    Currently have an Allen Bradley 1734-AENT (CIP Ethernet) Module, with 4 points of IO. In the first slot is two 1734-IB4 (4 point Input), and in the second slot is two 1734-OB8 (8 Point Output). The point IO is configured . I have downloaded Codesys to run on my Raspberry Pi 3 b+. The code runs on my PI, I have just a simple program the input aren't update

    the outputs haven't problem since I can force each of them without problem.

    Anybody else bumped into this problem yet and able to help?

    I'm using the newest releases of Codesyscontrol and Codesys Development system.

    the inputs are not updated, because you don't use it in any program. To update without any usage, you have to change the update mode in the EtherNet/IP I/O Mapping section to: Enabled 2 (always in bus cycle task)

    thanks D. Kugler for your answer.
    I have modified the file, changing the update mode in the EtherNet / IP I / O Mapping section to: Enabled 2 (always in bus cycle task).
    the entries, at first take a correct value, but then they are not updated.
    I add the new file.
    Any more idea than it could be?
