CDS maintenance summary Tuesday 1st December 2015

FMCS EPICS channels added

WP5631. John, Bubba, Patrick, Dave

The FMCS to EPICS system was modified to add the corner station control average temperature channel. Both the raw channel (in degF) and the degC channels were added to the IOC. The new channel names are:

H0:FMC-LVEA_CONTROL_AVTEMP_DEGF

H0:FMC-LVEA_CONTROL_AVTEMP_DEGC

These channels were added to the DAQ for trending by modifying H0EDCU_FMCS.ini

Beckhoff Vacuum Gauge channels added to EX and EY.

Patrick, Dave:

Please see Patrick's alog for full details. After the Beckhoff changes were made, the ini files were generated and copied into the DAQ chans area.

DAQ restart

Jim, Dave:

To apply the Beckhoff and FMCS changes the daq was restarted at 12:32PST. This was a very messy start and took about 25 minutes to get the DAQ back. The main issue was the monit system on h1dc0 was trying too rapidy to start the data concentrator, resulting in duplicate ini and par files in the running configuration directory. In the end we started the data concentrator manually to get the system running. We will investigate the monit settings offline.

DIAG_MAIN guardian has code change, found error and fixed it

Jeff, Dave

After the long h1nds0 downtime, Jeff was getting the guardian nodes which use NDS back by reloading them. The DIAG_MAIN node would not run, giving an error saying float and int datatypes cannot be bitwise-anded. I found the error in DIAG_MAIN.py and fixed it by casting the ezca to an INT before bitwise AND. We tested the new code by stopping and restarting the CW hw-inj. The operator saw the message on Guardian MEDM and the verbal system announced the error every second.

h1lsc stuck testpoint cleared

Dave:

we had a stuck testpoint on h1lsc for some while, I cleared them.

Test change of filter module on h1pemmx

Dave:

To test the robot updates of filter files to daqsvn, I made a blank-line change to H1PEMMX.txt and loaded it on the front end.

due to the extended DAQ downtime, there are no H1 DAQ frames between the GPS times:

1133036992 (Dec 01 2015 20:29:35 UTC)

1133038720 (Dec 01 2015 20:58:23 UTC)

These times are those of the last frame file before the outage and the first file after recovery.

In the course of the FMCS change it came to light that the svn checkout that the IOC target directory updates from is not up to date.
svn checkout: /ligo/apps/linux-x86_64/epics-3.14.12.2_long_h0/iocs/fmcs
target directory: /ligo/lho/h0/target/h0fmcs

I made the change to the db file in the svn checkout, ran make, and updated the target directory from it. I then stopped the IOC and restarted it from the updated target. However, when I later tried to check in the modified db file, it would not accept it, because the svn checkout was not up to date, and the directory structure has changed in svn. So I copied the db file out of the way and ran svn update. I then realized that the svn checkout of the device support directory is also not up to date. At this point I am holding off on making further changes.

So as it stands:
The FMCS IOC target directory has been updated and the code is running out of it, but the directory it updates from is no longer compatible with it and the change to the db file is not in svn. I think I need to pause and consider how best to proceed.

I have modified the FMCS Cornerstation oveview MEDM screen to show the new Control Average temperature (both degF and degC). The new chans are located in the top right corner of the screen.
