Dear collogues,

we have added a hotfix to the framework, to make sure, that no motor can be moved if the feedback signals are missing. This update will be done due to the mentioned issue in the readiness meeting this morning.

We will update the loops again after the weekend, with a proper solution.

The hotfix will send all devices of a loop into error if the feedback of a terminal in the loop is missing.

I will write a new entire in the Logbook, if we are done with the updates.

Cheers,

    Tobias

I have deployed the Karabo master (the HEAD of our development) in the control network for the Vacuum loop device server.

During last weeks Karabo was not able to cope with the data coming from the PLC for this loop (our biggest to date)
and would become unresponsive after 5 to 10 minutes.

The current system is online since 3.5 hours and is still responsive.

Please note:
This is a partial release and the GUI might show unwanted behaviour.
Please leave the vacuum loop untouched during the weekend.

In attachment you can find an example of unwanted behaviour and the DPS gui

Thank you very much and have a nice weekend!

Alessandro

Dear all, EPS loop is again up and running.

Thank you!

Dear all, I will update EPS loop in order to integrate new hardware changes. I will post a new entry when the work is done.

Thank you!

I have made an update for the Motion loop requested to test correctly the Attenuators. Now the loop is running again.

Thank you and sorry for inconvenience.

 Thanks, Alessandro,

Hello Andreas,
please use redmine for bug reports. I opened a redmine issue for this:

https://in.xfel.eu/redmine/issues/16265

Please log in and give more details on what you experienced.

In case of emergency contact your main contact person Wajid.

Cheers

Alessandro

Has anyone an idea why the motion loop is not working? Thanks Andreas

 Tunnel Open.

Mirrors:

Status:

• Vacuum will be closed on M1
• M2 installation tomorrow or latest on Monday

Vacuum Loop:

Status:

• Loop is up
• XGM was integrated but tests needed on the interlocks. Hence valves to DPS now in manual mode (overrides interlock)
• Interface to MPS has been successfully tested
• Need to test fast valve connection to VAC and to MPS (Status re cabling was unclear this morning)
• A few pumps still  have communication problems (to be discussed between AE and CAS)

EPS Loop:

Status:

• AE did most of the missing wiring
• Description of EPS interlock still missing. It is planned to start with just one imager in for first beam commissioning
• One fiber connection from Balcony room to DESY still to be done by DESY

Motion Loop:

Status:

• Problem on ELMO motors with linear drive persists. Needs additional testing

Imagers

Status:

• Both motors working on FEL imager
• Work should now concentrate on SR imager

Karabo:

Status:

• Problem in TCP implementation identified that is suspected to cause the long delays observed e. g. with the imagers. Now needs extensive testing
• Still no data recording achieved
• Stability still needs monitoring

Tasks for today:

• Work on GUI for the vacuum loop (J. Eidam, V. Bondar)
• Test XGM interlocks (N. Jardon, M. Planas, T. Matsopoulos)
• Continue tests with PBLM in the tunnels (M. Jidda)
• Test motion system of the imagers in the tunnels (A. Koch and W. Ehsan)
• Monitor stability and responsiveness of GUI Server and Log Servers (A. Silenzi)
• Set up monitoring of temperatures and pressures overnight (A. Silenzi)
• Push DESY to install fiber connection from Balcony rooms to MPS (P. Gessler)

Tasks for tomorrow:

• Put XGM into the vacuum interlock
• Perform careful testing of all interlock conditions for the vacuum

Other topics

• Regular SASE1 readiness meeting at 09:00 tomorrow in XHQ E1.173
• Need to perform tests with EPS interlock conditions
• Need to test fast valve connection to VAC and to MPS
• Gas system for diagnostics needs to be flushed

XTD2, FEL imager with Wajid

Screen, motor, switches - ok, minor braking switch issue.

LED, camera power – ok.

Filter, motor, parameter issue, should be solved now, to be tested again today.

EPS tests and SR imager tests, to be done.

XTD9 cameras, no power, will check today with Bernard.

I expect that some of us may need the weekend as a reserve (e. g. mirror installation). So we should probably say no. Let's discuss more tomorrow at 09:30 

test finshed.

both stages were moved.

voltage value and position read out from encoder opposite in directionality

some strange limitation on the postiion range seen.

both stages are now at around the 0 position with few mm error.

XD to ask alio/nanoomotion on the matter

XD will provide few lines of comment

Dear all,

The XGM XTD2 is already into the Vacuum loop and the loop is running. We would continue with the interlock tests today in the afternoon, but would not affect to other parts of the Vacuum loop.

Also was requested to change the Karaboo names of the devices in XGM XTD2, therefore a firmware updated would be necessary and would be performed today in the afternoon after VAC-MPS communication tests.

Thank you!

The rack 1.18 in XTD9 is not operational at the moment because Nicola is working on it. Nerea, Tobias or others let me know when it is fully operational again. This avoids checking it in the tunnel. Alternatively, let me know if I can check remotely.

Tunnel Open.

Vacuum Loop:

Status:

• Communication problem with Ion pump controllers is fixed after adjusting controller settings
• Loop is now down to allow inclusion of XGM

EPS Loop:

Status:

• Temperature sensors return reasonable values after EPS loop fix
• EPS to MPS interface is working but fiber to central desy interface still lacking

Motion Loop:

Status:

• Should be up for testing PBLMs and Imagers

Imagers

Status:

• Test of FEL imager ok, but hampered by occasional slow response of the system
• SR Imager needs work on the driver

Tasks for today:

• Include XGM in Vacuum loop (N. Jardon, M. Planas, T. Matsopoulos, V. Bondar)
• Test updated MC2 lib with PBLM in the tunnels (N. Gerasimova, M. Jidda)
• Work on camera driver for SR imager (A. Koch and W. Ehsan)
• Test motion system of the imagers in the tunnels (A. Koch and W. Ehsan)
• Monitor stability and responsiveness of GUI Server and Log Servers
• Set up monitoring of temperatures and pressures overnight
• Push DESY to get fiber connection to MPS (P. Gessler)

Tasks for tomorrow:

• Terminals need to be added and firmware adjustments made in motion loop (take loop down as early as possible for one hour)
• Test EPS inputs to MPS system with DESY people
• Power down crate 1.15 for grounding. Could take longer than one day

Other topics

• N. Jardon needs complete info of motor names in rack 1.18

Dear all,

Tomorrow at first hour, some hardware modules would added in Rack 1.1 and 1.9 in XTD2 in the Vacuum loop. Therefore the communication would be interrupted till the firmware is downloaded to the PLC, around 10h-10.30h should be running again to add the XGM XTD2 into the loop. Although, I will post a new entry to let you know.

Thank you,

Here are the updated values for the temperature sensors inn the EPS loop.

Now Thermocouples work!

J. Eidam, V. Bondor, T. Freyermuth checked Ion pump controller settings in XTD2 and XTD9.

Many controllers were found to have incorrect settings. All pumps in XTD2 now respond and give pressure readings. There remains the problem that the PLC is looking for the wrong channel in the case where 2 pumps are connected to one controller (Is 1 & 3 and PLC looks for 1 & 2). J. Eidam now checks channel numbers on all controller. T. Freyermuth then regenerates the firmware. A. Silenzi set up pressure recording for pumps P10050I, P10060I and P10200I to run overnight. 

since tunnel access is now possible 

Interlocks in the northern fan are broken!
