Chapter 6: Creating Standard Control Objects
This chapter explores using function blocks and functions to create standardized control objects.
This approach takes the structured aspect of programmable logic controller (PLC) programming to an additional level, where data and control are brought together to act as a standard method. By utilizing this approach, confidence in the reusability of code is greatly increased, while management and maintenance of code are greatly reduced.
In this chapter, the following topics will be covered:
- Planning standard interfaces
- Creating control data
- Creating HMI data
- Structuring logic
- Considerations that have an impact on usability
Note
This chapter builds on information contained in Chapter 3, Structures and ...
