4 eSite Web

4.1 Overview

The eSite Web interface is accessed on site via a laptop or a smartphone using Wifi or LAN cable, see Site Commissioning on how to connect to Wifi. The interface provides the user with an overview of the status of the eSite Modular system and active alarms. It also offers possibilities to configure the system, update controller softwares and download backup data.

From the front page, which displays an overview of the most important system information, tabs with more detailed information about various system parts are accessed. An example of the view on the eSite Web front page is shown in Figure 4.1. Click the labels on the menu bar to access the detailed information sections and to configure the system.

Commissioning

This is a forward link to the Site Commissioning guide. During Site Commissioning, settings for the eSite Modular system are finalized upon installation. The Site Commissioning makes sure that the eSite Modular system is set up correctly and operates as intended. Moreover, the Site Commissioning guide is where all RE/RSE/SE Converter Units are registered and unregistered. Detection of a connected, unregistered unit automatically starts the Site Commissioning guide. To unregister a registered Converter Unit, please enter the Site Commissioning guide from this menu
