Project Introduction:
A network infrastructure is the heart of any communications system, and includes all of the routers, switches, wireless access points, access methods and protocols needed to operate a modern enterprise. The Metro system in Brazil was looking to upgrade their existing network, and turned to Advantech for the necessary products and know-how. Their main central control center needed a system to monitor and control the communication quality, and required products compatible with their digital analyzers.
System Requirements:
Because the infrastructure of the information layer is Ethernet-based, the digital analyzer must be equipped with an RS-485 to Ethernet device server. The central control center needs to read data from the analyzers for management through Ethernet. In order to ensure the system performs reliability, the communication can’t be interrupted, so redundant communications are required.
The Metro system itself has many high voltage wires for the trains, so there is a lot of interference. Moreover, the communications have to travel very long distances, which creates installation, maintenance and operation issues. To meet these demands the system must be designed with advanced protection and remote configuration capabilities.

System Description:
EKI-1522's has two RS-485 ports, providing redundancy for the system. Through RS-485, the digital analyzer is connected to EKI-1522 at each remote site, while a PC is connected to another EKI-1522 in the main control room to achieve remote configuration capabilities. The EKI-1522 is also designed with two 10/100Mbps ports for LAN redundancy.
Conclusion:
The functionality, quality, reliability and excellent design of EKI-1522 made it a great fit for this project, helping create a reliable communications infrastructure.
