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.

Multiple Analog Input Block

The Multiple Analog Input Block allows for up to 8 variables to be published in

one macro cycle. The primary purpose of this block to publish data that is

channeled to it from the Advanced Diagnostic Block.

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.

Mass Flow Transducer Block

The Mass Flow Function Block is an optionally licensed transducer block (H01

option) that will output a fully compensated mass flow value. It accepts

Differential pressure, gage or absolute pressure and temperature inputs and

then uses the flow calculation equation generated by the Engineering

Assistant configuration tool to derive the output. The user can enter a fixed

temperature if a temperature device is not available.
