UNUSED
29 / 13
Unused parameter.
RCAS_IN
30 / 14
Target set point in units of PV_SCALE and status provided by a supervisory host to the
analog control or output block in mode RCas.
UNUSED
31 / 15
Unused parameter.
UNUSED
32 / 16

UNUSED
36 / 20
Unused parameter.
IN_CHANNEL
37 / 21
Reference to the active Transducer Block and its parameter that provides the actual
position of the final control element.
OUT_CHANNEL
Reference to the active Transducer Block and its parameter that provides the position
38 / 22
value for the final control element.
0x014E: TB1.DISPLAY_VALUE
FSAFE_TIME
39 / 23 Time in seconds from 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. Note: A
communication time out changes the status of the transmitted set point to BAD.
FSAFE_TYPE
Defines the reaction of the 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.
In mode FSafe Value, the value of parameter FSAFE_VALUE is used as the set point
value and the status of OUT is set to UNCERTAIN – Substitute Value.
In mode Use Last Valid Set Point, the last value of SP with status GOOD is used and the
40 / 24 status of OUT is set to UNCERTAIN – Last usable Value or BAD – No communication, no
LUV.
In mode Actuator Action, the actuator goes to fail-safe position defined by the parameter
ACTUATOR_ACTION (useful for actuators with spring return only). The status of OUT is
set to BAD – non-specific.
0: Fsafe Value
1: Last Stored
2: Out Status Bad
FSAFE_VALUE
41 / 25
Set point used if FSAFE_TYPE = 1 and FSAFE is activated.
UNUSED
42 / 26
Unused parameter.
RCAS_OUT
43 / 27 Function Block set point in units of PV_SCALE and status. Provided to a supervisory
Host for monitoring / back calculation and to allow action to be taken under limited
conditions or mode change.
