Hi Petra,

 

Ø  epics> 2021/05/11 09:38:32.320 L0 -1 autoConnect could not connect: Can't connect to 10.32.192.132:2101: Connection timed out

There is no error message when those asynSetTrace commands were executed.
Then it must be another thing.
I cannot clarify the one-time message: "autoConnect could not connect ..." I ignored that.
Because drvAsynIPPortConfigure("L0","10.32.192.132:2101",0,0,0) does not cause an error and with netstat I can see that the IOC is connected with the hardware and I get an answer when I do caget melba_020:wf:on_get.
But when the hardware is not properly connected to the IOC, then it is obviously, that asynSetTrace doesn't work.

drvAsynIPPortConfigure will not give an error message even if the device is not reachable.  Because you have set the noAutoConnect flag to 0, which is normal, asyn will periodically try to connect to the device in case it become reachable.

The asynSetTrace commands will not give an error because the asyn port does indeed exist, even if it is not yet connected to the device.

The “autoConnect could not connect” message is the key.  It means the asyn IP port driver could not open a socket to the device.

You will get an answer when you do caget on the waveform record.  But does it actually contain the response you expect?

Here are things to try:

After iocInit type this command:

asynReport 1 L0

That will show if asyn thinks it is connected to the device.

If it is not connected then stop the IOC and in a Linux shell type this command:

telnet 10.32.192.132 2101

Does that connect to the device, or does it fail?  If it fails then the device is indeed not reachable.  Perhaps there is a firewall blocking it, or something else.

Hi Petra,

If you configured your IOC as shown in that document then it should not matter which version of base you are running.

I add

asynSetTraceIOMask("L0",-1,0x2)

asynSetTraceMask("L0",-1,0x9)

to st.cmd, but nothing happens.

By "nothing happens" does that mean you got an error message when those asynSetTrace commands were executed, or just that there was no output from asynTrace.

Can you send the complete output when the IOC starts up and runs for several seconds?

Mark

Subject: asynSetTrace

Hello,

I want to use

asynSetTraceMask(portName,addr,mask)

asynSetTraceIOMask(portName,addr,mask)

I used EPICS 3.14.12.5 and I had no problems.

Now I use EPICS -7.0.3.1.

I configured my IOC like described in

https://docs.epics-controls.org/projects/how-tos/en/latest/getting-started/creating-ioc.html<https://docs.epics-controls.org/projects/how-tos/en/latest/getting-started/creating-ioc.html?highlight=trace#creation-of-an-input-output-controller-ioc>

I add

asynSetTraceIOMask("L0",-1,0x2)

asynSetTraceMask("L0",-1,0x9)

to st.cmd, but nothing happens.

My IOC is working.

Could it be that there is something to add to the xxxSupport.dbd file

registrar(drvAsynIPPortRegisterCommands)

registrar(drvAsynSerialPortRegisterCommands)

something like registrar(drvAsynSetTraceCommands)?

Thank you for your efforts!

Best regards

Petra
