Description
Data Type: DS‐68
The high and low scale values, engineering unit
code, and number of decimal places to be used in
displaying the PV parameter and parameters which
have the same scaling as PV.
Data Type: Float
Data Type: Float
Data Type: Unsigned16
Data Type: Integer8
Data Type: 101
Actual position of the device. This can be
characterized or de-characterized depending on
IN_CHANNEL setting.
Data Type: Float
Data Type: Unsigned8
Indicates validity of VALUE.
Data Type: DS‐65
Target SP and status by supervisory host
Data Type: Float
Data Type: Unsigned8
Indicates validity of VALUE.
Data Type: Unsigned16
Defines which transducer parameter provides input
to the AO READBACK parameter.
Data Type: Unsigned16
Defines which transducer parameter receives the
AO output. Select Positioning_Value to control
valve position.
Data Type: Float
Time in seconds from detection of failure of the
actual used setpoint (SP=BAD or RCAS_IN
<>GOOD) to the action of the block if the condition
still exists. A comm timeout changes the status of
the transmitted setpoint to BAD
Data Type: Unsigned8
Defines the reaction of the device if a failure of the
actual used setpoint is still detected after
FSAFE_TIME or if the status of actual used setpoint
is Initiate Fail Safe.
Data Type: Float
Setpoint used if FSAFE_TYPE = 0 and FSAFE is
activated
