The human-machine interface (HMI) is the window to the equipment’s operations. As remote connectivity and data sharing continue to play larger roles, machine builders capitalize on the HMI’s digital capabilities. This select panel of experts discusses where HMI software is leading operator interface, as well as the equipment it puts a face on.
What HMI-software technologies are being used to connect edge devices and machines to the operators, supervisors and managers in the plant?
Once, one gets more sophisticated, a deterministic method of communication would be a wise choice, rather than trying to overpower the polling problem with computer horsepower. Today's databased HMIs can be augmented with such deterministic communication.

In disconnected or hard-to-service areas, customers can now collect data and analyze it locally from the in-rack module. With the right architecture, that data also can be stored longer term for future analysis. The ability to have real-time access to data at the edge-device level and consolidate it with other process data at the site or enterprise level allows users to perform their jobs efficiently, regardless of role and location.
