Summary

This chapter has explored essential areas of HMI navigation and alarming. These aspects of HMI development are key to providing information to the end user and building a robust and easy-to-use system. Being able to create easy-to-use navigation systems and clear alarming systems can set a project apart from others, ensuring that end users have an easy experience when the overall system is in use.

Using PLC-driven alarming via the supervision tags can help reduce the amount of work required in the HMI by allowing the PLC to interact directly with the HMI's alarm control. The utilization of PLC-driven alarming ensures that function blocks will raise the same alarms no matter what project they are used in (subject to ProDiag supervisions being available), which can have large time-saving benefits as well as standardization.

Supervision tags use the ProDiag system that requires an additional license after the configuration of 25 supervisions. The license can be set...
