  • Form OnActivate report message when using Write Object function

    Hello,
    in my project i have 2 forms; in each one I have a button that allows me to switch form. I am also connected to a Rasbperry host with which I can capture report messages coming from the display.
    I have noticed that if I switch form using touch buttons I get the correct event message sent to host, while if I try to switch from host using a WriteObjectValue message the new form is correctly displayed but no activate message is sent from display to host.
    Is this a normal behaviour or am I missing something?
    Thank you,

    Kind Regards
    Michele

    Dear Michele,

    Good Day.

    Yes that is a normal behavior. In using write object value, the display will just reply with ACK if the message is correct and NAK if the display did not understand the message.

    You can check ViSi-Genie Reference Manual for more information.

    I hope this helps.

    Best Regards,
    Ferdinand
