Overview

• UF/PNPI Hardware Setup• UF/PNPI Software Setup• Current Software Situation• Future Development

Hardware Setup

• PCI Hostcards• Primary Power Supply (Matsusada AU-5P60-LF)• Master Boards• Remote Distribution Boards

Hostcard Issues

• Currently PCI 5V• PCI 3.3V version in

testing• Possible change to a

USB solution

Software Setup• FPGA Code• Device Driver• DIM Server• PVSS Module

DIM Communication

• “Communication system for distributed and mixed environments.”

• “Provides a network transparent inter-process communication layer.”

• Server / Client architecture.• The Server provides Data Services and

Command Services.

PVSS

• SCADA system chosen for LHC control systems

• JCOP Framework provides tools and guidelines

• Uses tree-like data structures

UF/PNPI DIM Server

• Communication strategy chosen specifically to work well with PVSS and the JCOP Framework

• Connects to the Device Driver• Auto-detection of Hardware• Setup of Hostcards, Boards/Modules and

Channels• Voltage and Current calibration• Publication of DIM Services

UF/PNPI DIM Server• Hostcard

– Data: Read Settings– Command: Write Settings

• Board/Module– Data: Read Settings– Command: Write Settings

• Channel– Data: Read Voltage and Current– Data: Read Settings– Command: Write Settings

UF/PNPI DIM Server

• Acts on DIM Command Services• Updates DIM Data Services when new

data is available• Current and Voltage Deadband• User settable Update Rate

UF/PNPI PVSS Module

• “Framework Device”• Follows JCOP

guidelines• Similar setup as for

CAEN and Wiener• All Hostcards,

Boards/Modules and Channels represented

Future Development

• Implement Primary Power Supply• Perform thorough testing of a complete

system

Summary

• DIM Server with communication strategy suited for use with PVSS and JCOP

• JCOP Framework Device created• Hostcards, Master Boards and Remote

Distribution Boards are implemented• Primary Power Supply will be implemented

PVSS

• SCADA system• Chosen for LHC control systems• Good for scaling up• Uses tree-like data structures• Graphical interfaces• C style scripting

JCOP Framework

• Joint Controls Project for LHC• Provides common modules and tools for

control system design• Gives guidelines that should be followed

for control system design in the LHC
