Dual Ethernet Port: Smart Daisy Chain Topology
Moxa’s Smart Dual Ethernet Port Remote I/O Help Cut Cabling Costs and Increase Efficiency
Project Background
One of the world’s leading LED lighting designers has chosen Moxa’s ioLogik E1212 for their Gateway Bridge lighting project in Australia. The city government in charge of the bridge decided to use an Ethernet-based architecture for the bridge’s lighting control system. The total length of the bridge is 1.2 miles, it stands 250 feet off the ground, and the lighting system uses 2500 customized LED strips made up of 90,000 individual LEDs and over 45,000 meters of cable. The challenge for this project was to develop a cost-effective design that satisfied strict cabling layout criteria and was guaranteed to provide long-term performance.
Why Moxa?
Moxa’s ioLogik E1212 Ethernet remote I/O products have a 2-port embedded Ethernet switch with 16 I/O channels, providing users with a very attractive cost-to-performance ratio. Thanks to its two embedded Ethernet switch ports, the ioLogik E1212 gives users the option of creating a daisy-chain Ethernet topology that can be deployed quickly and reduce costs. The simplicity of the daisy-chain architecture makes it easy to wire and maintain, and the cascading connections make it easy to create multi-drop I/O control networks, which are perfect for applications that extend over a distance of 1.2 miles. In addition, the two Ethernet ports can be used to construct a backup link to ensure network redundancy and stability.
With 8 DIs and 8 DIOs, the ioLogik E1212 provides the flexibility needed for this type of application. The ioLogik E1212 is compact, and when used together with Moxa’s V462 embedded computer, it gives users local control capability for managing the bridge’s complex lighting system.
