ideal technology for cell phones and PDAs.
OPC is the leading protocol for data communications
between industrial hardware devices and Windows software. The

capabilities, which also include ASP-based reports and live data
updates using Java applets.
Besides AJAX, the latest version of the OPC DataHub shows

server bridges with a few mouse clicks. There are more options
for connecting to OPC servers. It is now easier to write data
