Integration of HMI with PC and PLC environments gets tighter

Keith Hogan, principal platform lead, Rockwell Automation: Rockwell Automation has always prioritized supporting customers throughout their project lifecycle and beyond. We're about to add a new human-machine-interface (HMI) platform to our portfolio: FactoryTalk Optix, a cloud-enabled HMI platform that allows design, test and deployment of applications using a locally installed design environment or directly from a web browser, connecting through our cloud-based FactoryTalk Hub. This modular platform delivers new options for design, deployment and graphics, with extensibility options that make it flexible enough for any application.

It can be deployed on industrial PCs or, starting in 2023, on a new set of OptixPanel HMI terminals. FactoryTalk Optix is an addition to our visualization-platform set and does not replace any existing Rockwell Automation product. It’s a great option for new applications requiring greater flexibility.

What have been the biggest improvements to operator-interface technology in the past five years?

Keith Hogan, principal platform lead, Rockwell Automation: There are several, but one of the biggest is the melding of the hardware-based HMI terminal space with the open PC space. Customers can now get a PC-like user experience on a hardware terminal at a lower price point and simpler device management. For example, users can leverage domain-based security rather than isolated security on a single HMI terminal.

Another is tight integration between the real-time programmable-logic-controller (PLC) environment and the HMI environment, which enables users to implement functions where they make the most sense. For example, implementing alarming in the controller, as opposed to the HMI system, saves time and enables better alarm management.

Lastly, content management and presentation to operators on thin-client hardware has also revolutionized maintenance, created a more secure environment and reduced downtime. Content such as HMI, computerized maintenance management system (CMMS), video feeds or controller programming software is hosted on a centralized server rather than a PC on the plant floor. In the event of thin-client failure, the device is easily replaced and content delivered almost immediately, drastically reducing time spent installing and configuring software on a PC.
