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

A. CAS_IN = The remote setpoint value from another function block
B. BKCAL_OUT = 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.
C. OUT = The block output value and status
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 242 and “Analog Output block” on page 126.
