## ■ Ethernet communication 

- Measured data can be saved in CSV files 

- Equipped with two Ethernet communication ports, 

so devices can be daisy chained without adding a HUB. 

and visualized by **KW Watcher.** 

- Connectable to both **KW Watcher** and Central monitoring system / SCADA at the same time. 

Central monitoring system SCADA 

HUB PC Visualization software, **KW Watcher** can be downloaded for free from our website. * Registry of customer information is required. * For **KW2M-A** , **DLL** or **ELC** is required to use " **KW Watcher** ". Ethernet
