RPC DCS Status
I.N.F.N. Naples
The RPC DCS is divided in five partitions one per wheel.
Its architecture has been developed using the framework structure.
All the panel actions have been developed with custom scripts.
Naming and color framework conventions are respected !!
No alarm conditions on single channel parameters has been set up to now.
The state of the machine aren’t connected; the conditions for pass from a state to another hasn’t been chosen yet.

RPC FSM structure
I.N.F.N. Naples
Each single element of the structure is view as a node of a state machine, build as a hierarchical tree.
The nodes are (upper to lower): RPC- Wheel-Sector-Chamber- Channel
All nodes are object types and only the lower leaf is a device and is connected directly to a channel of the SY1527 Caen Power Supply.
At this moment the states machine is not defined and the structure is only for visualization of the system proprieties.

HV Wheel node
I.N.F.N. Naples
The wheel panel contains the infos about the parent and the children nodes with the relative alarm states.
The status of every RPC is defined by the framework colors.
Wheel name is an ext. variable
All objects are clickable.
Set/monitor
An overview of all channels is obtained clicking the Set/Monitor button.

5. Set/Monitor button
I.N.F.N. Naples
The most important 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

To be Done
I.N.F.N. Naples
Check script framework conventions;
Define the alarm conditions of HW channels and how to propagate them to the upper node;
Define the SM conditions and how to move from one to each other;
Implement the same structure for LV & T;
Develop the RPC (main) Node;
Thing about the Archiving and the Mass configuration.
