Detailed Setup—DO Function Block
Description
Data Type: Bit String
0=Disable
1=Enable
Allows you to select the type of tracking and the
output value when a fault condition occurs.
Supported I/O options for the DO function block are
SP Tracks PV in Man, SP Tracks PV in LO, SP Tracks
Retained Target in Man or LO, Fault State to Value,
Use Fault state on Restart, Target to Man if Fault
State Activated, and Use PV for BKCAL_OUT.
Data Type: Bit String
0=Disable
1=Enable
Options the user may select for the block processing
of status.
Data Type: DS‐66
0=closed, 1=open, 5, 10, 15, 30...etc. are position in
5% increments.
Data Type: DS‐66
The remote set point value from another block.
Data Type: Unsigned16
Defines which transducer parameter receives the
DO output. Select Setpoint (D) to control valve
position.
Data Type: Float
Time from detection of a fault in the remote set
point to the Fault State output action.
Date Type: Unsigned8
Preset discrete SP_D value to use if I/O_OPTS Fault
State to Value is set.
Data Type: DS‐66
The value and status required by the BKCAL_IN_D
input of another block for output tracking
Date Type: DS‐66
Target set point and status provided by a
supervisory host to a discrete control or output
block.
