67
68 Users, including the administrator, log in to CENTO through a web interface. The software supports web browsers such as Google Chrome, Microsoft Edge, etc.
69
70 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.
71
72 After entering the address, the user is redirected to the authorization page, which includes fields for username and password input (see Fig. 1.1).

77
78 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.
79
80 If the login is successful, the web browser displays the CENTO software web interface panel (see Fig. 2.1).

85
86 If necessary, the system administrator can set any other CENTO interface page as the start page for each user role.
87
88 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.
89
90 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).

96 As a result, the user is redirected back to the authorization page (see Fig. 1.1).
97
98 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).

200 The **Scale **button [[image:Screenshot 2025-11-12 at 14.41.36.png]] is used to adjust the size of the diagram within the screen automatically.
201
202 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.
203
204 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.
205
206 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).

236 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.
237
238 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.

250 **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.
251
252 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.
253
254 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.

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[[image:Screenshot 2025-11-12 at 18.35.41.png]] clicked opens the general log with events already filtered by object (see paragraph 2.4 of this manual) to see the whole history.

286 ==== 2.2.1. Control ====
287
288 Users with the appropriate permissions can control objects in CENTO. By default, the system grants this permission to users assigned the Dispatcher role.
289
290 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.
291
292 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).

551 ==== 2.3.2. Metering data analysis ====
552
553 CENTO has tools for working with metering data (electricity, energy resources, operating hours, emissions, etc.). Data is presented to the user in both tabular and graphical formats. Users can choose the chart display style, the period for which data should be shown, aggregate data, and generate reports and data tables in Excel format.
554
555 To view historical metering data, select **Metering data** from the **Analysis **drop-down menu. This opens the **Analysis of data metering** page (see Fig. 2.40 - Fig. 2.41).

563 Figure 2.41. Analysis of the data metering page
564
565 The top section of the left side of the screen displays the **Devices** and **Objects** tabs.
566
567 Depending on configured access rights, the user may have access to both tabs (**Devices** and **Objects**), to only one of them, to specific devices or objects only, or access to both tabs may be completely restricted, the tabs are hidden from the interface.
568
569 The **Devices** tab mirrors the structure of the main device tree, with an exception - it displays only those devices that collect metering data.
570
571 The **Objects** tab appears when the object tree is configured in the information model containing metering points and calculated channels. Using the information model allows metering points to be associated with various categories and types of consumers, production units, etc. The use of the **Objects** tab is described in more detail in the “Balances Setup Manual”.
572
573 In all other respects, working with the //Devices tree //and the //Objects tree// is identical. To view metering data, locate it in the tree and check the corresponding box. After that, all channels will be displayed in the right-hand panel of the interface. Search either by browsing the tree or using the search bar available. The button [[image:1763008022531-642.png]] resets all search results and collapses the tree to its original state.
574
575 The charts displayed in the right-hand panel can be aggregated using the aggregation drop-down menu (see Fig. 2.42). Several intervals are available, from one hour to one year. After selecting an interval, a window appears to select an aggregation function: sum, average, minimum, or maximum. It is important to note that the aggregation function is applied only to interval values.

587 Below the chart are navigation buttons and display control fields. The left field [[image:Screenshot 2025-11-12 at 20.30.13.png||height="27" width="86"]] specifies how many charts to display per page. By default, this is 5; the maximum is 15. The **Back** and **Forward** buttons scroll through the days for which the chart is displayed. On the right side [[image:Screenshot 2025-11-12 at 20.31.16.png||height="23" width="65"]] , navigation allows switching between pages if all selected charts do not fit on a single page.
588
589 The **Table** tab displays the same data shown in the charts but in tabular form. Additionally, if the user has the appropriate permissions, manual data entry is available. To enter data, hover the cursor over the desired cell in the table, left-click, and enter the new value. Then, a **Save value **appears on the right side of the input field. Click this icon or press **Enter** on the keyboard to save the value to the CENTO database. For devices that support only manual data entry, CENTO has a function to automatically fill in cells between two manually entered values. For example, if readings are entered for 10:00 and then for 20:00, the system automatically fills in all intermediate half-hour intervals, as well as the corresponding energy and power values.
590
591 Manual entry of metering data is also available using Excel or another suitable editor, as described below.
592
593 Above the chart area, on a gray bar, the **Download, Upload, Share** buttons, and a calendar are displayed.
594
595 The calendar [[image:Screenshot 2025-11-12 at 20.32.25.png||height="29" width="159"]] allows selecting the time interval for which the chart will be displayed (see Fig. 2.44). Fixed intervals are also available to the left of the calendar field. The reset button restores the current date in the calendar.

