Summary
In conclusion, we have explored common HMI components such as switches, buttons, LEDs, pots, sliders, spinners, and more. We have also learned how to hook up HMI components and how PLC code can manipulate those components. We also explored how simply using commands in the Properties fields can allow us to manipulate the controls without the need for the PLC.
In all, this chapter has served as the basis for future HMI development exploration. This chapter demonstrated how to use basic controls and how to string them together to form a simple, yet functional, HMI.
As I have stated before, HMI development is as much an art as it is a science. The next chapter will be dedicated to the best practice of laying out an HMI so that your operators can effectively use them. For now, I strongly recommend getting used to the controls and the layout of the Properties menu.
