Next Linear Collider Test Accelerator RF Controls
Software Status Report
This page provides the software development status report for NLCTA RF
as of June 27, 2001.
All VME and Allen-Bradley modules installed
Order 1 UPS 1400. This will be used for the VME crates and terminal server
Order 1 XYCOM 203/293 Counter Module w/quadrature - $1000.00
EPICS device/driver/record support
Kernel modifictaions for powerPC
Build EPICS source for the powerPC processor (base,site,app)
Download VxWorks Boot image into the powerPC onboard FLASH
Timeout software added to the CaenV265ISR. (testing needs tobe done)
Generic EPICS VME Card Record added. This provides module information such
as status, bus address,status register,etc. This record is used for diagnostic
Merged Lecroy 1176 TDC Waveform device support into VME Card Record.
Subroutine record for accelerator structure logic
EPICS and SCP Displays
Accelerator structure logic
EPICS Channel Archiver and VME History Buffering
Add fast data acquisition pv's to EPICS displays.
Created new EPICS displays and strip charts for fast data acqusition.
Created SCP Correlation Plots (Toni)
Miscellaneous VMS Work
Setup and configuration files
Archiving channels for charge integrating adc: ENERGYON,ENERGY,ENERGYMIN,ENERGYMAX,ENERGYAVE
Work In Progress
CaenV265 parts from should arrive at Wiener, the US distributor this week.
Andreas Ruben will overnight the parts to SLAC when they arrive at Wiener.
A solution to the bad channel data on the positive Caen V265 modules has
been found by Jeff Olsen and Mike Brown. A fix is currently being implimented.
Determine if the bus speed on the Motorola MVME2700 can be changed in software.
Set database limits (alarm and operating limits) in databases templates.
Web page documentation
Add fields to VME Card Record to support 16 individual inputs
Add CaenV265 Record fields to account for timeout errors: TCNT, OCNT,
Add error metering for missed pulses
Complete database work for fast data acqusition
CaenV265 channel calibration and database coefficient update.
Work To Do
Sequence for ramping DAC
Modifiy existing driver and device support for Joerger VTR 812 analog digitizer
for the VTR 812/10
VMS Configuration Files
EPICS Display help files
Need to setup hardware reset of VME crates. This will require two IDOM
Load test with powerPC running EPICS fast data acquisition software
Test CaenV265 Record fields: MRST,FLSH and LCK
Connect channel on VMIC 4100 DAC to voltmeter to check output
Connect TDC channels to real data.
Connect hadwar to a start (pdu) and stop (do) trigger so that the
time between when the 60Hz gate is issued and the database lockset has
completed. The goal is to determine how much time we have before the next
get is expected.
Hard disks for data storage (???)
Spare VME modules (???)
