SCB-68 digital input issue

Hi,

 

I have a fairly-new SCB-68 that is receiving 3.3V inputs from the raspberry pi. I currently use digital inputs P0.0 - P0.7 (pins 52... etc). However, I noticed today that some of the pins do not work - as in, they are unable to detect any inputs. Namely, I have an issue with P0.3 (47), P0.5 (51), and P0.7 (48). 

 

I definitely know that there are inputs going into these pins (because if I swap the inputs bewteen P0.3 and P0.4 I can detect the input on P0.4). Any ideas? Wondering if the fuse was somehow blown? How would you test for this?

 

Thanks!

SCB-68 is a terminal block. 

There is another module with the model name of NI-6xxx/7xxx which does the actual reading. If swapping the pin works, most likely some pins are malfunctioning. You might want to send the module for repair.

Yes sorry, my apologies. We do also have a PXIe-6341 that is coupled with the SCB-68. We have an extra control block (CB-68LP) so I'll try that and see if that makes a difference.

Thanks!
