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?
    
    Best
    Tim
