs to be slightly modified on the original program, which can greatly improve its utilization rate.
