In order to make PLC work reliably, PLC manufacturers have taken many measures in both hardware and software aspects. For some PLCs with special reliability requirements, there are also corresponding special measures, such as hot standby, redundancy, etc. This has been described when introducing the characteristics of PLC. The purpose of reliability measures is to increase the mean time between failures (MTBF) of PLC and reduce the mean time to repair (MTTR) of PLC, so as to improve the availability of PLC.

A=MTBF/(MTBF+MTTR)

Where, A – effective efficiency

MTBF — Mean Time Between Failures

MTTR — mean time to repair

Of course, the larger the A value, the better. It can make full use of the PLC system. It is an important indicator of why PLC should be used. From the above formula, the larger the MTBF, the smaller the MTTR, and the larger the A. Therefore, the reliable measures of PLC are all around the improvement of MTBF and MTTR values.

Since reliable operation is an important feature of PLC and is crucial, how to improve MTBF and reduce MTTR, and the MTBF and MTTR values of PLC have also become important indicators of PLC performance.
