Application Requirements
System Solution
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


Initially, the wind turbine in this case study did not have embedded computers so data was passed from the PLC to the Ethernet switch without any filtering or management of the 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, alarm and lighting systems, with extra DI/Dos available 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.
