WP13303 Reimage PWRCS Beckhoff, update Corner HEPI Pump controller INI
Patrick, Erik, Jonathan, Dave:
Patrick created a new H0EPICS_PWRCS INI file. All of the EPICS channel names have changed since the first version of this system, and 40 of the new channels have old-channel equivalents. To preserve recent minute trends, the data acquired so far were transferred to the new names as part of the upgrade.
The sequence followed was:
- Remove the old names from the edc_green_ioc IOC. 43 disconnects at this point (40 from H0EPICS_PWRCS and 3 from H1EPICS_HEPIPUMPL0)
- Create the copy scripts to be ran on TW0,TW1 to copy the old files to the new, so that the new channels will "continue from where we left off"
- Create the new H1EDC.ini and verify its changes.
- Stop daqd on TW0 and TW1
- Run the copy scripts on TW0 and TW1
- Restart the 0-leg, followed quickly by restart of the EDC.
- Wait till 0-leg was fully operational, including TW0
- Restart the 1-leg
All went well except for the usual GDS1 needed a second restart, FW1 restarted itself after 5 minutes.
Here is a random new channel which has non-zero data trended back one month to view its data back when it had its original name.
