Abstract
Methods and apparatus to monitor a power supply are disclosed. An example apparatus includes a first power supply included in a programmable logic controller (PLC), the first power supply to receive input power from a second power supply external to the PLC, and analytics circuitry included in the first power supply, the analytics circuitry to determine, based on the input power, a diagnostic parameter associated with the second power supply.
