Looking for help with PVADriver IOC #14

Closed LeeYangLBLBCS closed 1 year ago

MarkRivers commented 1 year ago

I just configured the ADSimDetector to generate images, enabled the NDPluginPva, and started a pvaDriver. They are able to communicate fine.

In your screen shot the text entry widget for the PV Name is empty, although there is a readback. What happens if you type 13SIM1:Pva1:Image there and press Enter?

This is what my screen looks like image

In my case I did not type the PV name, that was remembered by autosave. Note that it does appear in the text entry widget. All I did was start acquisition in both the SIM and PVA drivers.

Comparing the MEDM screens, my ADPvaDriver.adl does not match yours. The other two on the left, simDetector.adl and NDPva.adl look correct.

MarkRivers commented 1 year ago

Note that you are getting these 2 errors after iocInit:

2023/03/23 22:36:22.183 pvaDriver::connectPv exception initializing monitor: 0 or empty channel name
2023-03-23T22:36:22.214 ServerContext configured with no Providers will do nothing!

Your commonPlugins.cmd has these lines commented out:

# Optional: load NDPluginPva plugin
#NDPvaConfigure("PVA1", $(QSIZE), 0, "$(PORT)", 0, $(PREFIX)Pva1:Image, 0, 0, 0)
#dbLoadRecords("NDPva.template",  "P=$(PREFIX),R=Pva1:, PORT=PVA1,ADDR=0,TIMEOUT=1,NDARRAY_PORT=$(PORT)")
# Must start PVA server if this is enabled
#startPVAServer

You don't need to load the PVA plugin if you don't want it, but I think you need to uncomment startPVAServer line, or add that line to st.cmd.

Your ADPvaDriver.adl screen, in the pvaDriver section, shows a (PVA) PV name of 13SIM1:image1. Might that be 13SIM1:Pva1:Image instead? That's what my ADSimDetector instance publishes. (My IOC prefix is ad: while yours is 13SIM1:, here is my console):

BTW, Mark's screen also shows the 13SIM1:Pva1:Image PV name.

LeeYangLBLBCS commented 1 year ago

thnaks - that fixed the problem. set PVName=13SIM1:Pva1:Image

PVAServer is started on the ADSimDetector IOC (shown below). Does it also need to be started on PVADriver IOC? The log I showed was for PVADriver IOC, where "startPVAServer" was commented out. image

MarkRivers commented 1 year ago

I think I was wrong about needing to start the PVA server. That is only needed for NDPluginPva (which is a PVA server), not for pvaDriver (which is a PV access client).

prjemian commented 1 year ago

I agree. You should start the PVA server only if you want your PVADriver IOC to be a relay (mirror, republisher, gateway, whatever) for the 13SIM1:Pva1:Image. I can imagine a few circumstances you might want such a relay:

prjemian commented 1 year ago

Imagine this network topology:

[ADsimDetector IOC]  [pvaDriver IOC]
[camera IOC]    -->  [relay IOC] --> client(s)
[camera subnet]          |         [client subnet]

The relay IOC has access to PVs from IOCs on both the camera subnet and the client subnet. The client subnet PVs could be additional metadata to contribute (via an attributes.xml file) to the image republished from the relay IOC.
