Number of Sensors Verify Error

Omron · NJ/NX-series Machine Automation Controller

What does 24780000 mean?

The system detected a mismatch between the configured number of sensors and the actual number of sensors physically connected. This discrepancy prevents correct system operation based on expected sensor inputs.

Common Causes

  • Configuration setting for sensor count does not match the physically connected sensors

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Verify the configured number and type of sensors within the Omron NJ/NX-series controller's Sysmac Studio project against the actual physical installation and system design documentation.

  2. 2

    Inspect all sensor wiring and connections for integrity, damage, and proper termination at the Omron I/O modules and the sensors themselves.

  3. 3

    Verify the operational status of each individual sensor by observing sensor indicator LEDs and confirming corresponding input states in the controller's I/O monitor.

  4. 4

    Measure the supply voltage at the terminals of each physically connected sensor to confirm adequate power delivery.

  5. 5

    Check the diagnostic indicators (LEDs) on the relevant Omron I/NX-series I/O modules for any errors that could affect sensor input detection.
