Integer Addressing at the Bit Level

    Hi all,

    I am using CODESYS for the very first time. The problem I am facing is that I have an integer in the PLC code and I am using each of the bits to control a coil.

    In the visualization I created 13 buttons to control Int.0 to Int.12 but for some reason all the bits in the second byte of the Int are not responsive. to overcome the issue I had to write a value to the integer instead of changing individual bit status.

    Does any body know why this is happening, why can't I toggle Int.8 to Int.15 from the HMI.

    Thank you.
