1. SYSTEM LOGIN
Users, including the administrator, log in to CENTO through a web interface. The software supports web browsers such as Google Chrome, Microsoft Edge, etc.
To launch the CENTO software web interface, enter the IP address or DNS address of the server on which CENTO software is installed in the address bar of your web browser, for example, http://192.168.80.10 or https://demo.centosoftware.com/. When working with the system directly on the server where the CENTO software is installed, enter http://127.0.0.1 [MT1] in the web browser's address bar.
After entering the address, the user is redirected to the authorization page, which includes fields for username and password input (see Fig. 1.1).

Figure 1.1. Authorization page
To log in to the system, enter a username and password in the appropriate fields and click Login to confirm. If the username and/or password are incorrect, a message appears: User with the entered parameters not found! In this case, verify the entered data or contact the system administrator.
If the login is successful, the web browser displays the CENTO software web interface panel (see Fig. 2.1).

Figure 1.2. Main panel
If necessary, the system administrator can set any other CENTO interface page as the start page for each user role.
The CENTO software provides flexible user access rights configured by the system administrator. By default, all users have permission to view CENTO pages but are restricted from modifying system settings.
To log in as a different user, move the mouse pointer to the drop-down menu in the upper right corner of the interface and select Logout from the list (see Fig. 1.3).

Figure 1.3. System logout
As a result, the user is redirected back to the authorization page (see Fig. 1.1).
When properly configured, functions (pages) that are inaccessible to the user do not appear in the menu and cannot be accessed. However, if the user manually enters a direct link to a restricted page in the browser address bar, a message indicating that access is denied will appear (see Fig. 1.4).

2. USER INTERFACE
2.1. Main menu
The upper part of the user interface has a pinned main menu (see Fig. 2.1), which is used to switch between different pages and sections of the CENTO software web interface, as well as a status bar that displays current events and system time. Below is the working area of the CENTO software web interface, which is different for each software section.

Figure 2.1. Main menu (left side)
The Main menu provides the following main functional sections of CENTO software:

Switching to the start page (can be different for each role)

Selecting a diagram to be displayed

Real-time data, metering data, receipt of metering data presented in tabular form and as interactive charts

Event logs for both the system as a whole and its individual components
