INTRODUCTION
This section lists the function codes used by the controller
module to control the process. (For complete information
about COM function codes, refer to
I-E93-900-20
,
Function
Code Application Manual
).
A variety of control and math functions reside in the module's
firmware. These are known as function codes. These codes,
when assigned to addresses in NVM, become function blocks.
Link these function blocks sequentially to perform the control
strategy. Figure
shows an example of a ratio control loop
configuration
