It is very reliable to control the system with PLC. This is because PLC has taken many measures in both hardware and software to ensure that it can work reliably. In fact, if PLC does not work reliably, it cannot be used in industrial environment, and it is not PLC.

In terms of hardware:

The input and output circuits of PLC are electrically isolated from the internal CPU. Its information is transmitted by optocoupler or electromagnetic device. In addition, the CPU board also has shielding measures against electromagnetic interference. Therefore, it can ensure that the PLC program can operate normally without external electrical and magnetic interference.

The components used by PLC are mostly contactless, highly integrated, and not too many, which also provides a material basis for its reliable work.

In terms of mechanical structure design and manufacturing process, in order to make PLC work safely and reliably, many measures have also been taken to ensure PLC vibration and impact resistance. The ambient temperature can be as high as 50 ℃, and some PLCs can be as high as 80-90 ℃.

Some PLC modules can be hot standby, one host works, and the other host also works, but it does not participate in control, only for backup. Once the working host fails, the hot standby can automatically take over its work.

There is further redundancy. The one-out-of-three design is adopted. CPU, I/O module and power module are redundant or some of them are redundant. The three sets work at the same time, and the final output depends on the results of most of the three decisions. This can make the probability of system failure almost zero, so as to be foolproof. Of course, the cost of such a system is very high, and it is only used in particularly important occasions, such as the crossing control system of railway stations.
