The controller provides a command that returns the progress of an acquisition, since they can be quite long.  I have created a PV to query the progress of the acquisition, querying every 0.2 seconds.  I only want to scan when an acquisition is in progress.  I assume I would appropriately set the DISV and DISA fields of the progress PV.  However, I am lost at how I would set these variables from the acquisition code.  Is there an example or description of the bindings?

You might be able to point the SDIS link at the Acquire record.  Use the
CP link modifier.  The value read from SDIS is stored in DISA.  So
setting DISV==0 should disable the scan when Acquire==0.
