EcoStruxure Web Services (EWS)

EcoStruxure Web Services (EWS) for Power Operation shares real-time, historical, and alarm data with EcoStruxure™ Building Operations (EBO) and historical data with Power Monitoring Expert (PME). Do not confuse this feature with the EWS Server that was released as a part of PowerSCADA Expert/Vijeo Citect version 7.40 (which is for tag level process data).

EWS uses web-based HTTP protocol to transfer data. It enables two-way data transfers, which allows the acknowledgment of alarms from EBO. To include this new EWS implementation in your installation, select the EWS Server check box during installation.

EWS is set up and configured using the Application Configuration Utility.
