You can't actually detect that, all you really know is that the PV is or
is not connected, which might be for many possible reasons.
"fail to read PV"
Your record will automatically be put into LINK_ALARM state with an
INVALID severity if there was a problem with the link communications
mechanisms.
"PV in alarm".
If the link has an MS flag, it will cause your record to go into a
LINK_ALARM with the severity copied from the link target. You might
also want to look at the MSS and MSI flags which can change that
behaviour slightly; they were added in 3.14.11.
