Summary
You should consider different languages and use cases when you're developing logic blocks. This chapter has introduced all of the available programming languages that TIA Portal offers programmers and explained where they can be used. It also provided an overview of what they look like and how they are used.
This chapter should have helped you appreciate the different languages and what they can offer an overall project.
The next chapter will expand on this by providing more detail on the languages mentioned here and how to program them. A basic sand filter cleaning sequence will be programmed in each of the languages (where possible) to demonstrate how to construct a block in the respective language and what issues will be encountered.
