RPC DCS Status I. N. F. N. Naples • RPC muon System for DCS is developed in the form of a hierarchy where every object is represented as a node of the tree, following CMS structure. • Its architecture has been developed using the framework components. • All the panel actions have been developed with custom scripts. • Naming and color framework conventions are respected !! • All structures have been tested using in the first time an ad hoc simulator and then the SY 1527 Power Supply. • Alarm conditions on HV and LV devices have been set and each channel has a summary alarm. • The state of the machine aren’t connected; the conditions for pass from a state to another hasn’t been chosen yet. 11/29/2020 P. Paolucci & G. Polese of Napes I. N. F. N. 4

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 State Machine has been developed and test during Feb 05 with the JCOP/CMS experts. 11/29/2020 P. Paolucci & G. Polese of Napes I. N. F. N. 5

HV Wheel node I. N. F. N. Naples • The wheel panel contains the infos about the parent and the children nodes with the relative state condition. • The status of every RPC is defined by the framework colors for the alarm status. • Wheel name is an ext. variable • All objects are clickable. An overview of all device element is obtained clicking the Set/Monitor button. 11/29/2020 P. Paolucci & G. Polese of Napes I. N. F. N. 6

Set/Monitor button I. N. F. N. Naples Tab menu for select device type 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, Over. Voltage, Under. Voltage, Ramp. Up, Ramp. Down 11/29/2020 P. Paolucci & G. Polese of Napes I. N. F.

Wheel Global setting I. N. F. N. Naples The Global settings panel set the values of all the channels of the wheel for 11/29/2020 the select type P. Paolucci & G. Polese I. N. F. N. 8 of Napes

Channel Details I. N. F. N. Naples Left Click Details panel shows detailed info of the selected channel, its position in the wheel, alarm conditions, the VMON/IMON plots and allow to set 11/29/2020 P. Paolucci & G. Polese history I. N. F. N. 9 of Napes every single parameters of this channel.

Sector Node I. N. F. N. Naples The Sector node has 8 children (RPC chambers). Some parameters and the status of each RPC are shown here. 11/29/2020 P. Paolucci & G. Polese of Napes I. N. F. N. 10

Chamber Node I. N. F. N. Naples Summary alarm with possibility of masking whole chamber. • Fully description of each RPC’s devices. • Left Click on status box for mask/unmask each single element. • Simple Infos about temperature value and sensor status. 11/29/2020 P. Paolucci & G. Polese of Napes I. N. F. N. 11

Devices (Leafs) Set and Confirm values for all channel parameters Possibility of mask/unmask and acknowledge each single parameter or all together Additional panel for switch the state of the channel and load settings from the hardware 11/29/2020 I.

To be Done I. N. F. N. Naples • Test with the Configuration DB has been done in Feb 05 and now we have to: – work on the config. DB structure – use the Mass configuration when possible. • Design a temperature device panel and choose main parameters to monitor • Migrate to the EASY hardware • Test the PVSS prototype in the commissioning and during the Cosmic challenge. • Export our system to the Endcap DCS 11/29/2020 P.
