Modes of operation


What did we learn so far? (1/3)

Development Gas racks and software can be prepared in parallel Simplified HW drawings were necessary for user panels SW was tested in the lab without the gas HW ready

Process control Validation of UR states, alarms, commands, etc Validation of PLC code design Validation of the UNICOS concept for gas control UNICOS not easy to start with!



PVSS UNICOS Beta version,- but most of functionality available (~80%) Validation of window layers, navigation menus etc… Long way to go for trending !!!

Operation Common look and feel of all Process Control Objects (PCO) Access of objects in Auto/Manual mode Recipes for constants, alarms and parameters FSM based operation



CommissioningAfter short introduction we were able to

operate and fine tune process parameters without the help of the developers

Easily understandable menu structures and concepts of operation

FAST! Took only about 1 week!


Future plans

Alice TPC Remaining Racks System integration

In 167 with dummy volume Validation of interaction UR identification for top module

UNICOS Porting to UNICOS PVSS release (before system

integration)


GCS frameworkOnce developed, ALICE TPC will be ported to

this gas frameworkRem: Some gas framework components are

already used Low level objects in PLC and PVSS Synoptic of PVSS Recipes…


Conclusion

The first “Vertical Gas Slice” with final architecture was successfully implemented and tested. (Visits welcome)

We validated: URD, UNICOS for gas, PLC code generation, PVSS, operation issues, PID regulation etc..

Started development of Gas Frame Work with the experience gained
