EZAutomation says it offers the first dedicated human machine interface (HMI) with remote Internet control by introducing Webserver/remote control to the EZSeries touch panels.

HMI enables remote control.

This introduction shifts perception of PLC HMIs, since users previously had two choices for remote Internet control:
1) Use a dedicated operating system in a touch panel, which needs less memory and is faster and more reliable, since the microprocessor is used only to display graphics and communicate to PLCs.
2) Use an HMI with a Microsoft Windows CE operating system, which give the panel Internet capability to send emails when alarm conditions occur and serve Web pages for remote view. This can interfere with PLC communications and is inherently less reliable, slower, and uses a lot of memory.
The Web server remote control card from EZAutomation delivers the best attributes of each option, providing dedicated communications to PLCs and a separate Web process for the Internet. Someone with appropriate security clearance, thousands of miles away from the touch panel, can see what the operator sees and operate the machinery. The device includes 4 GB of data storage in Microsoft Excel format. EZAutomation is part of AVG.
