The reliability of products is originally reflected in the failure rate. The lower the failure rate is, the higher the reliability is. In order to reduce the failure rate, PLC manufacturers should first find the failure factors, which should be analyzed from the internal structure and external environment of PLC.
From the internal structure of PLC, it can be divided into software and hardware, and the software can be divided into bottom software, using software and programming software; Hardware is divided into CPU, power supply, I / O, communication, connector and mechanical structure.
Firstly, the failure rate of PLC hardware is analyzed. Because of the special program structure of PLC, in terms of CPU and I / O circuit, the failure rate is mainly related to the hardware structure planning, the selection of components, and the production process. The selection of hardware planning and meta equipment mainly depends on the level and experience of R & D. moreover, after the use of several generations of products, we can find the existing problems. For manufacturers with a certain history and scale of use, they can control this aspect better. In terms of production technology, manufacturers with their own production lines can analyze the characteristics of their own production lines through repeated production, especially the shortcomings of the production process. Therefore, generally, even if the first two batches of each product have problems, they can improve and improve the production line through fault diagnosis. Therefore, there will not be too many problems in this aspect.
