Because the indicators are on the POINTBus, it means a problem with the module itself or the POINTBus configuration.

Is the module newly installed, or has it been running for a while ?    If it failed after running for some time, and simple re-seating it or cycling power does not recover it, then the module must be replaced.

If it is newly installed, maybe the problem is in its slot number configuration.

Re-seating means physically removing a circuit board, I/O module, controller card, etc, and reinstalling it. It's a bit of a placebo but surprisingly, solves a lot of problems.

Cycling the power means turning the power completely off, waiting the minimum amount of safe time, then turning power back on. If there is no safe time specified in the manual, one minute with power off is usually sufficient.
