    Good morning @Devious,

    A good place to start is the selection guides:

    Flex I/O: https://literature.rockwellautomatio...g002_-en-p.pdf

    Point I/O: https://literature.rockwellautomatio...g001_-en-p.pdf

    Today, the biggest difference is the number of I/O points per module, and number of modules per Ethernet Adapter.

    Flex I/O (and the newer Flex 5000) has a design where the I/O module sits on a base that resembles standard terminal blocks.

    Flex I/O also has a maximum of 8 modules per adapter.

    Point I/O is much thinner than Flex I/O, and Point modules typically have less I/O and I/O terminals per module.

    That said, Point I/O adapters support up to 63 modules, but like the newer 5069 Compact I/O require "Power Modules" every so many modules as the Point I/O backplane can't carry enough current to power all 63 modules.

    A good way to compare 1794, 5094, 1734, and 5069 I/O is to use the distributed I/O wizard in IAB:

    Hope this helps!
