A new h1sqz model was installed (when all h1lsc0 models were restarted due to glitch). A DAQ restart was needed.

Adding h1edc DAQ status channels to h1edc

Dave:

To trend DAQ-CRC errors from h1edc which started this weekend, these channels were added to h1edc (H1EPICS_DAQ.ini file change). Number of channels increased by two from 40,086 to 40,088.
