    Default Elements Invisible Sometimes

    Hello,

    In Zenon7.20 elements are getting invisible sometimes please refer screenshot. It is properly running from last 4 months suddenly issue occurs and now it seems that it is solved but we are not able to found the root cause for the same.

    Operating system windows 8.1. Windows updates are stopped.
    Can you please suggest causes behind this issue.

    Regards,
    Rahul.

    Default Re: Elements Invisible Sometimes

    Possible explanation could be that zenon Runtime is not displaying screen elements linked with not existing functions, variables or symbols; or variables never received from a driver.
    On your screenshot: what kind of screen elements are you using? what is linked with?

    Hello,

    It is working properly now with same RT so how can we say that variables never receive from driver or not existence of variable?

    In above screenshot I have used "Combined Element" as element and attached variables with Boolean datatype.
    also for Numeric elements we have faced same issue as attached.

    PLC: Siemens 1200 and driver used is "S7 TCP-IP driver".

    Regards,
    Rahul.
