ioLogik E1200 Series User's Manual

Overview

The ioLogik E1200 series is a stand-alone, remote Ethernet I/O which has two embedded switch
ports. They are designed for remote data acquisition and monitoring of attached sensors,
transmitters, transducers, and valves over a network.

Star Topology of Ethernet Automation

Ethernet requires infrastructure equipment such as switches for connecting a variety of different
devices to the network. This is unlike most field-bus automation networks that use a daisy-chain
topology, which presents a bit of a problem for Ethernet automation applications since when
connecting to Ethernet, meters and gauges must be formed in a "star" configuration. The ioLogik
E1200 series provides an alternative to spending the time and money needed to figure out the best
way to hook up your Ethernet switches. Since each E1200 unit has two built-in Ethernet switches,
the E1200 solution is tailor-made for a daisy-chain type configuration.
