Table C-7 Diagnostics Object (0x66) – Instance 1
Attrib
ID Name Data type Service Mem Description Comments
1 Fault behavior USINT Set NV Specifies the behavior of
the process variables
when the device is in a
fault state
• 0 = Upscale
• 1 = Downscale
•2 = Zero
•3 = NAN
• 4 = Flow goes to zero
•5 = None
2 Fault timeout USINT Set NV The amount of time after a
fault ocurrs before the
fault behavior (Attribute 1)
is implemented
Unit = seconds
3 Slug time REAL Set NV The amount of time the
density is outside the slug
low limit and slug high
limit before a slug flow
condition is declared
Unit = seconds
4 Slug low limit REAL Set NV The lower limit of a slug
flow condition
Unit = g/cm
3
5 Slug high limit REAL Set NV The upper limit of a slug
flow condition
Unit = g/cm
3
6 Discrete event
index
USINT Set V The index of the discrete
event that is being
configured. There are 5
discrete events with the
index starting at 0.
0, 1, 2, 3, 4
7 Discrete event
type
USINT Set NV The type of the selected
discrete event
• 0 = Greater than
Setpoint A
• 1 = Less than
Setpoint A
• 2 = In Range
(A=<x<=B)
• 3 = Out of Range
(A>=x or B<=x)
8 Discrete event
Setpoint A
REAL Set NV Setpoint A of the selected
discrete event
9 Discrete event
Setpoint B
REAL Set NV Setpoint B of the selected
discrete event
10 Discrete event
process variable
USINT Set NV The process variable on
which the selected
discrete event is defined
See Table C-15 for
process variable codes.
All codes are valid
except for 52 (Input
voltage).
11 Discrete event
status
USINT Get V Each bit contains the
status of the
corresponding discrete
event:
• 0 = Inactive
• 1 = Active
• 0x01 = Event 0
• 0x02 = Event 1
• 0x04 = Event 2
• 0x08 = Event 3
• 0x10 = Event 4
