Diagnostic
Block_Err Possible Reasons
– CHANNEL = 0 (uninitialized)
– L_TYPE = 0 (uninitialized)
– XD_SCALE != OUT_SCALE and LIN_TYPE = DIRECT
Block Configuration error
– CHANNEL = 4 (Scaled_PV), and L_TYPE = Indirect Square
Root
– CHANNEL = 4 (Scaled_PV), and XD_SCALE different by 0/100 %
The Simulation has been set with the HW switch and the
Simulate active
SIMULATE_EN/DIS = Active
Input Failure/process
The value in input coming from the TB has BAD Status.
variable has BAD status
Out-of-Service The Actual_Mode is OUT OF SERVICE
Description / Range / Selections / Note
Advisory Low Alarm
Critical Low Alarm
These parameters are used by a device
to report more specific details regarding
persistent errors that are reported through
BLOCK_ERR.
Digital Output Value set when the AI_OUT
Value, over-cross the thresholds selected with
the ALARM_SEL_TYPE. The ALARM_HYS enter
in the calculation for setting and clearing the
Digital state in order to avoid continuous
changing whenever the Out Float value is
around to the threshold.
Bit 0 HI_HI_LIM
Bit 1 HI_LIM
Bit 2 LO_LIM
Bit 3 LO_LO_LIM
Channel Not Initialized
Wrong Channel
Channel Unit Mismatch
L_Type Not initialized
Wrong L_Type
Writeable only if MODE_BLK.ACTUAL = MAN
0 – Alarm Diabled
1 – Alarm Enabled
Selection of the AI Limits used as threshold for producing the Digital
output when the OUT Value over-cross the selected limits
(more of one limit can be simultaneously enabled)
OUT Status
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
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
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
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
