Beschreibung
Zusammenfassung:	A tamper detection apparatus includes a switch and a tamper detection circuit with a non-volatile memory in an industrial product enclosure. In response to the switch detecting a door or panel of an industrial product enclosure being open when an electronic component or system in the enclosure is unpowered, the tamper detection circuit stores a tamper event code in the non-volatile memory. After the electronic component or system is powered, a system processor obtains the tamper event code from the tamper detection circuit and refrains from operating a machine or process pending reset of the industrial product by a user.
