PLC Integration

PLC Integration

• Franck Di Maio
• AB/CO/FC

2
Outline

• Hardware architecture
• Software
• FESA vs GM
• Target for 2004

FEC Hardware

• Front-end computers are
• VME-based, PPC CPU (from CES), LynxOS, Timing
  Receiver (CTRP in 2004).General purpose.
• PC-based (3U rack), Intel CPU, LynxOS (Linux
  later), Timing Receiver (CTRP also)Only for
  Gateways (FIP).
• cPCI-based, Intel CPU, LinuxOnly for OASIS
  (analog signals)
• Any Linux system running front-end software

4
IP Gateways

• For IP gateways (as for PLC), 2 possibilities
• FEC local LynxOS system with timing
  reception, preferably on the same Ethernet
  Switch. If synchronization with timing is
  required (ex Linac RF).
• Server central Linux system on Technical
  network (later with timing reception).

(timing)

• 2 types of Request
• Simple/generic interfacing a data variable with
  generic treatment (for specialist)
• Specific code (for operation)

FESA

• The Dark Age
• BISCoTO _at_ SL/BDI (and AB/BDI)
• GM _at_ PS/CO (and AB/CO/FC) ? PLC integration
• The FESA era
• BISCOTO -gt FESA 1.0 (from Nov 03)
• GM -gt FESA 2.0 (from June 04)
• GM-gtFESA impact
• Composite property (ex CMD) for Java Application
• Productive C development environment for FE
  software.
• Same for CO and BDI.

2004

• With
• Data defined in PLC
• Specs of the properties for application (in
  modern SL language, please!)
• We can make FESA classes before the shutdown
• We will maintain only generic pieces
• We wont provide backward compatibility for
  Nodal/Data-module/SL-Equip
