MOXA Ethernet remote I/O with 2-port Ethernet switch, 4 AOs

Daisy-chained Ethernet I/O Connection
A new daisy-chained Ethernet I/O concept is now available. The ioLogik E1241 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 E1241 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.
