Plant operators can view alarms provided by the human machine interface to locate any malfunction of equipment and react faster.  Alarms may be preventive, alerting the operator before an emergency level is reached.  Alarms can also be used to track various problems and to optimize manufacturing processes to increase productivity.

Operators can rely on HMI messaging for pages, faxes, etc. when certain events happen. For instance, operators can be alerted automatically when a machine’s fuel level is low and needs to be refilled.

Easily manage and execute recipes using HMI technology. The high-quality graphics of HMI systems provide a realistic view of plant operations, so an operator can control the facility from a central location. This helps with safety as well

Plant managers can easily test devices and equipment using a flexible HMI with simulation.  Testing can be achieved in office without a single piece of equipment.  This helps reduce startup time and improve overall production.

A human machine interface can reduce operation costs because it can replace hundreds of selectors, push buttons, indicator lights, etc. This means the need for additional panels, cables and consoles is also greatly reduced.

HMI improves communications among various types of equipment throughout the facility with the use of remote I/O, Ethernet, serial port, Data Highway Plus, DDE (Dynamic Data Exchange), and other methods.
