Experimental Physics and
Industrial Control System

Hi
Hope someone has a good advice for me:

I implemented an XY-scanning table control using EPICS to handle an XY
step-motor table.
I use sscan records to implement automatic scans in x and xy-direction.
So far this works fine.

Now i want to add one more thing: Before the scan starts, i have to
start the DAQ system with a certain BASH shell-script, after the scan i
have to stop the DAQ with another shell script.

Can i somehow issue these shell-commands automatically before and after
the scan ?
Is there some record type available which can do this ???

I have been quite some time now, but could not find anything.

Any advice ?

best regards,
Christian
