5. Make connections to the cascade compound as described in the next section.



Connecting Inputs and Outputs
The cascade compound is fully functional as loaded. If it is the only compound in your
strategy, the only connections required are the I/O wiring connections to the instrument
terminal block.

Connections to other blocks or compounds in your strategy can be made as required. For
example, if the slave process input is flow, the signal could be totalized by loading a totalizer
compound into your strategy and connecting the result from the slave input function block to
the process variable input of the totalizer compound.
