Re: Limit Switch return value

<R67> All outputs from sensors, custom circuits and additional electronics shall connect to only the following:
A. Other custom circuits, or
B. PWM Out, I2C, Relay or Digital I/O ports on the Digital Sidecar, or
C. ANALOG IN ports on the Analog Breakout.
D. Ethernet Port 2 on the cRIO Mobile Device Controller (to which the Kit Of Parts-provided camera, and only that camera, may be connected).
-------------------------------------------------------------
I moved my limit switches back to the digital sidecar and am programming them instead. I didn't want to have to fight with inspectors on game day and have to rush some code to reinstitute my limit switches so I am doing it through the sidecar from the beginning. I looked on Q&A and didn't see a specific allowance for using the jaguar limit switch capability.
Does anyone know whether I am being too careful or could I use the much easier built in limit switches on the jaguars?

I have submitted a question to the Q/A about this. I agree that <R67> as written doesn't allow it, so I'm hoping it will be amended.
