Block_Err Possible Reasons OUT Status
Block Configuration error
– CHANNEL = 0 (uninitialized)
– L_TYPE = 0 (uninitialized)
– XD_SCALE != OUT_SCALE and LIN_TYPE = DIRECT
– CHANNEL = 4 (Scaled_PV), and L_TYPE = Indirect Square Root
– CHANNEL = 4 (Scaled_PV), and XD_SCALE different by 0/100 %
When the Block Configuration Error is set, the AI cannot exit from
OOS and the OOS condition is also set in the AI Block Error.
In this case the OUT_STATUS = BAD-OOS overrides the BAD-
Configuration Error
Simulate active
The Simulation has been set with the HW switch and the SIMU-
LATE_EN/DIS = Active
The OUT_STATUS is produced as result of the normal calculation
within the AI block but starting from a simulated Status instead of
the real TB Status
Input Failure/process
variable has BAD status
The value in input coming from the TB has BAD Status.
IF STATUS_OPTS-Propagate Fault Forward = Set:
– BAD Sensor Fail
– BAD Device Fail
Received in input from the TB are produced also as AI OUT Status.
All the other BAD status are propagated as:
– BAD-not specific.
IF STATUS_OPTS-Propagate Fault Forward = Clear:
All the BAD status are propagated as
– BAD-not specific
Out-of-Service The Actual_Mode is OUT OF SERVICE
The OUT_STATUS is BAD-OOS. In case of concomitance with
other conditions this is the status produced in output because this
is the High priority Status condition
OUT Status
Binary Code Decimal Code Quality Sub-Status Status_Opts Descrition
0000 0000 0 BAD non specific Propagate Fault Forward = Clear The value in input at the AI has BAD status
0000 00xx 1-3 BAD non specific BAD if Limited = Set
The value in input at the AI has status limit set “low
limited” or “high limited” or “constant”
0000 1100 12 BAD Device Failure Propagate Fault Forward = Set The value in input at the AI has BAD-Device Failure status
0001 0000 16 BAD Sensor Failure Propagate Fault Forward = Set The value in input at the AI has BAD-Sensor Failure status
0001 1111 31 BAD Out of Service The AI_MODE_BLK.ACTUAL = OOS
0100 0000 64 UNCERTAIN non specific Propagate Fault Forward = Clear The value in input at the AI has UNCERTAIN status
0100 00xx 65--67 UNCERTAIN non specific UNCERTAIN if Limited = set
The value in input at the AI has status limit set “low
limited” or “high limited” or “constant”. See NOTE A
0100 1000 72 UNCERTAIN Substitute set UNCERTAIN if Man Mode = set The MODE_BLK.ACTUAL of the AI = MAN

IF (OUT > (OUT_SCALE_100% + 10%)) OR (OUT <
(OUT_SCALE_0% - 10%))
In case of reverse range, See NOTE B
IF (OUT < (OUT_SCALE_100% - 10%) OR. (OUT >
(OUT_SCALE_0% + 10%)
1000 0000 128 GOOD_NC ok
The value in input at the AI has GOOD_NC status
1000 0100 132 GOOD_NC Active block alarm ACK_OPTION = set
When an AI BLOCK_ERR condition is set, if the AI goes
in OOS, the OUT status cannot be set to
GOOD_NC.Active block alarm. See NOTE C
1000 1010 138 GOOD_NC Active Advisory Alarm ACK_OPTION = set
The OUT_VALUE is outside the limits (HI_HI, HI, LO,
LO_LO) and the priority of the limits is between 3 and 7
1000 1110 142 GOOD_NC Active Critical Alarm ACK_OPTION = set
The OUT_VALUE is outside the limits (HI_HI, HI, LO,
LO_LO) and the priority of the limits is between 8 and 15
1000 1001 137 GOOD_NC Unack block alarm ACK_OPTION = clear
When an AI BLOCK_ERR condition is set, if the AI goes
in OOS, the OUT status cannot be set to GOOD_NC.
Unack block alarm. See NOTE C below
