If the error happens , you have an EMI issue.
The first and most effective fix is to power down the system, remove the card, clean the contacts with isopropyl alcohol, and firmly re-insert it. rnr motion card not found
Like all electronics, these cards have a finite lifespan. Capacitors leak, and integrated circuits can fail due to electrostatic discharge (ESD) or overheating, rendering the card a "brick" that no longer communicates. Troubleshooting Steps If the error happens , you have an EMI issue

Industrial environments are prone to vibration and thermal expansion. Over time, a card can physically "creep" out of its slot. A microscopic gap between the gold pins of the card and the backplane connector is enough to break the data circuit.
