PG 522 Field Point I/O Activity Lights always on even when no output is requeste

I am making Time Duration outputs to a PG-522 Module. SOmetimes, even when I have no output the activity light stays on all the time. The only way to clear it is to reset the Field Point Communications. What could Cause this to happen?

Hi Pat,

 

The activity light does not tell you if your channel is in the ON or OFF state.  It tells you if the channel is generating pulses.  According to the manual, if you  are using the 1s resolution the max ON/OFF time is 65,535s.  This could cause the activity light to stay on while it looks like you have no output.
