The following slow channels have been added and are now being recorded by FB.
C1:ALS-X_OVEN_TEMP
C1:ALS-Y_OVEN_TEMP
C1:ALS-BEATX_FREQ
C1:ALS-BEATY_FREQ
Details:
In order to integrate the data collected by the Raspberry-Pi from the Y-end doubling oven temperature controller and also the data from the frequency counter which will be hooked up to monitor the beat frequency, Koji helped me set up some slow EPICS record channels (in ALS as we felt this was most appropriate). The procedure for setting up slow channels was as follows (virtually identical to what is detailed in this elog:
- Add the channel names to the file C0EDCU.ini (path = /opt/rtcds/caltech/c1/chans/daq/C0EDCU.ini).
- Make a database (.db) file so that these channels are actually recorded (path = /cvs/cds/caltech/target/c1aux/als.db).
- Restart framebuilder.
- Verify that the channels indeed exist and can be read and written to using ezcaread and ezcawrite.
I will now integrate these channels into my scripts, and make some simple MEDM screens.
