Thread: CR0451 not holding program

    Exclamation CR0451 not holding program

    I've got a CR0451 that I've been working on over the last 6 weeks or so. Everything has been fine until today it no longer holds the program after a power cycle.

    Any ideas as to whats gone wrong or how to fix it?

    Thanks

    That's strange. What happens when you power up the display?

    The screen was going blank and Codesys would state that there was no program in the HMI.

    In the end I loaded the program in to the HMI and pulled out everything using the Maintenance Tool, then reloaded it through the Maintenance tool and since then its been fine, even using codesys since. Not sure what that was all about!
