EPICS Example IOC Applicaton
This page documents the first steps to an example IOC Application
Following the example given in chapter 2 section 2.2 of the
EPICS IOC Application Developer's Guide:
- Creation of a new IOC Application named
<My Example Application>
:
$>
mkdir <top>
$>
cd <top>
$>
$EPICS_BASE/bin/${EPICS_HOST_ARCH}/makeBaseApp.pl -t example <My Example Application>
$>
$EPICS_BASE/bin/${EPICS_HOST_ARCH}/makeBaseApp.pl -i -t example <My Example Application>
$>
make
$>
cd iocBoot/ioc<My Example Application>
- Starting the IOC:
(<Target>
(e.g.: linux-x86, or ${EPICS_HOST_ARCH}
), <My Example Application>
, <Top>
, <Epics Base Directory>
and <User>
have been replaced in the output )
$>
../../bin/<Target>/<My Example Application> st.cmd
#!../../bin/<target>/<My Example Application>
## You may have to change <My Example Application> to something else
## everywhere it appears in this file
< envPaths
epicsEnvSet(ARCH,"<Target>")
epicsEnvSet(IOC,"ioc<My Example Application>")
epicsEnvSet(TOP,"<top>")
epicsEnvSet(EPICS_BASE,"<Epics Base Directory>")
cd <top>
## Register all support components
dbLoadDatabase("dbd/<My Example Application>.dbd")
<My Example Application>_registerRecordDeviceDriver(pdbbase)
## Load record instances
dbLoadTemplate "db/userHost.substitutions"
dbLoadRecords("db/dbSubExample.db","user=<user>Host")
## Set this to see messages from mySub
#var mySubDebug 1
cd <top>/iocBoot/ioc<My Example Application>
iocInit()

- Listing the available PVs:
epics>
dbl
<user>Host:aiExample
<user>Host:aiExample1
...
<user>Host:xxxExample
- Any EPICS client should be able to see those PVs, e.g.:
$>
camonitor <User>Host:aiExample1
<user>Host:aiExample1 2007-08-09 10:42:00.037941 4 LOW MINOR
<user>Host:aiExample1 2007-08-09 10:42:01.039624 5
<user>Host:aiExample1 2007-08-09 10:42:02.041629 6 HIGH MINOR
