<p style="margin-top:0;margin-bottom:0">After our last email, I started looking into WEDM and tested out converting one of our CSS test screen showing HMS magnet currents to EDM. I used one of accelerator's servers to check the EDM part.</p>

Do you guys have accounts on the accelerator network?<br>
<br>
The directory /cs/opshome/edm/hlc/spectrometers/ is setup with world <br>
write access so edm files can be put there. That directory contains a <br>
test file vacuum.edl which can be seen on epics web with:<br>
