cRIO cutting out 5 s after collision

[Al Skierkiewicz]

When you see a 5 second gap after a hard collision, expect that the radio power supply was interupted. Not long enough for a complete reboot but certainly long enough for the radio to make a recovery mode and reestablish comms with cRio and field. Just enough will corrupt some of the data. With the 2Can in the loop, check to see how long it takes for the 2Can to recover from a power fault. That is more likely the issue. You moved the comms link so you likely moved the power as well. This is just an accident waiting to happen again. Check this when you can.
I recommend against hot glue for two reasons. If you have applied it correctly, you might not be able to change something if it has failed. That might forever damage the device. If it does pull apart easily, then the hot glue was not applied correctly in the first place and you are only fooling yourself that you fixed the issue. Just because you think you see adhesive applied in an industrial device, do not think it was meant to come apart. The manufacturer might just think the part is expendable.
