Vacuum System Migration

Migration from RaspberryPi to MOXA/Saba-taro

Procedures

1. Stop Raspberry Pi DAQ (comment out CC10.py) on crontab@k1script1

   controls@k1script1:~$ crontab -e
   # * * * * * /users/DAQ/EpicsDAQ/bin/CC10.py      --daq --wait 15 > /tmp/crontest-cc10.log 2>&1
   # * * * * * /users/DAQ/EpicsDAQ/bin/CC10.py      --daq --wait 45 >> /tmp/crontest-cc10.log 2>&1

2. Shutdown Raspberry Pi

   pi@raspberrypi:~$ sudo /sbin/shutdown -h now

3. Parallel work
   • Hardware works
     1. Disconnect Raspberry Pi from CC-10
     2. Connect MOXA/Saba-taro to CC-10 and set up MOXA/Saba-taro
   • Software works
     1. Remove channels from the list of Raspberry Pi DAQ channels

        controls@k1script1:~$ emacs /users/DAQ/EpicsDAQ/etc/CC10/VAC.json

     2. Resume Raspberry Pi DAQ (uncomment CC10.py) on crontab@k1script1

        controls@k1script1:~$ crontab -e
        * * * * * /users/DAQ/EpicsDAQ/bin/CC10.py      --daq --wait 15 > /tmp/crontest-cc10.log 2>&1
        * * * * * /users/DAQ/EpicsDAQ/bin/CC10.py      --daq --wait 45 >> /tmp/crontest-cc10.log 2>&1

     3. Add channels to the list of MOXA channels.

        controls@k1script1:~$ emacs /users/DAQ/EpicsDAQ/etc/CC10/MOXA_VAC.json.txt

     4. Update IOC data base

        controls@k1script1:~$ /users/DAQ/EpicsDAQ/share/scripts/generate_daq_conf.py -s cc10 -o db > /opt/rtcds/kamioka/k1/target/k1vac/db/example_vac_gauge.db

     5. Restart vacuum IOC on supervisor@k1script1

        controls@k1script1:~$ sudo supervisorctl restart vac_ioc

4. Update daqd configuration file

   controls@k1script1:~$ /users/DAQ/EpicsDAQ/share/scripts/generate_daq_conf.py -s cc10 -o ini > /opt/rtcds/kamioka/k1/chans/daq/K1EDCU_VAC_GAUGE.ini

5. Restart daqd from DAQ guardian

Add new channels with the MOXA/Saba-taro system

3. Restart daqd from DAQ guardian
4. Update trend-monitor configuration file

   controls@k1script1:~$ /users/DAQ/EpicsDAQ/share/scripts/generate_daq_conf.py -s cc10 -o conf > /users/tyamamoto/longTermTrendMonitor/conf/vac.lst
