Track in Manual selection must be true for this to occur
in Manual mode. If the actual mode is OOS or IMan,
the track request is ignored.
If the TRK_VAL replaces the OUT, its status becomes
Locked Out with Limits set to Constant. The actual
mode goes to LO. The status of BKCAL_OUT,
RCAS_OUT and ROUT_OUT goes to Not Invited (NI),
if not already there.
If the status of TRK_IN_D is Bad, its last usable value
will be maintained and acted upon. If the device
restarts, losing the last usable value, it will be set to
false.
If the status of TRK_VAL is Bad, the last usable value
will be used. If there is no last usable value, the
present value of the OUT will be used.
Use the Obey SP limits if Cas or RCas
CONTROL_OPTS to use SP value after limiting in Cas
or RCas mode.
Use the Use PV for BKCAL_OUT CONTROL_OPTS
to the PV value for the BKCAL_OUT value.
