Signs of a Failing PLC
Key signs of a failing PLC include fault LEDs on CPUs, I/O modules, or communication cards, Ethernet connectivity issues, intermittent network dropouts, overheating, or visible hardware damage. Many faults are caused by external field devices, wiring, or communication systems rather than the PLC itself.

The Real Reason Electrical Connections Fail
The Real Reason Electrical Connections FailWhen an electrical system fails, the instinct is to look at components, the drive, the relay, the sensor. Components are tangible, testable, replaceable. But the data tells a different story. In the majority of electrical failures, the component itself is intact....

What Happens When PLCs Are Stored Incorrectly
What Happens When PLCs Are Stored IncorrectlyThe assumption is almost universal in industry: PLCs are rugged hardware. They're built to run in harsh plants, tolerate electrical noise, and survive decades in panel boards. That reputation for toughness, however, refers to PLCs in operation, correctly installed,...
