Subject: Connecting CTC100 to EPICS/rtcds system 

I added an EPICS channel for the heater power controlled by the Megastat CTC100.

1. Added a function to the protocol file to query the heater power: /opt/rtcds/caltech/c4/target/qil-nfs/CTC100/iocBoot/iocCTC100/protocols/ctc100.proto

2. Created a new channel C4:CTC-MS_HEATER_POWER_VAL in the database file: /opt/rtcds/caltech/c4/target/qil-nfs/CTC100/db/ctc100.db

3. Restarted st.cmd:

cd opt/rtcds/caltech/c4/target/qil-nfs/CTC100/iocBoot/iocCTC100/
./IOC_start_cmd.sh

At this point I confirmed I could access the channel via

caget C4:CTC-MS_HEATER_POWER_VAL

4. Restarted daqd@standiop.service

ssh fb4
sudo systemctl restart daqd@standiop.service
