DataChanged events

RussDRussD United States

Are there any plans to expand the RapidDomain with DataTypeChanged events?

It would be very useful to be able to subscribe to variables as needed and/or get changed events by RAPID type.

Am I missing something, i.e. is  there a mechanism in place to do this?

  • Hi Russ,

    no, you are not missing something, it is not available, but has been added to the requirement specification (change event for persistent variables; as far as I know for datatypes string, bool and num).

    A workaround would be subscribing to signal change events (virtual signals should work, too).

    Hi Russ,

    in RAB 5.06 you can add event handlers for persistent Rapid data changed events.

    Hi Urban,

    Is there a 5.06 RAB beta build that can be downloaded yet?

    the release version should be ready next week or so. Since I'm outside ABB I cannot download any version, but the current FlexPendant SDK beta is very stable.
