Digital Out Pins briefly switch to HI when booting

Hi Nicolai

Please have a look at this video for the behavior I mentioned.
Both DOs and Relays are triggered briefly on Power ON.

Hi Nicolai,

Any suggestions on why we observe this behavior and/or if there is something we can do about that.

Thanks

I have exactly the same problem with the revpi compact.
Activating all outputs on power-on and boot is not acceptable for an industrial PLC.

@KUNBUS: What is your solution? Or do I have to send the devices back and choose a different, real industrial grade product from someone else?

Thanks and best regards,
Jürgen

Hi all, just seeing if there's has been any progress on resolving the issue with all DOs briefly turning on during a reboot??
