Program Plan Intro

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.
