Dual-port Ethernet HMI Systems

As HMI system functionality continues its meteoric growth the technology is positioning itself in the strategic role of information-bridge between factory network layers.  Separation of network layers brings many benefits not least security.  Upper layer systems, for example ERP, CRM and MES etc. often introduce risk attendant with connecting to the outside world via Internet.  Having the commercial, supervisory manufacturing and control systems on the same network means the controllers are vulnerable to attack.

The new MT8073iE & MT8092XE deliver that all important separation with the provision of Dual Ethernet ports.  Network independence is maintained through the connection of the commercial system layer or remote connection such as EasyAccess 2.0 on one port and the control system layer on the second; with the HMI performing a robust data exchange mechanism between the two networks.  The resulting network topology not only separates commercial and control data streams but also reduces network congestion, minimises interference and greatly improves network reliability; with an overarching and seriously positive impact on system security. 

The 7.0” MT8073iE is equipped with Cortex A8 600MHz CPU, 128MB Flash, and 128MB RAM whilst the 9.7”MT8092XE is equipped with Cortex A8 1GHz CPU, 512MB Flash, 256MB RAM and a high-resolution (1024 x 768 pixels) LCD.  An EasyAccess 2.0 license is included with both units therefore absolving the need to use an activation card to activate EasyAccess 2.0 service.
