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

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.
Figure 2.10. Diagrams player interface
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, allowing the user to switch between diagrams without reopening the list each time.

The diagram developer provides properties of objects on a diagram available to the user. These properties are available both by a left mouse click (see Fig. 2.12) and a right mouse click.
Left-clicking opens a brief passport of the object containing all its attributes. Depending on the settings, it can be data from several devices linked to the information model (see “Information Model. Setup Manual” for details), or data from one device, or data from one tag, as well as a description of the resulting values. Clicking on a value will take the user to the real-time data analysis to view the chart of the value.
Figure 2.12. Object menu available with left click
Right-clicking on an object opens a context menu with the following available items.
Figure 2.13. Object context menu is accessible with a right click
Measurements mean a full passport of the object (see Fig. 2.14). It contains a set of values similar to the short passport but in an extended form. In addition to the names of the tags and their values, this passport shows the id/codes of the tags, their statuses, the devices from which the tags are collected and the path in the device tree. Time of last tag modification (time when its value was changed) and time of last tag update (time of last successful retrieval of the tag value, the tag value itself may not have changed). The Manual entry column allows entering manually a value into the tag. If the tag has a description, the user can choose which value to select from the drop-down list.
The Setpoints button in the top right corner of the window opens the user interface for setting the setpoints presented in the tag passport. Here the user can modify these settings, add new ones or delete old ones.
The passport header shows the path to the object in the Information Model (IM) tree. The second line shows the object class name and object ID in the IM.

Video is a menu item that, when clicked, opens the view of the video stream from the video surveillance camera (Fig. 2.15). The user can drag the video camera window on the diagram, resize it, open it in a separate window, as well as go to the general log of the object by left-clicking the icon 
Figure 2.15. Viewing video stream
Telecontrol is discussed in detail in the next paragraph of this manual.
Dispatch marks is a menu item that opens the window for adding dispatch marks. There are four types of marks: info, grounded, ban operation, and admission work. The user with appropriate rights can add, modify, and delete marks. Added marks are displayed as corresponding icons next to the object in the diagram and can be also used to block telecontrol of the object.
Figure 2.16. Dispatch marks interface
Reference information is a menu item that opens the help information window (Fig. 2.17). Help can store various object data, contacts of the service personnel, equipment characteristics, links to documents, and orders. With the appropriate rights, the information in the help can be modified directly in the diagram.
Figure 2.17. Reference information
Operative events journal is a menu item that opens the event log for a specific object. This log is like the Real-time data log (see paragraph 2.6 of this manual), except that it displays the last 100 events of an object selected by a user rather than the whole enterprise. The button
clicked opens the general log with events already filtered by object (see paragraph 2.4 of this manual) to see the whole history. Other display settings are like those of the Operative events journal.
Figure 2.18. Object log
2.2.1. Control
Users with the appropriate permissions can control objects in CENTO. By default, the system grants this permission to users assigned the Dispatcher role.
Control is available in the Devices, channels, and tags editor (used during the system configuration stage and described in the “Control Setup Manual”), as well as using the diagrams.
On the diagram, when right-clicking a control object, a modal window appears. Depending on the settings and types of control objects, this window includes either a Telecontrol option (typically for objects with the On/Off control type, see Fig. 2.19) or an option named according to the control type (for objects that support numeric control commands, see Fig. 2.20).
