Control System Code Structure

To achieve goals of modular, self-sufficient, independent phase blocks, the structure of the control system code for each phase block and for entire processes must be consistent. This is necessary so that phase blocks can easily be placed in other processes with little reprogramming. Use the following guidelines when structuring individual phase blocks and completing process programs.

Program sequencing can be disrupted if the processing capabilities of your plant are altered after initial program structuring. However, if all additions are structured in a similar manner and added to the end of the code, the complete program consists of smaller programs, all with the same consistent structure.
