In this video, Zahraa Khalil explains the definition of Human Machine Interface, or HMI, the functions the HMI provides, and where it is used within the control system.
- [Instructor] An HMI is a software application…that presents information to the users…about the state of the process…and also to accept the user and control instructions.…HMI provides a graphical representation…of the control system process…and provides real time data acquisition.…It monitors data and make it available to users,…as well as provides an interface…for inputs from the users.…One of the advantages that HMI provides…is that they provide an interface between the user…and the machine within the factory floor,…a centralized control unit and a local interface…of the process for quick monitoring and adjusting.…
So as the name implies, HMI, human-machine interface…allows humans and machines to interact.…The size of HMI varies.…It depends on the different locations,…as well as the vendors.…Here are some examples of human-machine interfaces…provided by Allen Bradley and Siemens.…This is an example of a built-in HMI interface…used for monitoring a continuous process…for a mixing project.…This HMI takes inputs, the status of the valve…
Learn about the components and networks involved at each level of automation: field level, control level, and management level. Explore the different devices involved, from the programmable logic controllers (PLCs) on the factory floor, to OPC software that give technicians insights into operations. Instructor Zahraa Khalil, an engineer and educator, also provides an overview of SCADA (supervisory control and data acquisition), an industrial control system architecture that enables supervision over large distances and multiple sites.
