please find the new (extended) components list under the old link given in the minutes http://tinyurl.com/zn7otsa ,

and check whether all components are included and charakterized by the correct data.

The Vacuum Controls Commissioning Task Force initially helped to get the vacuum components extending from the gate valve at 2678 m to the gate valve at 2730 m in XTD2. This comprised the valves and pumps and the associated vacuum interlock logic. The necessary components were all installed and locally tested. As the next step the PLC firmware for the control of these devices was generated including the interlock logic. Finally the system was connected to version 1.47 of Karabo, which was able to monitor and control all components. A live demonstration is currently still outstanding.

As the next step the vacuum section considered should be extended upstream to include all components up to the gate valve at 2630m. In addition to vacuum components this should include the installed photon beam line components. The goal is to include all these systems into one continuous vacuum, commission all systems locally, generate the PLC firmware, implement the required vacuum interlocks, monitor the state of the system remotely via the PLC command line interface and eventually connect to Karabo and monitor and control the system via Karabo remotely using the consolidated version 2.0. While this commissioning effort is going on, development should occur on three days during the week (Mo-Wed) while the system should be operated continuously during the remaining time, thus also testing long-term stability. This should be achieved by the end of 2016.

I have included the status columns provided by Alessandro and Sandor in the component list. Please find it in the usual location here: http://tinyurl.com/zn7otsa

 Karabo to PLC communication has been tested successfully in the SA1 Vacuum installation.

 I reproduced the behaviour of the PLC on beckhoffSim. This reproduces the same behaviour seen in the tunnel devices (devices hang).

Implemented the fix and verified the correct behaviour with beckhoffSim.

Fixes will be verified next Monday with the tunnel system.

Have a nice weekend

Alessandro

ps: For future reference:

beckhoffSim  tags/1.1.0-1.4  (implements the recent plc behaviour (framework tag N/A Could not find tobias))

beckhoffDevices tags/2.0.1-1.4 hangs

just for reference ... here are pictures and schematics of the racks which are involved in the current commissioning.

Tobias Freyermuth and me worked on the system and as of last night, we found two new issues between Karabo and the PLC interlock:
 - one is a Karabo issue from the Interlock PLC interaction, the Karabo device waits for a PLC response that does not come when the PLC is interlocked (i.e. Karabo wants to open a valve but the PLC correctly refuses and ignores the command)

 - one is a PLC issue, the interlock is not triggered in all cases after testing (e.g. a ion pump out of set point does not closes a gate valve closure as specified).

The first one was reproduced with the BeckhoffSim simulation. It can therefore be fixed by CAS without dependencies from AE (except for the next integration test).

Dear Colleagues,

in the future we would like to use this mechanism to record and exchange information that concerns the work done within the context of this task force. Please use this generously. We shall also put a link to the minutes after each weekly meeting.

regards,

Tobias
