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).

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
Reports on data entry into the system (Flexible reports. Power quality reports. Short-circuit currents)
Detailed configuration of CENTO software. Administration and system setup
The upper right side of the screen has a part of the menu that controls notifications and authorization (see Fig. 2.2).

The interface automatically scales to fit the size of the browser window. Additionally, full-screen mode can be activated by selecting Full screen from the drop-down menu in the upper right corner of the interface (see Fig. 2.3). Full-screen mode can also be toggled by pressing the F11 key on the keyboard.

2.2. Diagrams
This main menu item contains a list of diagrams for displaying information being processed by CENTO software. Developing diagrams for displaying information in CENTO software is described in the “Diagrams Development Manual”. Fig. 2.4. - 2.7. show examples of diagrams.[MT1]

The upper right corner of the diagram viewer window has navigation and control buttons.
The scale of the diagrams is adjusted by scrolling the mouse wheel, or by clicking the buttons in the upper right corner of the viewing area Zoom in 
or Zoom out 
The Scale button 
is used to adjust the size of the diagram within the screen automatically.
The displayed diagrams can be printed or exported to separate files with a .png extension and saved on a local computer. Please note, such files are immutable and serve to display data for a certain period. To do this, click the Export button 
in the right side of the screen.
The icon 
means that a diagram has hidden objects, which can be seen by clicking this icon. Usually, these clarifying data are hidden by default to avoid cluttering the diagram.
The Set grounding icon 
is created by the installer on electrical diagrams if installing the portable grounding is needed. To use it, click on the icon, the mouse pointer turns into a grounding symbol. Left-click in the place where grounding is to be installed, then fill in the Portable grounding pop-up window (see Fig. 2.8).

The Dispatch marks icon allows opening the dispatch marks log (see Fig. 2.9), which displays a list of all objects with dispatcher tags assigned to them. The tree on the left side of the screen allows selecting an object, and its tags are displayed on the right side of the screen.
Figure 2.9. Dispatch marks log
In the same interface, assigned tags can be removed using the Remove button. It is also possible to download the list of changes in Excel format.
The Playback mode icon 
enables the diagram history viewing mode. After clicking on this icon, the playback interface appears on the bottom of the screen (see Fig. 2.10). Here the user can select the time in the calendar and click on the Play button 
. As a result, the diagram displays dynamic state of all objects in the time selected by the user.

If the user has the right to edit diagrams, the Edit button 
is displayed on the right in the viewing area. When clicked, the displayed diagram opens with the built-in diagram editor menu. Switching between diagrams is done in the Active schemes tree displayed in the left part of the screen when the button 
is pressed (see Fig. 2.11).
In the Active schemes menu, the user can use the minimize tree button
as well 
as the tree display settings button to choose whether to display objects according to the settings of the diagram positions (this function is only available if the user has administrator rights).
The icon 
pins the active diagram window so that the user cannot open the list when switching between the diagrams.
