Troubleshooting - brownout?
Hi all,
I'm very green when it comes to arduino applications and processes.
I have an application at work that takes input from a PLC via an on and off signal.
When both the temperature high and temperature low signal are off, our arduino seems to detect the oven is at the correct temperature. When the low signal is given, the oven is under temperature etc. The oven low comes via digital pins and over temp via analogue.
The design is that of my predecessor who breathed these things and left no notes.
I have this working perfectly on 5 other stations but one station is giving me a head ache.
Our Yun Rev2s are powered via a poe splitter and the troubled one is also. Now sporadically it seems to just hang, cannot ssh or ping. I cannot for the life of me figure why, I've changed the shield. Arduino, splitter and had an electrican double check the voltages on the wires in the pins. Could it be a brown out issue from the splitter as poe not delivering consistent current?
I have watchdog on it for any issues with the microcontroller. I'd appreciate any insight as I am tunnel visioned at this point..thank you for listening to my rant
tldr yun rev2, losing connection but still on. Sketch works perfectly with 99.999 uptime elsewhere in facility. Think power issue
