I think the main problem is that this line:

serialTest_DBD += drvAsynIPPort.dbd

needs to be changed to:

serialTest_DBD += asyn.dbd drvAsynIPPort.dbd

asyn.dbd is where the asynRecord and lots of other things are defined.

 

Another issue is that it looks like you are trying to use the drvAsynIPPort driver to talk to the NI GPIB-ENET/1000.  It don’t think that will work.  Most Ethernet to GPIB devices are VXI-11 compliant, and so can use the EPICS VXI-11 driver.  But the NI GPIB-ENET is not VXI-11 compliant, it uses a National Instruments proprietary protocol.

 

There was a tech-talk thread that discussed this several years ago.  You should look at all of the messages in this thread.

The final message was an offer to contribute a new driver for the National Instruments VISA library, but as far as I know that never happened. We could follow up on that if it is important for you.

Subject: Asyn support for GPIB-ENET

 

Hi Mark,

 

I’m trying to build asyn support on windows-x64 to use with GPIB over Ethernet (NI GPIB-ENET/1000).

I have installed the NI’driver for GPIB-ENET/1000. It works well.

 

I refer to the method on the web page https://epics.anl.gov/modules/soft/asyn/AsynRecordControl/AsynRecordControl

 

1. Create a new application
   mkdir serialTest
   cd serialTest
   makeBaseApp.pl -t ioc serialTest
   makeBaseApp.pl -i -t ioc serialTest
2. Add ASYN support.
   Edit configure/RELEASE.
   ASYN=$(SUPPORT)/asyn-R4-37
   
   Edit serialTestApp/src/Makefile and add two lines. 
   serialTest_DBD += drvAsynIPPort.dbd
   serialTest_LIBS += asyn
   
   Edit serialTestApp/Db/Makefile and add a line:
   DB_INSTALLS += $(ASYN)/db/asynRecord.db
   
   Edit iocBoot/iocSerialTest/st.cmd.
   
   #!../../bin/windows-x64/serialTest
   
   < envPaths
   cd ${TOP}
   
   ## Register all support components
   dbLoadDatabase("dbd/serialTest.dbd",0,0)
   serialTest_registerRecordDeviceDriver(pdbbase)
   
   ## Configure devices
   drvAsynIPPortConfigure("L0","192.168.21.98:5000",0,0,0)
   
   ## Load record instances
   dbLoadRecords("db/asynRecord.db","P=norum:,R=asyn,PORT=L0,ADDR=27,IMAX=100,OMAX=100")
   
   cd ${TOP}/iocBoot/${IOC}
   iocInit()
3. Build the application (run gmake from the application top directory).
   No errors.
4. Start the IOC
   cd iocBoot/iocserialTest
   ../../bin/windows-x64/serialTest st.cmd

The following error occurred:

..........

dbLoadRecords(“db/asynRecord.db”,...............)

Record “norum:asyn” is of unknown type “asyn”

...........

This problem may be because I didn't add the asyn module correctly.

But I don't know how to modify it.

 

Could you give me any advice?

 

Thanks,
