    Hello everyone,

    I need to develop a UPS for a Raspberry Pi 4 with CODESYS implementation. This UPS should guarantee that the PLC is able to shutdown and push the retain-variables to a connected NVRAM. But because of missing space it needs to be configured as small as possible.

    Does anyone have some typical times for the Runtime to completely shutdown?

    Thanks for your answers.

    Not easy to answer, depend on the application and on their taskconfiguration -
    if there are tasks which have large cycletimes (like 10s) which I would not recommend your shutdown
    could be pretty slow.
