Hi Lynn,

 

  • when i use the edm opi, i got the array error, but i do set  EPICS_CA_MAX_ARRAY_BYTES =6000000, why?

 

Are you sure you set EPICS_CA_MAX_ARRAY_BYTES both in the IOC server process and in the Channel Access client process?  Both need to be set.  In the IOC you can type this command to see the value:

 

epicsPrtEnvParams

 

The errors you are getting when EPICS_CA_AUTO_ADDR_LIST is not NO are expected because the IOC and client are running on the same machine with multiple NICs.  But setting that to NO and setting EPICS_CA_ADDR_LIST to one of the IP addresses should work.  I am not sure why that is not working.

Hi matt,

      Could I ask some more question.

Quetion 1:

when i use the edm opi, i got the array error, but i do set  EPICS_CA_MAX_ARRAY_BYTES =6000000, why?

 

type:  edm -x -m "P=XSP3_1Chan,CHAN=1,CHM=0,R=Proc1" /home/xspress3/epics/xspress3/xspress3App/opi/edl/xspress3_mcarois.edl

got :CA add event error('XSP3_1Chan:MCASUM1:ArrayData'): The requested data transfer is greater than available memory or EPICS_CA_MAX_ARRAY_BYTES

CA add event error('XSP3_1Chan:MCA1:ArrayData'): The requested data transfer is greater than available memory or EPICS_CA_MAX_ARRAY_BYTES

 

Quetion 2:

the xspress3_1Chan opi worked well both edm anc css. But when clicked "MCA1",  CSS blinking(conncet to disconnect, continue) and show the error:

 

2023-07-19 15:22:54.037 INFO [Thread 39] com.cosylab.epics.caj.CAJContext (searchResponse) - More than one PVs with name 'XSP3_1Chan:MCA1:ArrayData' detected, additional response from: /192.168.10.22:5064

Thethree ip was the pc. I think EPICS_CA_ADDR_LIST could resolve it. Then I modify EPICS_CA_ADDR_LIST, but still have the error.

I try several situation. and if EPICS_CA_ADDR_LIST = 192.168.0.1, CSS said: ......virtual circuit disconnect.

 

I think i was right (i means change EPICS_CA_ADDR_LIST ), but if i was right, i should get the right answer already.

Could you give me some advice.

Hi Lynn,

Hi Matt,

     Thank you.

     Two little question, could you help me with it.

     1) What the macro "IOC_Prefix" should be?

 

It does not need to be related to the same PREFIX for the IOC, but that is a pretty common choice.

So, maybe have

 

epicsEnvSet("PREFIX", "XSP3_1Chan:")

epicsEnvSet("IOC_PREFIX", "XSP3_1Chan:")

 

     2) Whichi is the acquire time pv? I browse pv list twice, didn't find the xspress3_1chan.opi did not have it.

 

I think I may not be sure what the OPI screens have, and don't have a working detector at the moment (APS shutdown).  

 

But, the "det1" areaDetector should have an AcquireTime and Acquire PVs, and also NumImages, 

 

    XSP3_1Chan:det1:Acquire         # start acquiring

    XSP3_1Chan:det1:AcquireTime # time for each "frame" / "images"

    XSP3_1Chan:det1:NumImages  # number of "frames" / "images"

 

That is, if you want a 10-second exposure, you can collect either 1 "image" for 10 seconds or 10 images for 1 second (or 1000 images for 0.01 seconds!).

XSP3_1Chan:MCA1:ArrayData will have the most recent "image", updating during collection of multiple "images", and 

XSP3_1Chan:MCASUM1:ArrayData ill have the sum of frames in the NumImages in the "run". 

 

Does that make sense?

 

--Matt
