Hi John,

 

Which iocBoot/iocXXX are you running, or using as an example?  I believe Matt has updated the files in iocGSECARS-4Channel so you should probably use those as your model.

 

The ROI time-series PVs changed with recent versions of areaDetector, and all of the other SCAROI.cmd files are old:

First, thanks to Matt Newville and Mark Rivers for your help in getting my XSPRESS3 IOC running. (I'll post later it it actually fixes our original problem.)

 

I have two questions related to the IOC:

 

On IOC start-up I get 48 messages (6 channels x 8 SCAs) of this type:

 

devAsynFloat64Array::initCommon, XSPRESS3:C1SCA1:TSArrayValue connectDevice failed asynManager:connectDevice port XSP3.C1SCA_TS not found

devAsynFloat64Array::initCommon, XSPRESS3:C1SCA2:TSArrayValue connectDevice failed asynManager:connectDevice port XSP3.C1SCA_TS not found

devAsynFloat64Array::initCommon, XSPRESS3:C1SCA3:TSArrayValue connectDevice failed asynManager:connectDevice port XSP3.C1SCA_TS not found

.

.

.

 

 

Plus this message:

 

2020/01/28 12:57:33.650 asynNDArrayDriver:readNDAttributesFile: unknown attribute type = INT for attribute CHAN1DTCFLAGS

 

 

Any advice would be appreciated.

 

Thanks,

 

John

Matt,

 

Thanks, I knew nothing about the  /dev/shm/xsp3*  bit. That did the trick. The IOC now starts and connects.

My IOC is built but I have trouble with xspress3config, note that my Xspress3 chassis has more than 4 channels.

 

I changed the Y_SIZE (max_channels)  in xspress3/iocs/xspress3IOC/iocBoot/iocxspress3-4Channel/st.cmd to 6

 

xspress3Config("XSP3", "6", "1", "192.168.0.1", "16384", 16384, "4096", 0, 0, 1, 0)

 

but I get messages from xsp3_config that I don't understand

This error appears to come from the Quantum supplied library (?)

 

I don't know what it is trying to tell me

 

John

 

Do you have and are you loading Xspress3 settings and calibrations files for 6 channels or for 4 channels?  Somewhere in the IOC startup, you have to define where these settings files are, with something like

     dbpf("$(PREFIX)det1:CONFIG_PATH", "/home/xspress3/xspress3_settings/current/")

 

And these settings really should be for the correct number of channels.  If you change the number of channels I believe you need to remove the shared memory files in /dev/shm/xsp3*.  These files will be re-created when the IOC restarts the xspress3 server.
