4. RPC DCS software status I
All the parameters and variables (HV, LV and T) of the CAEN mainframe SY1527 are linked, by OPC server, to a set of PVSS datapoint through of the Framework configuration facilities.
Its architecture has been developed using the PVSS II and SMI++ toolkit in the JCOP framework.
PVSS II version 3.0 and Framework release 2.0.9
RPC DCS is developed as a hierarchy where every object is represented as a node of the tree, following the CMS structure.

RPC FSM structure
Each single element of the structure, in the FSM approach, is a different parts of the detectors, structured as logical software units, arranged in a tree-like structure.
Each logical unit is characterized by a set of well defined states.
The RPC states machine is not yet in place but the structure is ready and it will be implemented as soon as possible

6. RPC DCS software status II
All the panel actions have been developed with custom scripts.
Naming and color framework conventions are respected !!
All structures have been tested using, in a first time, an ad hoc simulator and then the SY1527 Power Supply .
Alarm conditions on HV and LV devices have been set.
PVSS archiving has been used waiting for the framework interface with Oracle.

Main RPC DCS panel
The RPC panel is under construction and it will include some sub-panel to set values for the whole RPC system;
The status of the RPC node is also our top level status;
Access to the Wheel node (panel).
We are investigating the possibility to set alarms on some datapoints (Imon, Vmon….) where the ranges are related to other datapoints (I0set, V0set…)

HV Wheel node
The wheel panel contains info about the parent and the children nodes with the relative state condition.
The alarm status of every RPC is defined by the framework colors.
Wheel name is an external variable
All objects will be clickable.
The Set/Monitor panel provide the possibility to give a look at all the wheel channels.

Tab menu for select device type
The most relevant parameters and the relative conditions are shown here.
The status of each channel has been set with the relative color:
OK, Tripped, Overcurrent,OverVoltage,UnderVoltage,RampUp,RampDown

Wheel Global setting
From the Global settings panel it is possible to set the values of all the HV and LV channels of the wheel and switch ON-OFF all the channels of the selected wheel.

To be Done
A PVSS prototype is almost ready (dec 04) and is in test with a SY1527 (HV and LV boards) system;
An EASY system (HV, LV and ADC) has been installed in Naples in November 04 and is under test with LabVIEW;
Move to the EASY hardware system (when ??);
Implement the RPC State Machine (Jan 05);
Thing about the Archiving and the Mass configuration;
Be ready for the RPC DCS period to spend at CERN with the JCOP people (March 05)
