EPICS test database#
To test the program during its development, a test database (test.db) was prepared. The database creates two PVs:
pvMail:triggerthe PV to watch
pvMail:messagethe message to be sent
starting: softIoc#
Start the database by adding it to an existing EPIC IOC configuration
or by starting a soft IOC using the softIoc program softIOC
from EPICS base.
Here is an example of how that looks from a Linux command shell:
1$ softIoc -d test.db
2Starting iocInit

Note
Here, the shell prompt is signified by the $ symbol.
watching: camonitor#
Once the EPICS IOC is started and the PVs are available,
it is possible to watch them
for any changes from the command line using the camonitor camonitor
application from EPICS base:
$ camonitor pvMail:trigger pvMail:message
pvMail:trigger <undefined> off UDF INVALID
pvMail:message <undefined> pvMail default message UDF INVALID
Note
Do not be concerned about the UDF INVALID notices, they will disappear
once the PVs have been written to at least once.
changing a PV: caput#
You can test changing the value of the trigger PV using the caput caput
application from EPICS base:
$ caput pvMail:trigger 1
Old : pvMail:trigger off
New : pvMail:trigger on
changing a PV: dbpf (in the IOC shell)#
You can change the value of the trigger PV using the dbpf dbpf
command in the IOC shell:
$ dbpf("pvMail:trigger", 1)
"on"
$ dbpf("pvMail:trigger", 0)
"off"
