Valve Safe State
See Note: Valve Safe
State below
Configures the behavior of the valve when the device
is in Safe Mode.
[0x32-1-21]
Valve Override
3
See Note: Valve
Override below
Overrides the controller by commanding the valve to
one of the selectable values in the table below.

4.1.9.1. Valve Safe State Values
The following table outlines valid safe states for the valve. This table applies
for normally closed and normally open valves.
Table 4-7 Valve Safe State Values
Value State
Description
0
Closed
The valve will be driven closed and the valve position will
be 0% or 0 Counts
1
Open
The valve will be driven open and the valve position will
be 100% or Full Scale Counts Value
2
Hold Last Value
The valve will be driven to the last updated value just
prior to the entering of the safe state.
3
Use Safe Value
The valve will be driven to the value configured in the
Safe Value attribute of the S-Analog Actuator
1
This parameter is only configurable when the device is in the Idle State (i.e. when the device is not being actively scanned/polled).
2
This parameter will automatically be set based upon the inferred data type of the selected Assembly used for I/O (i.e. if an Assembly is
selected that reports valve position, and the inferred data type of the assembly is INT, then this attribute will be automatically set to INT once
I/O data exchange begins)
3
This Override action only occurs when the device is in the Executing State.
