RPC FSM Hierarchy
Since the last meeting:
The endcap is up to date with the barrel and the two systems are proceeding in parallel
Tests on CPU and RAM usage have brought us to reduce the number of CUs. Limiting to the top two levels. Possibility of using only wheels or disks in standalone mode as lower nodes.
Introduction of a new level in the hierarchy. This will allows a better partitioning of the system.
The two systems are under a single top node as required by the CMS DCS Integration guidelines. The two systems can also work standalone.

RPC DCS for MTCC
Since the last meeting:
Intensive (2 weeks) test with HW at 904 building induced us to perform Minor changes to the FSM schema
Redesign Hierarchy and distribution on more PCs.
We are investigating How distribute the HW component on more PCs and the resources needed.

15. RPC DCS Integration Status
We were successful in creating a first version of the CMS RPC sub-detector SUPERVISOR component using the tool provided by the JCOP framework. The RPC component contains both Endcap and Barrel trees, but it has been designed has two components that can work on different PCs.
We accessed the Configuration DB . We are able to read from and write in it (in a private Oracle DB) using custom scripts with Framework functions.
We still need to
- know the coordinates of the DB we are going to use for the CC and test the best way to access the DB (different solutions are possible)
- finish to prepare the hardware component (march 06)
- work on the condition DB
- temperature monitoring (waiting for JCOP FW)

16. CMS RPC Gas Monitor Frascati Group
A monitoring system of the RPC work point which is able to provide much faster and sensitive response than the CMS RPC system.
Monitor efficiency and charge continuously
If work point changes, alarm goes off and DSC systems (GC,probes, etc) verify what the change of work point is due to.

18. DAQ system for the CMS RPC Gas Monitor
The system must be integrated in the Slow Control (SC) of CMS RPC. This implies to follow the CMS standards for DAQ: PVSS or xDAQ
We are evaluating different solutions in order to minimize the effort in the integration with CMS Slow Controls
Our present option is to use a system fully based on PVSS both for P,T, RH and HV, and both for ADC, (+TDC...+ other VME module) readout based on VME standard
Standalone systems (PICO, ACQIRIS, etc) do not seem to offer the same versatility of a VME system and comparable performances
VME readout via PVSS ?
