A8.2.12 ILBD Parameter Lists
All the ILBD parameters belong to the SENSOR Transducer block.
Note: The Write Mode column contains the modes in which each parameter is write enabled.
O/S: Write enabled in O/S mode.
MAN: Write enabled in Man mode and O/S mode.
AUTO: Write enabled in Auto mode, Man mode, and O/S mode.

Explanation
83 2083 DIAG_MODE Stop (0) AUTO Select the function mode for the ILBD.
Stop (0): The blockage detection is stopped.
Calculation (1): The blockage detection is carried out. The alarms
are generated along with the detected result.
Reference (2): The reference values are obtained and the update
values are overwritten. After setting, this mode
changes automatically to Calculation (1)
84 2084 DIAG_PERIOD 180 (s) AUTO Set the data acquisition period for ILBD within the range of 20
to 65535 (s). Writable only when DIAG_MODE is Stop(0). If the
process uctuation values are unsteady, change this value to the
longer to enhance the accuracy of the blockage detection.
85 2085 DIAG_PRI 1 AUTO Set alert (DIAG_H_ALM and DIAG_L_ALM) priority for ILBD.
Writable only when DIAG_MODE is Stop(0).
86 2086 DIAG_ERR 0x0000 The following ILBD results are shown.
A Blocking (bit 2)
Large Fluctuation of Low Side (bit 3)
Large Fluctuation of High Side (bit 4)
Low Side Blocking (bit 5)
High Side Blocking (bit 6)
B Blocking (bit 7)
Invalid Ref BlkF (bit 8)
Invalid Ref fSPh (bit 9)
Invalid Ref fSPl (bit 10)
Invalid Ref fDP (bit 11)
Outside Diagnosis Range (bit 12)
Flg Temp Low Alarm (bit 13)
Flg Temp High Alarm (bit 14)
Bit 15 is used to link the alarm to status of PRIMARY_VALUE,
SECONDARY_VALUE, and TERTIARY_VALUE.
87 2087 DIAG_H_ALM Alerts for high-pressure side are indicated.
A Blocking
B Blocking
Large Fluctuation of High Side
High Side Blocking
Invalid Reference value (BlkF, fSPh, or fDP)
Outside Diagnosis Range
88 2088 DIAG_L_ALM Alerts for low-pressure side blockage are indicated due to the
following factors.
A Blocking
B Blocking
Large Fluctuation of Low Side
Low Side Blocking
Invalid Reference value (BlkF, fSPl, or fDP)
Outside Diagnosis Range
89 2089 DIAG_OPTION 0x08FC AUTO The alarm status linked to an analog alert and LCD display is
selected by DIAG_OPTION in the SENSOR Transducer block.
The alarm selected in DIAG_OPTION is corresponding to bit of
DIAG_ERR.
BIT 15 is used to link the alarm to the status of PRIMARY_VALUE,
SECONDARY_VALUE, and TERTIARY_VALUE.
If set to 1, the signal status becomes “UNCERTAIN: Non Specic
when the ILBD algorithm detects the abnormality.
Writable only when DIAG_MODE is Stop(0).
