More precise timing for record processing

["Sobhani, Alex via Tech-talk" <tech-talk at aps.anl.gov>]

The SCAN field lets you choose from .1, .2, .5, 1, 2, 5, or 10 seconds. In cases where this is not enough, is there a simple way to make a record process at other intervals such as 2.7 seconds or 5.4 seconds, specified at runtime? I know you can add options for more periods of the SCAN field by editing dbd files, but you cannot change your mind at runtime.

 

I envision something like this:

 

record(timer, “BL0:mytimer”){

                field(PERI, 2.7)

                field(FLNK, “BL0:mytrigger”)

}

 

And then subfields to enable/disable it.  

 

Does anything like this exist? I would imagine that something like this would be very generally useful.
