13 Users, including the administrator, log in to CENTO through a web interface. The software supports web browsers such as Google Chrome, Microsoft Edge, etc.
14
Lana 81.2 15 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>>url:http://192.168.80.10/]] or [[https:~~/~~/demo.centosoftware.com/.>>url: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** in the web browser's address bar.
Lana 3.2 16
17 After entering the address, the user is redirected to the authorization page, which includes fields for username and password input (see Fig. 1.1).

23 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.
24
25 If the login is successful, the web browser displays the CENTO software web interface panel (see Fig. 2.1).

31 If necessary, the system administrator can set any other CENTO interface page as the start page for each user role.
32
33 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.
34
35 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).

43 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).

146
147 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 [[image:Screenshot 2025-11-12 at 14.42.57.png]] in the right side of the screen.
148
149 The icon [[image:Screenshot 2025-11-12 at 14.43.30.png]] 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.
150
151 The **Set grounding** icon [[image:Screenshot 2025-11-12 at 14.44.11.png]]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).

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.

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.

233 Users with the appropriate permissions can control objects in CENTO. By default, the system grants this permission to users assigned the Dispatcher role.
234
235 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.
236
237 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).

Lana 108.2 392 The right part of the screen (for both the Device and Object trees) has a window with three tabs: **Real-time data, Chart, Table.** The **Real-time data** tab is enabled by default. It contains a table of tags selected in the //Device tree,// or the //Object tree;// or a table of protocol and device statuses if the **Statuses **tab is opened.
Lana 96.2 393
Lana 108.2 394 The **Tag** table (see Fig. 2.31) contains the following information:

Lana 108.2 398 Figure 2.31. Tag table in the Real-time data analysis
Lana 96.2 399
Lana 108.2 400 **ID/Code **is a tag identifier in the CENTO software configuration; ID is a mandatory unique parameter of the tag; code is an optional unique parameter of the tag. Clicking the button [[image:Screenshot 2025-11-12 at 19.06.51.png||height="24" width="23"]] allows to search by ID or code. Clicking the ID or code allows you to change the displayed identifier.
401
402 **Status **is an icon of the status (see the decoding in Table 2.2). It displays the time when the status value was last changed when the mouse pointer is moved.
403
404 **Name **is a tag name. Click the button [[image:Screenshot 2025-11-12 at 19.08.00.png||height="26" width="25"]] to search by tag name.
405
406 **Value **is the last received tag value. It displays the time when the value was last changed when mouse pointer is moved.
407
408 This field is used for manual input. To perform manual input, it is necessary to click the value with the left mouse button, enter a new value, and two icons [[image:Screenshot 2025-11-12 at 19.08.59.png||height="30" width="55"]]will appear in the right part of the field. Clicking on the first one performs the manual input until the value is received from a device. Clicking on the second one performs the manual input until cancelled by the user.
409
410 **Object **is the name of the object to which the tag is attached. Click the button [[image:Screenshot 2025-11-12 at 19.09.37.png||height="24" width="24"]] to search by object name.
411
412 **Device **is the name of a device from which a tag comes. Click the button [[image:Screenshot 2025-11-12 at 19.09.37.png||height="24" width="24"]] to search by device name.
413
414 **Last update time **is the date and time (in the format "yyyy-mm-dd hh:mm:ss") of the last successful tag value update (the tag value itself may not have changed).
415
416 The **Chart** tab displays the values of the tags selected in the //Device Tree// or the //Object Tree //in graph form (see Fig. 2.32)

Lana 121.4 432 The button [[image:Screenshot 2025-11-12 at 19.14.57.png||height="28" width="28"]] opens the **Chart settings** menu (see Fig. 2.34). This menu allows selecting the chart type (columns or stepline) and its location (on one axis or on different axes). The user's choice of chart settings is remembered by the browser, and the next time the page is visited, the chart opens with the same settings.

Lana 113.2 450 A file with the extension '.xlsx' is downloaded in XLS format. A zip archive containing two files: data.csv and meta.csv is downloaded in CSV format. The data.csv file contains tag IDs, timestamps, tag values and statuses. The meta.csv file contains the paths of selected tags in the device or object tree, measurement units and tag IDs.

Lana 115.2 456 The user can add messages to the chart if they have the appropriate rights. To do this, place the mouse pointer on the chart, wait for the circle to appear, and click the left mouse button. A pop-up window will appear (see fig 2.36) where the user can enter a message, the type of event, and its severity level. After clicking **Save**, a label with the pop-up message appears on the chart. A new line containing the new event will appear in a separate log (paragraph 2.4.7).
