Hi,

LED CR16 is lit red.

From the 7I77 Manual
"The red LED CR16 indicates a watchdog fault, which is
expected before host communications are established"

What are the steps in determining the state of the fault?
Note: at this stage I dont have the 7I70, and 7I71 cards connected.

Also, the 7I77 pins dont show in the Halcmd results from suggested commands.

I'll work my way through this thread.

and see what I can progress.
