Hi guys,

I have two two 1732-ACNR point IOs that cannot be detected in the controlnet network. The problem started after a plant shutdown due to power interruption. When the PLC power was turned-on the point IOs cannot be detected.

RIO 1 LED: Controlnet A status is flashing green
RIO 2 LED: Module Status, Pointbus Status, and Controlnet A Status are all flashing green.

I tried replacing the IO adapters. The result is still the same.

I am not sure if this is a cable problem or program problem.

thanks
