Hello, I use a Industrino board 32u4, this board was mounted inside a elettronic cabit of one our machine, whit some relay and some inverters for 3 phase motors.
When I wrote the sketch and test on the table everything is ok but when I put the board on the machine, every 3 or 4 minutes Industrino crash. To restart the application a reset is necesary. I think this problem come from the 24v input for the V+ how I can filter this 24v?? The board it self does not have some filter on the V+?? This is realy strange for a industrial product. I'm waiting your feedback as soon as possible.
Hello, thanks for your suggestions, I already try to check what happens whit the serial connections and the resul is after 3 or 4 minutes Industrino crash no serial communications nothing, this happen also with a real simple sketch like a counter i++ and serial.print(i). In the next few hour I check with the oscilloscope what happen on the V+ pin. May be some one know a filter device for reduce the spike on V+?? Thanks a lot and best regards!!
Industruino is a very solid platform, I have them installed in all sorts of environments without a problem.
All I/O's are actually galvanically separate from power, so you should be able to obtain a quite stable operation.
In particularly noisy environments, you might want to take extra measures to get your unit to work.
Filtering is actually an issue that should be solved mainly by your power supply unit.
If signal cables run a long distance in proximity of power inverter cables, these should be shielded and connected to ground on one side only.
Another issue could be temperature, if you fit inverters in the same space.
These are just general suggestions, as I never had this problem before.
Maybe you could use your serial port and find out when the Industruino is reset, on which operation I mean.
