Device Diagnostic
The 266 PdP FF produces different type of diagnostic information:
• Device Diagnostic
These are the diagnostic information produced by the Resource and Transducer Blocks and refer to the device status/health
• Process Diagnostic
These are the diagnostic information which are seen through process variable status and process alarms such as the HI, HI HI,
LO, LO LO, DV HI and DV LO alarms implemented in various Function blocks.
Scope of this section is to describe the Device Diagnostic to be consumed in the Asset Management Software.
Standard errors
The FF standard parameter defining the device diagnostic conditions is the BLOCK_ERR contained by each block and mapped as
follow:

HMI_VARIABLE_RANGE
The High and Low HMI Scale limits
with the engineering units code
Scaling applied at the PRTB_PRIMARY_VALUE for displaying purpose only
and has not effect on the PRTB_PRIMARY_VALUE in input at the AI blocks.
HMI_VARIABLE_CUSTOM_UNIT
Textual custom unit

HMI_BARGRAPH
HMI_SEQUENCE
Sequence/Autoscrolling OFF
Sequence/Autoscrolling ON
In order to recognize the displayed variable among all those in this list, it appears a three character string in the left
side of the value when two lines mode is selected and below the value when One Line Mode is selected. The strings
for any variables are:
0:
P-dP (default) ‘PV’
Sensor Temp ‘ST’
Static Pressure ‘SP’
HMI Variable ‘HMI’
PV Trim Value ‘TPV’
Static Pressure Trim Value ‘TSP’
Scaled PV ‘LIN’
OUT PID ‘PID’
OUT AR ‘AR’
OUT IS ‘IS’
OUT IT ‘IT’
OUT CS ‘CS’
