In this section, we’ll look at basic control scenarios and how to find a solution that fits the control requirements.
We won’t focus on any modular, repeatable or structured control patterns at this stage as people getting started with basics tend to focus on using Tags and general instructions to provide solutions.
The most basic implementations of PLC coding are retrieving digital signals from the IO (Input/output) hardware and then utilizing it to control processes and outputs.
This section focuses on exploring these fundamentals that are used as core principles for wider control, ranging from basic switch management through to alarm management and control.
