EPICS access issues via DSC Module - Array Size Limitations

[DuaneVoy]

It seems that LabVIEW/DSC is not paying attention to the EPICS_CA_MAX_ARRAY_BYTES environment variable.  I have set it to a large value which works for caget and camonitor, but LV/DSC only allows me to read 4099 four byte floats in a single array.  If I ask for 4100 or more I get "Unknown Bad Quality" in the System Manager status.

Is there some way I can get larger array bounds?  I have some quite large arrays (20,000+ floats) that I must read and process.

Yes.  This is an issue.  The EPICS client I/O server does not read any Environment Variables.  In my case, it doesn't read EPICS_CA_ADDR_LIST, so I can not connect to our EPICS pv gateway, making it not possible to connect to any channels.  Has anyone solved this?

Thank you,

Eric

Hello,

Currently there is no workaround for this situation, but I can assure you that R&D is looking into it because there was CAR created for it by one of the R&D engineers. So I can assure you that it is being looked into.
