Tom Cash, director at Foxmere, explains how engineers can ensure PLCs last for their expected duration
Programmable logic controllers, or PLCs, can survive for more than 20 years, and it’s something we see regularly here at Foxmere.
Although the component parts of a PLC, such as central processing units (CPUs) and power supply units (PSUs), boast long lifespans, components such as input/output (I/O) modules and communication modules are not so robust.
In fact, about 80 per cent of PLC failures result from field devices, I/O module failure or power supply issues.
