NI 9403 cRIO overcurrent status detection

[Tim_R]

When the 9403 detects an overcurrent condition all channels are tri-stated (inputs and outputs).  This overcurrent mode would prevent an application from reading the state of any input channels (as I understand). Is there a way for an application to detect/determine if the overcurrent mode is active? e.g. is there a status register indicating errors?

The 9403 does not have an output to show whether the over-current protection has been tripped. If you want to read that in an application you might have to program some logic to infer whether you're in that state. Maybe looking at a dummy line and checking for a change in state.
