Re: an IOC based on asynPortDriver

Please send the complete output when you start the IOC.

After the IOC boots type this command at the iocsh prompt:

asynReport 1

I assume this file is your driver, derived from asynPortDriver:
SHINE_SRCS += SHINE.cpp

Does it define the SHINEConfigure iocsh command?

Do you get an error after this line when you start the IOC:

SHINEConfigure("testAPD", 1000)

Subject: an IOC based on asynPortDriver


Dear Sir,


I have an IOC based on asynPortDriver.

the st.cmd is:

--------------------------------------------------

cd "${TOP}"
dbLoadDatabase "dbd/SHINE.dbd"
SHINE_registerRecordDeviceDriver pdbbase
SHINEConfigure("testAPD", 1000)
dbLoadRecords("db/SHINE.db","P=SHINE-BI:,R=,PORT=testAPD,ADDR=0,TIMEOUT=10000")
#dbLoadRecords("db/asynRecord.db","P=SHINE-BI:,R=,PORT=testAPD,ADDR=0,OMAX=,IMAX=")
########## AUTOSAVE ##########
set_requestfile_path(".")
set_savefile_path("/home/EPICS/","autosave")
save_restoreSet_IncompleteSetsOk(1)
save_restoreSet_DatedBackupFiles(0)
set_pass0_restoreFile("shineioc.sav")
###########################
cd "${TOP}/iocBoot/${IOC}"
iocInit
create_monitor_set("shineioc.req",10,"P=SHINE-BI:")


-------------------------------------------------

When I start the IOC, all PVs display an error message such as:

devAsynFloat64::initCommon connectDevice failed asynManager:connectDevice port testAPD not found

devAsynInt32::initCommon connectDevice failed asynManager:connectDevice port testAPD not found

Then, when I caget their values, they are all 0.


For example:

record(ai, "$(P)$(R)BPM_X")
{
   field(DTYP, "asynFloat64")
   field(INP,  "@asyn($(PORT),$(ADDR),$(TIMEOUT))BPM_X")
   field(SCAN, "I/O Intr")
}

+dbpr, the message is:

AMSG:               ASG :               DESC:               DISA: 0
DISV: 1             NAME: SHINE-BI:BPM_X                    NAMSG:
RVAL: 0             SEVR: INVALID       STAT: UDF           SVAL: 0
TPRO: 0             VAL : 0


Is there a file missing during compilation?
