6 HMI
6.1 Introduction
The local HMI features an integrated 7 in. colour LCD panel with resistive touch screen and
embedded webserver. The remote HMI is via a wireless comms option (or direct USB
connection) to a web browser. The latter being the preferred means of interaction with the
product since it offers the convenience of accessing the product from anywhere using a full
screen web browser. The remote HMI is optimised for Chrome, but has also been tested in
Chrome, Firefox and Internet Explorer. The local HMI allows operators to interact directly
with the product onsite without additional equipment. However, the local HMI facility is
intended as an alternative or secondary access method in situations where network
connectivity is unavailable.
To prevent exposure of the internal equipment to extreme weather or other
adverse environmental conditions, ensure additional cover is in place prior to
opening the door.
The LCD panel is in the Hub module and is visible when the door is open as shown in Figure
6-1.

The LCD and web server are powered on by default as soon as power is supplied to the
product. Access to the HMI can be gained locally via the resistive touch screen (using a
finger or stylus) or remotely through the Web from any computer. Both HMI experiences
are comparable with a similar look and feel.
