In summary, this chapter has been a crash course on HMI alarms. We have covered the HMI and PLC side, as well as the setup of the alarms. We have also learned how to acknowledge alarms and more. By this point, you should know the basics of alarm systems. Overall, you will need to understand this chapter to be an automation programmer, so please ensure that you understand the material. In all, you should have a good grasp of advanced PLC programming in general at this point. This means we can move on to our final project of the book, creating an industrial oven.
