Blue Fusion programmable automation controllers use patented CTC technology to serve up interactive HMI projects as web pages to the world wide web from a server embedded in the controller. These HMI projects display parameters for the I/O, motion and other devices that the Blue Fusion controls. Process parameters can be displayed and edited by calling up the web page via a standard browser.¹ Security strategies may be invoked to ensure only authorized access.

The HMI projects are created on a PC using CT HMI Builder, CTC’s graphical development software. Once the project has been created, CT HMI Builder converts the project to a CT webHMI project and exports it directly to the server on the Blue Fusion controller.

¹ Because the web pages are Java-based, Java Virtual Machine (JVM) must be installed on the client accessing the web pages. JVM is a widely accepted and installed application that is available as a free download from Oracle.
