Abstract
In one aspect, the invention is a method for communicating with a device such as a programmable logic controller (PLC) or an I/O device. The method includes steps of: interconnecting the device to a personal computer (PC) running a web browser; and running an application on the PC that launches the web browser to an initial page and uploads a web browser applet or active x object from the device to the PC via the interconnection. The above-described embodiment combines PLC and/or I/O communications with the Internet's wide reach and ability to supply information, and does so with the 'look and feel' of a PC-Internet interface without adding significantly to the overhead burden of these small devices.
