Priya:
We often do this kind of thing using a scripting language such as Perl.
The EDM button is a 'Shell Command' widget, and it launches the Perl
script to perform the sequencing. The Perl script uses the EPICS Channel
Access module to read and write the accordant EPICS PVs for performing
the sequencing. Naturally, the script runs on the host that is running EDM.
While it seems desirable to implement everything using EPICS record
logic that runs on the IOC, it is invariably too complex to implement
that way. Other labs often use the SNL facility for such purposes, and
that is potentially a better method. Hopefully others will contribute
ideas about how to implement that.

Hi Priya,
I would do this with a sscan record. See

*Subject:* related to controls in edm
Hello sir,
I am beginner in EDM and I want to add a button in EDM. When I will
press the button then my progam should be start otherwise should not be
start. In case of my program, I am going from 10 mA(i.e. initial value
in current source) to 120 mA(i.e. final value) with step of 10.How to
use message button which act as a START button of my program and this
should be press(toggle) only one time and program should be proceed and
also I want to add stop button so that when press stop then whole
program should be stop.How to perform this task ,I have no idea because
for loop or while loop does not work in VDCT directly. Please provide
example for this type of task.
Thanks in advance......
