These devices can serve Web pages over an Ethernet LAN or over the Internet, making it possible to monitor and control a process through a Web browser within the facility or remotely. Web pages are easily customized and offer password protected access. The iSeries controller can send e-mail alerts or status updates. This is accomplished without a computer. The iSeries device (meter or controller) connects directly to the Ethernet network—not to the serial port of a computer—functioning as a “server” and “master” to “slave” instruments connected through serial communications. Prices start at $150.
