Configuration/Operation
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
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 79 and “Analog
output block” on page 165 .
