Does anybody have experience with UPS or supercapacity to run the revpi?
We have a revpi that is connected through ethercat with some IOs and it is running codesys: we do not need to keep the IOs up during the shutdown, so no power consumtion from there. What we need is a proper shutdown as we have some persistent variables in codesys, which are automatically saved when the codesys process is properly terminated.
What is the power consumption of the revpi itself? The only USB peripheral we have is a usb dongle for the codesys license, so it should not drain a lot of power from the USB.
We found some super capacitor which do not require any maintenance but their output at 1A is only for 5s, which I'm not sure it's enough for a proper shutdown, is that true? What are your experiences on that?
