Corrective Action
Set target mode to something other than OOS
BLOCK_ERR [6] will show the configuration error bit set.
The following are parameters that must be set before the
block is allowed out of OOS:
D CHANNEL [15] must be set to a valid value and cannot
be left at initial value of 0.
D XD_SCALE [10]. UNITS_INDEX must match the units in
the transducer block channel value.
D L_TYPE [16] must be set to Direct, Indirect, or Indirect
Square Root and cannot be left at an initial value of 0.
The actual mode of the Resource block is OOS. See
Resource Block Diagnostics for corrective action.
Block is not scheduled and therefore cannot execute to go
to Target Mode. Schedule the block to execute.
FEATURES_SEL [18] in the resource block does not have
Alerts enabled. Enable the Reports Supported bit.
LIM_NOTIFY [32] in the resource block is not high enough.
Set equal to MAX_NOTIFY [31], also in the resource block.
STATUS_OPTS [14] has Propagate Fault Forward bit set.
This should be cleared to cause an alarm to occur.
L_TYPE [16] must be set to Direct, Indirect, or Indirect
Square Root and cannot be left at an initial value of 0.
Scaling parameters are set incorrectly:
D XD_SCALE.EU0 and EU100 should match that of the
transducer block channel value.
D OUT_SCALE.EU0 and EU100 are not set properly.
Limit values are outside the OUT_SCALE.EU0 and
OUT_SCALE.EU100 values. Change OUT_SCALE [11] or
set values within range.
