 Industrial Automation Interface

Columbia Weather Systems’ Weather MicroServer offers DNP3 ethernet communication to interface CWS weather stations with process automation systems used primarily in utilities such as electric and water companies.

Distributed Network Protocol was developed for communications between various types of data acquisition and control equipment. It plays a crucial role in SCADA systems where it is used by SCADA Master Stations (aka Control Centers), Remote Terminal Units (RTUs), and Intelligent Electronic Devices (IEDs).1

For network setup, please refer to the System Diagram below. The Weather MicroServer offers additional features including additional sensors and monitoring options such as the Weather Display. For additional information go to: Weather MicroServer
