- Non-volatile memory life has expired due to excessive write/erase cycles or natural degradation.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the exact error code 000E0000 and its description 'Non-volatile Memory Life Exceeded' in the NX-series CPU Unit's diagnostic buffer or Sysmac Studio.
- 2
Inspect all status indicators (LEDs) on the NX-series CPU Unit for any additional warnings or abnormal states that may accompany the memory life exceeded error.
- 3
Measure the incoming supply voltage at the CPU Unit's power input terminals and confirm it is within the specified operating range (e.g., 24 VDC ± 10%) according to the Omron documentation.
- 4
Access the CPU Unit's system log and event history via Sysmac Studio to identify any prior or related memory errors, power anomalies, or unusual events that might have accelerated memory degradation.
- 5
Backup the current PLC program, parameters, and configuration data from the NX-series CPU Unit using Sysmac Studio to safeguard against data loss before further troubleshooting or unit replacement.
