New feature for final system

Improved Hardware description from Hardware tree, more detailed features for all components (boards, temperature, MAO, rack and BCs), easier management of all kind of problem happened during the MTCC .

Positive performance tests in 904 using the final hardware for one wheel regarding configuring, starting up and db access operations.

Additional feature for each wheel, possibility to plot simultaneously the worst six chamber. Additional information about the status of cooling, cavern environmental conditions and magnet status.

DCS news

We are migrating the entire structure to the DCS final PCs in P5. All DCS PCs have been put in place, configured and ready for working.

From HV/LV point of view, the first step for W+2 test was deeply focused on the hardware setup of the entire system.

All chain components has been configured and tested successfully.

The HV Mainframe has been installed, configured and now works properly in USC55. This mainframe is temporarily shared with LV to allow testing.

The Next step, after creating all the right links and setting the right configuration for HV,LV and T boards, is to upload the setup configuration into Db. Only after this, PVSS is able to retrieve the config from db and start to control the entire system.

Databases Configuration DB: A version of Configuration PVSS db with all hardware structure and working parameter has been created on devdb for W+2. Next step is to move on OMDS db.

Condition DB: More hardware information added on db from hw point of view, optimized thresholds for main channels parameter (Vmon, Imon, I0,V0,status,temp) and from hardware component (Board temperature, FSM status, HW status)

Regarding OMDS db resources, the idea is to use a common db only for PVSS data, both for configuration and condition.

Additional table and view to simplify and speed up the communication with external software.

Conclusion

The entire system fully responses to the last version of the official CMS DCS guidelines, required for the integration to the Central DCS.

First PVSS DCS application version for W+2 available when the final hardware configuration will be ready (after cabling T sensor ~ 1 week). Ready to be used from not expert from the second half of May.

Global DCS commissioning is foreseen from the half of Jun.

Regarding Endcap, no upgrade has been done from the MTCC for qualified manpower missing.
