Ethernet XServer lets you add an instant Ethernet port to your M-series PLCs. When connected to your office or home network, it provides a continuously operating TCP/IP gateway to the PLCs to allow for remote programming, monitoring and controling of the PLCs via the LAN or the Internet.

Wireless LAN (802.11a,b or g)

If your premise already has a Wireless LAN infrastructure in place, then you can connect the XServer to your Wireless LAN easily by means of an inexpensive Wireless Ethernet bridge, such as the WET11 made by Linksys. All you need to do is to first set up the WET11 to integrate into your Wi-Fi network, and then just connect a CAT5 cable between the WET11 and the XServer Ethernet port and your XServer (along with your PLCs) will instantly become a member of your Corporate LAN!

The user can easily integrate this control applet into their  PLC program with customized legends of the push buttons and variables without writing a single line of Java code!  This is likely to be fastest way of adding a Web-based HMI to your equipment without learning anything about Java programming!   You can even use a PDA such as Pocket PC or Palm with Java support to use the Applet to control your equipment, as shown in the figure.
