Same as that for the AI block.
Measured value; Non-dimensional value
that is converted from the input (IN) value
based on the PV_SCALE values and
filtered.
Setpoint
Output value.
Scale conversion value for the input (IN)
value.
Scale values used for converting the control
output (OUT) value to actual amount.
Same as that for the AI block.
Defines settings for control action.
See Subsection A5.13.1 for details.
See Subsection A5.15.3 for details.
Measurement input
Time constant (in seconds) of the first-order
lag filter applied to measurement input
Switch whether to set the BYPASS
operation; set ON to bypass the control
operation.
Cascade setpoint
Rate-of-decrease limit for setpoint (SP)
Rate-of-increase limit for setpoint (SP)
Upper limit for setpoint (SP)
Lower limit for setpoint (SP)
Proportional gain
Integration time (seconds)
Unused
Derivative time (seconds)
Read-back of control output
Upper limit for control output (OUT)
Lower limit for control output (OUT)
Hysteresis for release from a limit for OUT.
status
Read-back value to be sent to the BKCAL_
IN in the high-level block
