Figure 4-12. Analog-Output
Block
4-36
Signal Characterizer Block
The Signal Characterizer (SGCR) Function Block characterizes or
approximates any function that defines an input/output relationship. The
function is defined by configuring as many as twenty X,Y coordinates. The
block interpolates an output value for a given input value using the curve
defined by the configured coordinates. Two separate analog input signals can
be processed simultaneously to give two corresponding separate output
values using the same defined curve.
Integrator Block
The Integrator (INT) Function Block integrates one or two variables over time.
This block will accept up to two inputs, has six options how to totalize the
inputs, and two trip outputs. The block compares the integrated or
accumulated value to pre-trip and trip limits and generates discrete output
signals when the limits are reached.
Control Selector Block
The Control Selector Function Block selects one of two or three inputs to be
the output. The inputs are normally connected to the outputs of PID or other
function blocks. One of the inputs would be considered Normal and the other
two overrides.
Output Splitter Block
The Output Splitter Function Block provides the capability to drive two control
outputs from a single input. It takes the output of one PID or other control
block to control two valves or other actuators.
Analog Output Block
CAS_IN
AO
CAS_IN
BKCAL_OUT
OUT
The Analog Output Function Block accepts an output value from a field device
and assigns it to a specified I/O channel. For further information refer to
"Analog Output Block" on page C-9 and "Analog Output Block" on page 4-48.
BKCAL_OUT
OUT
=The remote setpoint value from another function block
=The value and status required by the BKCAL_IN input of
another block to prevent reset windup and to provide
bumpless transfer to closed loop control.
=The block output and status.
