I hope you don't mind if I piggyback on your question.

Our 9472 seems to be working OK some of the time, but occasionally all of the LED's on top will cut off, and then a second or so later will come back on.

When the lights are on, we can control them with our code and the module works to control our pneumatic solenoids, but when the lights are out nothing happens.

Sorry I can't help with the original question, but maybe someone can chime in with something we can do to test the 9472 to see if it is operating properly.
