Subject Re: [S7-Scraper| scraper functionality extension

Hi Tim,

I think that's a great addition. To me it looks as if "Timer" and "Value Change" are just
different trigger mechanisms.
If this is implemented in a non-hacky way (which I would not expect) I think supporting different
trigger strategies sounds great and it would be a good addition to the PLC4X project.
Could even imagine having some sort of externally triggerable mechanism.

    Hi everybody,
    we currently have an application where a block of data from an S7 device shall only be
acquired when a specific variable has been set to a specific value.
    So for this application we need something like a triggered scraping job rather then the
existing scheduled scraping job.
    Right now i’m developping a solution for that, based on the existing scraper, in a forked
repo ... will this be something thats interesting as well for productive repo?
    What do you think or any ideas for further scraper functionality?
