    Which driver are you using? And which zenon version, service pack and build?


    Normally when the variable is switched to alternate value, and something is changed and the runtime is reloaded, the variable should keep the alternate value active!

    Try to activate the driver option "Variable image remanent"

    The option "variable image remanent" indeed saves the variable status and alternate value, also when closing and starting the runtime.

    However after a normal reload of the runtime, the alternate value should still be active even when this setting is not set.

    How do you activate the alternate value? And how do you deactivate it? Is there something in your project that may switch the variable to spontaneous value after a reload? (e.g. in your VBA - project active for example)

    When you try with a new small project, with only one variable in a numerrical value element in the screen, and activate the alternate value through the set value dialog, is this also reset when you reload?
