Attrib
ID	Name	Data type	Service	Mem	Description	Comments
1	Fault behavior	USINT	Set	NV	Specifies the behavior of	• 0 = Upscale
					the process variables	• 1 = Downscale
					when the device is in a	• 2 = Zero
					fault state	• 3 = NAN
						• 4 = Flow goes to zero
						• 5 = None
2	Fault timeout	USINT	Set	NV	The amount of time after a	Unit = seconds
					fault ocurrs before the
					fault behavior (Attribute 1)
					is implemented
3	Slug time	REAL	Set	NV	The amount of time the	Unit = seconds
					density is outside the slug
					low limit and slug high
					limit before a slug flow
					condition is declared
4	Slug low limit	REAL	Set	NV	The lower limit of a slug	Unit = g/cm3
					flow condition
5	Slug high limit	REAL	Set	NV	The upper limit of a slug	Unit = g/cm3
					flow condition
6	Discrete event	USINT	Set	V	The index of the discrete	0, 1, 2, 3, 4
	index				event that is being
					configured. There are 5
					discrete events with the
					index starting at 0.
7	Discrete event	USINT	Set	NV	The type of the selected	• 0 = Greater than
	type				discrete event	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	REAL	Set	NV	Setpoint A of the selected
	Setpoint A				discrete event
9	Discrete event	REAL	Set	NV	Setpoint B of the selected
	Setpoint B				discrete event
10	Discrete event	USINT	Set	NV	The process variable on	See Table C-15for
	process variable				which the selected	process variable codes.
					discrete event is defined	All codes are valid
						except for 52 (Input
						voltage).
11	Discrete event	USINT	Get	V	Each bit contains the	• 0x01 = Event 0
	status				status of the	• 0x02 = Event 1
					corresponding discrete	• 0x04 = Event 2
					event:	• 0x08 = Event 3
					• 0 = Inactive	• 0x10 = Event 4
