Summary

In this chapter, we explored the FBD origins in systems engineering and introduced the basic concepts of IEC FBD programming. We learned how to create FBDs by dragging and dropping elements into a sheet in a routine. We also learned how to wire input and output references to function block pins and identify digital and analog connections and monitor their values online.

In the next chapter, we will introduce another IEC language called Structured Text Programming and its use in the Logix family.
