FCStatusDecoder assumes a single FC card, errors if multiple cards

[slwatkins]

I've been working with the decoders to validate the FC and ORCA files being created to ensure no data is lost, and the FCStatusDecoder errors at these lines when there are multiple cards being logged.

legend-daq2lh5/src/daq2lh5/fc/fc_status_decoder.py

Lines 78 to 86 in f32428e

	# FC card-wise environment status (temp., volt., hum., ...)
	tbl["environment"].nda[ii][:] = fcio.environment
	# FC card-wise list DAQ errors during data taking
	tbl["totalerrors"].nda[ii] = fcio.totalerrors
	tbl["linkerrors"].nda[ii] = fcio.linkerrors
	tbl["ctierrors"].nda[ii] = fcio.ctierrors
	tbl["enverrors"].nda[ii] = fcio.enverrors
	tbl["othererrors"].nda[ii][:] = fcio.othererrors

This is reproducible with, e.g., the tst file l200-p04-r006-tst-20230510T101033Z_FCIO_1.fcio, using the below code:

from daq2lh5.fc import fc_streamer

fc_file1 = 'l200-p04-r006-tst-20230510T101033Z_FCIO_1.fcio'

fcstr1 = fc_streamer.FCStreamer()
fcstr1.open_stream(fc_file1)
fcstr1.read_chunk()

which errors at the quoted lines, due to each value being either a list of lists or a list.

Would it be possible to produce a short test file to upload to legend-testdata? Maybe @ssailer has access to the L200 DAQ machine and knows how to do that?

@jasondet what do we need to do in order to fix this?

[ssailer]

I had a quick check: Only the first card is exposed, see legend-exp/pyfcutils#39
This is usually the MasterCard.

I have turned status decoding off for now while Simon updates the pyfcutils interface.

I closed the wrong issue 🤦‍♂️
