3. Major Effort Areas
Getting an accurate count of all devices
Naming devices (and extending SLC convention)
Aligning XTOD controls devices with LCLS global standards
Reviewing cost+schedule
Installing EPICS at LLNL

4. Counting Devices
Layout and instrument list has changed since original design
Original design was not “EPICS-aware”
Need block diagram or even one-line diagram to accurately define PLC, IOC and other controls- specific components
LCLS-wide standards are (just) now being set
All of above are basis for accurate cost+schedule

5. Will conform to (and extend) SLC conventions
Naming Devices
Will conform to (and extend) SLC conventions
Especially for “SLC-aware” devices
Allows uniform notation on spread-sheets, one-line diagrams, as well as EPICS configuration
Implicitly forces accurate counting

6. Safety must be engineered in
LCLS Global Standards
Safety must be engineered in
Commerical products are one way to ensure this (UL, CE, …)
Initial Q/A will take place at LLNL for many items

7. LCLS Global Standards…
Motor/Encoder chains:
OMS58 in VME+transition card+power “brick”: 3 vendors; extra box+cables; great reuse of EPICS practice; parts long-lived
Newport XPS single-box: turnkey; TCP/IP field- bus; new driver (and motor record?); rapid evolution of product likely
Other?

8. LCLS Global Standards…
Vacuum/Gas: Controllers & Architecture
“Smart” controllers + inter-controller wiring + serial to EPICS
Wiring complexity; less global integrity
“Dumb” controllers+PLC+ Ethernet/IP to EPICS
Global integrity; simple wiring
ControlLogix vs. FlexLogic
Trade-offs in cost, need for wire-centers, availability of EPICS driver

9. LCLS Global Standards…
Choices for Gauges
MKS-937A w/317-CEP and 422-CCG
15msec response option
Other?
Choices for Ion Pumps
Dual; Quad; ?
MPS-2
SafeCONN
Kaiser
StarCell

10. Reviewing Cost+Schedule
Accurate device count supports:
I/O hardware and cabling costs
Approx $200K to be added for master PLCs
Configuring+Commissioning Effort
Approx 1500 hours to be added for Tunnel
Fixed costs as well:
Server for LLNL prototyping
Licenses (PLC…)
Any new drivers

11. Borrow small VME crate, CPU, EVR and EVG from SLAC
EPICS at LLNL
Set up a server
RH Linux or MacOS X?
Keep CVS at SLAC
Intellectual property issue?
Borrow small VME crate, CPU, EVR and EVG from SLAC
Gas Attenuator prototype is first application
First use of PLC
Will train LLNL staff
