Alarm: In a control system, the alarm refers to the messages which help to point out the fault conditions occurred in the system. An alarm summary will contain a list of time stamped active alarms in the system. Human Machine Interface (HMI): HMI is a hard-wired panel board which helps to operate the control process using a simple touch-screen on the required control icon. HMI eliminates the use of hard-wired components like switches, relays, push buttons, and many such. During control operations, HMI enables one to watch the operation results by means of graphs. HMI communicates with Programmable Logic Controller (PLC) and I/O sensors for getting and providing information for users to view. It helps in optimizing an industrial process by digitizing and centralizing data for a viewer.
