EPICS and CLS September 18, 2009
Controls Environment • Common Target Processors • Intel x86 (RH 7.2 for VME apps, SL 4.x for OPI) • Mxscaleb (Moxa 7408, 8 serial processors, Linux) • Motorola 68360 25MHz (EROC)
Controls Environment • Operating Systems • Linux Red Hat 7.2 • Scientific Linux 4.X • Moxa Embedded Linux • RTEMS (Motorola 68xxx and Intel x86) • Windows XP with Cygwin
Common Tools • EPICS • edm • matlab • gtk+ based library (no longer supported) • Qt+EPICS widget library • Less Common: • Root • Python • spec
Development See 7.1.39.1 rev ??? Using css2400-103 for development • makeBaseApp.pl –t iocmyproject • makeBaseApp.pl –i –t iociocname Development Details
Deployment • /iocApps/SYSTEM/IOCNAME/APPNAME • /iocApps/SYSTEM/APPNAME (symbolic link) • /etc/init.d startup script SYSTEM – e.g. 06B1_1_SXRMB_BL IOCNAME – e.g. IOC1606-022 APPNAME – e.g. Motors In general the bin, db, dbd, and iocBoot directories are installed with required files
Deployment - libraries • use $EPICS_LOCAL/drivers when installing Library_name Library_version lib Linux-x86 libNAME.a libNAME.so.X.Y libNAME.so.X.Y.Z libNAME.so include NAME.h
Deployment - libraries Screens NAME.tpl OPI NAME.tpl templates NAME.tpl NAME.db NAME_morestuff.db dbd NAME.dbd
Deployment - OPI • /home/control – for Linac/BR1/SR1 operation (beware of DEVELOPMENT vs. PRODUCTION) • /home/beamline – for common beamline applications and libraries • /home/hxma (e.g.) – for applications specific to the given beamline
Documentation! • Documentation Procedure – \\canopus\common\Library_and_Reference\Document_Control • Also available from http://teamsite under “Documents -> Approved Documents” • Wiki (http://wiki.clsi.ca)
What is EPICS? • EPICS Overview
What is Channel Access? • Channel Access is the Software Bus for EPICS Application communication • Channel Access
Records and Fields • Records are common definitions of a collection of fields. New record types are rarely developed at the CLS • In the simplest case, a Field is the minimum Channel Access data communicated • Device drivers are designed to process a record when a field updates (output) or when hardware values have been read (input)
Record Processing • Records, Devices, and Drivers • Databases, Part 1
Record Types • Databases, Part 2
