Model 2700 PROFIBUS Block Parameters
Table F-15 AO function block parameters (continued)
Index Parameter Mnemonic Definition
37 IN_CHANNEL Reference to the active
(DD Name: AO IN Channel) Transducer Block and its
parameter that provides the
actual position of the final
control element.
38 OUT_CHANNEL Reference to the active
(DD Name: AO OUT Channel) Transducer Block and its
parameter that provides the
position value for the final
control element.
39 FSAFE_TIME Time in seconds from
(DD Name: AO Fail Safe Time) detection of failure of the
actual used set point (SP =
BAD or
RCAS_IN <> GOOD) to the
action of the block if the
condition still exists.
40 FSAFE_TYPE Defines reaction of the
(DD Name: AO Fail Safe Type) device, if a failure of the
actual used set point is still
detected after FSAFE_TIME
or if the status of actual used
set point is Initiate Fail
Safe.
41 FSAFE_VALUE Set point used if
(DD Name: AO Fail Safe FSAFE_TYPE = 1 and
Value) FSAFE is activated.

47 POS_D The current position of the
(DD Name: AO POS_D) valve
48 RESERVED
49 CHECK_BACK Detailed information of the
(DD Name: AO Check Back) device, bitwise coded. More
than one message
possible at once.
50 CHECK_BACK_MASK Definition of supported
(DD Name: AO Check Back CHECK_BACK information
Mask) bits.
51 SIMULATE For commissioning and
(DD Name: AO Simulate) maintenance reasons, it is
possible to simulate the
READBACK by defining the
value and the status.
52 INCREASE_CLOSE Direction of positioner in
(DD Name: AO Increase mode Rcas and Auto
Close)
53 OUT This parameter is the process
(DD Name: AO Out) variable of the AO Block in
engineering units in AUTO
mode and is the value
specified by the operator in
Manual mode.
54 OUT_SCALE Scale of the Process
(DD Name: AO Out Scale) Variable.

Substitute Value
1: use last valid set point

UNCERTA–N – Last
usable Value
or B–D – No
communication, no LUV
2: actuator goes to
