The EPICS sscan record is designed for doing exactly this type of thing. I will collect data into arrays in the record, and in conjunction with the saveData utility in the sscan module will write the values to a portable binary disk file.

Subject: How can I collect data values
Hello,
I'm working on an automatic data analysis of electron beam (emittance
measurement with a wire scanner and a magnetic lens) with EPICS.
I get values from the hardware (self build measurement cards). The
device support put the values into a longin records (this part is fixed,
because it is already used for other applications).
I need to gather the values (will be a position and a corresponding
current) for a certain amount of time (approximately 1000 to 10000
values) and then hand it over to a subroutine, to perform the analysis
(like fitting a curve onto the data). It should all run on a debian machine.
My problem is to collect the data with EPICS. I thought about collecting
them somehow in a waveform record, but i have no idea, how to do this by
using other records instead of the device support.
Best regards,
Kai Stein
