This page describes how to edit the vacuum controls MEDM screen.
1) Go to /cvs/cds/caltech/medm/, or type "cd /cvs/cds/caltech/medm".
2) Choose c0 or c1 (depending on the sub-system you're interested in). In this case we want to "cd /c0/ve" This directory contains .adl files, which are the files loaded by the medm software
3) To edit an .adl file, just type medm filename.adl. An example is "medm C0VAC_MONITOR.adl".
4) To edit displayed text, simply click on the text, then scroll down on the pop up screen, and change the text box. Remember to hit enter afterwards.
5) To save it, go to the small popup labeled "medm" and go to File and select save. Alternatively, just hit ctrl-s.
6) To change the actual channel being displayed, select the box, and enter a new readback channel. Don't forget to hit enter.
To edit the EPICS database file (if for example you're changing a channel name from C1:Vac-TP1_lev to C1:Vac-TP1_ala), you need to edit the .db file.
1) Go to /cvs/cds/caltech/target/
2) Go to the subdirectory you want (in this example, /c1vac1
3) To edit the .db file, just type emacs filename.db. An example is "emacs Vac.db".
4) Find the channel you want to edit. ctrl-s then typing C1:Vac-TP1_lev, would take you to the next instance of that channel in the file.
5) Change the channel name. Make sure you change all references to it approriately.
6) Save the file. ctrl-x ctrl-s will save.
You will now have to restart the front end (like c1vac1) running the newly modified code, as well as the frame builder. Instructions can be found on the computer restart page.
