Additional manufacturer-specific detailed device information, coded bit-wise
encoded which enables several simultaneous messages, see also Chapter 9.
A: Dynamic messages; they are automatically reset by readout.
R: Static messages; they are retained, as long as the event is imminent in the field device.
0: No message
1: Message active
If the reference variable exceeds the entered limit, the valve moves in the end position,
corresponding to 100 % of the reference variable. Hysteresis 1%.
When the value is 125 %, the function is deactivated.
99 %
Caution: Since the actuator will automatically be filled with air or vented when this
function is executed, the control valve moves in its absolute end positions.
Constraints specified in the function "travel range" or "travel limit" do not apply here.
This function must be deactivated if unacceptably high positioning forces result from
the complete filling/venting action.
If the reference variable falls below the entered limit, the valve moves in the end
position, corresponding to 0 % of the reference variable. Hysteresis 1%.
When the value is −2.5 %, the function is deactivated.
1 %
Caution: Since the actuator will automatically be filled with air or vented when this
function is executed, the control valve moves in its absolute end positions.
Constraints specified in the function "travel range" or "travel limit" do not apply here.
This function must be deactivated if unacceptably high positioning forces result from

Defines reaction when communication failure or device start-up is recognized.
0 = Adjust to fail-safe value
1 = Adjust to/save last valid set point
2 = Move to fail-safe position determined by spring action
1
Fail-safe position of the actuator in the event of air/power failure or start-up.
Read-only value, automatically determined during the initialization process
0 = Not initialized
1 = Opening in direction of the 100 % position
2 = Closing in direction of the 0 % position
3 = None/saving (position is retained)
If the DP watchdog detects a communication failure, the fail-safe action is triggered
after the fail-safe time has elapsed.
