6.4 Ladder Logic Implementation
The sample ladder logic performs tasks that are covered in the Ladder Logic
sections of this manual. The most important task is to continuously write meter
process input variables from the processor to the module, and read calculation
results from the module to the processor.
Refer to the Ladder Logic sections for instructions on how to transfer the meter
process variables from the processor to the module. Ladder logic is required to
move the process variables to the correct data file or controller tag in the
processor.
The Meter Monitor window (Process Inputs field) displays the values that are
transferred from the processor.
