Project Introduction

Wind farm networks employ SCADA systems to collect data from wind turbines. A PLC (Programmable Logic Controller) is used for data acquisition and the data is sent via an Ethernet switch. A notable wind turbine manufacturer from Spain was looking for embedded computers to control and exchange data from the PLC to the Ethernet switch to improve data communications and management.


System Requirements
  • An on/off switch system to control the data from the PLC (lock, bypass, or pass to the Ethernet switch)
  • Dual LAN ports for configuring and transmitting data from PLCs to Ethernet switches
  • Built-in DI/DO to control the on/off switch system, detection system and alarm system
  • Front-end data computing and storage


Moxa Solution

System Solution

Initially, the wind turbine in this case study was without embedded computers so the data passed from the PLC to the Ethernet switch without filtering or managing any front-end data.

By using Moxa's IA260 embedded computers, our client can decide whether to lock, pass, or bypass the data from the PLC to the Ethernet switch, as well as compute, store, and filter front-end data to improve data communications and management.

Moxa's IA260 features 8+8 DI/DOs to control the on/off switch as well as intrusion detection and alarm light systems. In addition, some DI/DOs can be reserved for future use. The dual LAN ports (one fixed IP and one configurable port) allow data to be transmitted from the PLC to the Ethernet switch. The switch will then deliver data to the SCADA system. In addition, a CompactFlash slot and extra serial interfaces (4 serial ports) are available for future storage expansion and use.
