PVSS datapointsPVSS datapoints
Datapoints that correspond to hardware modules (channels, boards, crates, branch controllers, mainframe)
Datapoints that correspond to the chambers
Internal datapoints for the FSM for the OPC Server (communication with hardware) for the RDB manager (archiving of datapoint elements)
Alarms are activated for the datapoints and their elements

FSM treesFSM trees
Eleni Mountricha NTUA
One FSM tree is implemented for each partition
Hierarchy is set for the parts of the system (nodes and their children)
Commands and states propagate correctly

EndcapsEndcaps Both Big Wheels and Small Wheels (one for each side) are
incorporated to the system having both LV and HV modules Chambers in the Outer layer in side C are also incorporated
in the system but most LV modules are missing

Eleni Mountricha NTUA
PS DCS system is in use for the MDTs
Improvements are made in the PVSS/FSM part of the system to achieve higher stability of the system
Development is implemented concerning expert panels to achieve more efficient control of the system
MDT PS from the HV/LV modules’ point of view are reaching their completion
