Improving communication quality
Low Power Consumption, Outstanding Robustness
In addition to the Ethernet port, the FCN-RTU is equipped
STARDOM FCN-RTU with four serial ports allowing to build a reliable network
Low Power Autonomous Controller with the main line and backup lines. Thus stable data
transmitting and receiving to and from the Supervisory
Control And Data Acquisition (SCADA) system is provided.
Complying with the Distributed Network Protocol (DNP3),
the FCN-RTU can send only changed data among buffered
data, thus reducing communication costs and improving
In response to emerging countries’ growing demand for communication quality.
