Daisy-chained Ethernet I/O Connection
A new daisy-chained Ethernet I/O concept is now available. The
ioLogik E1212 industrial Ethernet remote I/O has two embedded Ethernet
switch ports that allow information to flow to another local Ethernet
device or connect to the next ioLogik in the daisy-chain.
Applications such as factory automation, security and surveillance
systems, and tunnel monitoring, can make use of daisy-chained Ethernet
for building multi-drop I/O networks over standard Ethernet cables. Many
industrial automation users are familiar with the multi-drop
configuration typically used in fieldbus applications. The daisy-chain
function on the Ethernet remote I/O ioLogik E1212 not only increases the
connection between machines and panels, but also lowers the cost of
buying separate Ethernet switches, and at the same time reduces labor
fees and cabling by a large percentage. For example, if a production
facility contains 700 stations (20 points per station), the wiring cost
reduction can reach 15% of the total implementation cost.
Saving Time and Wiring Costs with Peer-to-Peer Communications
In remote automation applications, the control room and sensors are
often far removed, making wiring over long distances a constant
challenge. With peer-to-peer networking, users may now map a pair of
ioLogik E1200 series modules so that input values will be directly
transferred to output channels, greatly simplifying the wiring process
and reducing wiring costs.
