Daisy-chained Ethernet I/O Connection
A new daisy-chained Ethernet I/O concept is now available. The ioLogik E1214
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 E1214 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.
User-definable Modbus/TCP Addressing for Painless
Upgrading of Existing Systems
For Modbus devices that are controlled and detected by fixed addresses, users
need to spend a vast amount of time researching and verifying the
configurations. Users need to locate each device’s networking details like I/O
channels, or vendor-defined addresses to enable the initial or start address of
a SCADA system or PLC. The ioLogik E1200, with user-definable Modbus/TCP
addressing, offers greater flexibility, and setup is easy. Instead of worrying
about individual devices, users simply configure the function and address map to
fit their needs.
