Number of Sensors Over Limit

What does 24790000 mean?

The total number of sensors connected to the system exceeds the maximum allowable limit. This overload can cause system instability or prevent proper initialization.

• Exceeded the maximum permitted number of connected sensors

Click steps to track your progress.

1. 1

   Verify the total count of physically connected sensors against the maximum input capacity specified in the Omron NJ/NX-series hardware manuals for the controller and its I/O expansion units.

2. 2

   Inspect the I/O map and configuration within the Omron Sysmac Studio project for the NJ/NX controller to ensure it accurately reflects the physical sensor count and does not exceed configured limits.

3. 3

   Check all sensor wiring for correct termination, absence of shorts between sensor signals, and any parallel connections that could cause multiple inputs to register from a single source or erroneous counting.

4. 4

   Review the specific I/O module datasheets to confirm the maximum number of inputs supported per module and ensure the current sensor load does not exceed these individual module specifications.
