RT architecture for System Admin

Required software to run real time (RT) system as standalone (Gentoo)

• mbuf.ko in /lib/modules/2.6.34.1/kernel/drivers/mbuf/
• x1x14fe.ko
• x1x15fe.ko
• epics IOC
• awgtpman
• nds
• daq

Startup procedure

• /etc/conf.d/local.start to call /opt/epics-3.14.9-linux/base/bin/linux-x86/caRepeater and /lib/modules/2.6.34.1/kernel/drivers/mbuf/mbuf.ko
• nds, daq as respawn: /etc/inittab to call start_nds and start_daqd in /opt/rtcds/tst/x1/target/fb
• RT model name: /etc/rtsystab
• /etc/rc.local (or startx1x14, startx1x15 in /opt/rtcds/tst/x1/scripts/)
  • EPICS: /opt/rtcds/tst/x1/target/x1x14/x1x14epics/startupX1
  • RT core: /opt/rtcds/tst/x1/target/x1x14/scripts/startX1rt
  • awgtpman(testpoint): /opt/rtcds/tst/x1/target/gds/awgtpman_startup/awgtpman_x1x14.cmd

Other useful setting files

• daq: /opt/rtcds/tst/x1/target/fb/master, /opt/rtcds/tst/x1/target/fb/daqdrc
• ??? /etc/xinetd.d/chnconf, /etc/xinetd.d/diagconf, /etc/xinetd.d/leapconf

Applications to check RT system running

• medm: for epics, burt
• dataviewer: for tp channel, DAQ channel
• diaggui: for tp channel, DAQ channel

Useful commands to check RT system running

• dmesg
  lsmod
  diag -i
  ps -ef | grep nds
  ps -ef | grep daq
  ps -ef | grep awg

log files

• dmesg
• diag -i
• daq: /opt/rtcds/tst/x1/target/fb/logs/daq.log.XXX
• nds: /opt/rtcds/tst/x1/target/fb/logs/nds.log.XXX
• awgtpman: /opt/rtcds/tst/x1/target/gds/awgtpman_logs/x1x14.log
• awgtpman: /opt/rtcds/tst/x1/target/gds/awgtpman_logs/x1x15.log
• RT core: /opt/rtcds/tst/x1/target/x1x14/logs/log.txt
• epics: /opt/rtcds/tst/x1/target/x1x14/x1x14epics/icoX1.log

Applications in workstation (Ubuntu)

• medm
• diaggui
• awggui
• dataviewer
• foton
• ezca...
• tds...
• striptoor
• dmtviewer
• ligotools

Useful terminology

• nds: a software to control data stream
• daq: data acquisition
• testpoint: a point to see fast data stream
• testpoint channel: channel name for fast data stream, a test point is used when a channel name is called.
• DAQ channel: reserved channels for testpoints and the date will be stored to storage drive. Test point is not used when the channel name is reserved.
• epics channel: slow channels
• awg: arbitrary wave form generator
• awg channel: An excitation point is used when the awg excites a awg channel
• gds, DTT: FFT spectrum analyzer, network analyzer
• medm: EPICS GUI mainly used as human interfaces
• foton: digital fileter conposer
• dataviewr: slow but many channel oscilloslope
