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.