603 The **Download **[[image:Screenshot 2025-11-12 at 20.34.21.png||height="26" width="94"]] button allows downloading the selected metering channels to the user's computer in .xlsx format.
604
605 The downloaded file can be used for manual entry of metering data. To perform manual entry, open the file in an editor (Excel or another suitable application). Then enter the new data into the fields, mark them in bold font, and save the file. Next, upload the saved file by clicking the **Upload** button [[image:Screenshot 2025-11-12 at 20.35.04.png||height="28" width="73"]]in the CENTO interface. This opens the file upload window with instructions (see Fig. 2.45)

620
621 Analysis of the receipt of data is a table containing a list of available devices with their ID numbers and codes, as well as the number of time intervals for which the server has received data from the metering devices relative to the total number of intervals (see Fig. 2.47).
622
623 The left panel displays a device tree like the one in the **Analysis of data metering** interface. Each object shows the number of received and expected intervals. If the numbers match, both are displayed in the same color. If any intervals are missing, the first number is highlighted in red. Devices or objects can be located either through the tree or by using the search bar.
624
625 To the right of the search bar, there are two icons. The **Reset **icon [[image:Screenshot 2025-11-12 at 20.38.26.png||height="29" width="26"]] clears the previous search results and collapses the tree. The **Filter** icon [[image:Screenshot 2025-11-12 at 20.38.55.png||height="28" width="25"]] enables filtering by collected channels. When the **Data gaps** checkbox is selected, only those devices with missing data will remain visible in the tree. This functionality simplifies the process of identifying devices with missing data for subsequent re-polling.
626
627 In the right section of the interface, data receipt profiles for each device are generated based on the received intervals.

631 Figure 2.47. Pop-up tooltips on the data receipt chart
632
633 The first column of the table contains either the device ID or code, which can be toggled between. Next, the device name (channels) is displayed.
634
635 The third column shows the data availability profile. When hovering the mouse pointer over the upper breakpoints of the chart (see Fig. 2.44), a tooltip displays the time when the last interval before the gap was received (the first interval after the gap). The tooltip at the lower breakpoints shows the time of the first (or last) interval within the data receipt gap.
636
637 The fourth column shows the ratio of received intervals to the number of expected intervals.
638
639 Above the table, there are two buttons:** Interrogate** and **Refresh.**
640
641 The **Interrogate **button sends a request to the polling service to retrieve the archive from the selected device for the specified interval. After pressing the button, a message appears on the screen indicating the number of devices being polled and the time interval. If a warning appears stating that the operation may take a long time (see Fig. 2.48), reduce the number of devices or shorten the polling depth.

647 The **Refresh** button [[image:Screenshot 2025-11-12 at 20.40.59.png||height="28" width="84"]] re-polls data from the database for the status.
648
649 In addition to the **Refresh** and **Interrogate** buttons, a **Calculate** button may appear on the gray interface panel. This button appears when devices bound to calculated channels are selected in the tree. These calculated channels display similarly to regular ones, but their data is derived from other channels or tags. If a calculated channel is based on data from other channels, it can be recalculated using the **Calculate **button. This functionality is necessary when the source data or formula of such a channel has changed.
650
651 At the very top of the interface on the gray panel, there is a calendar like the one in the **Analysis of data metering** section.
652
653 The **Receipt of metering data** interface depends on the user’s configured access rights.
654
655 ==== 2.3.4. **Device diagnostic** ====

865
866 The size of the journal window can be adjusted by dragging the lower right corner while holding down the left mouse button.
867
868 To recognize the type of event and its severity level, each line of the operative journal has an icon characterizing the event in the beginning. These icons can be modified or supplemented during system setup.
869
870 When selecting the **All events** tab in the left area of the **Operative events journal,** the last 100 events formed by the system are displayed on the right side of the journal.
871
872 There are two types of events in CENTO software: single and with return. The with return events allow displaying events in the active state in a separate tab (for example, //ground in a network with an isolated neutral, Opening an emergency exit door//). An event reporting the triggering of this important state is given the status //Active//. An event that signals the end of an important state removes the// Active// status from the first event.
873
874 These two events are with return: the second event closes the first one.
875
876 The remaining events (regardless of their importance) are classified as single events.
877
878 The tab [[image:Screenshot 2025-11-12 at 22.31.11.png||height="27" width="71"]] of the **Operative events journal **shows active events on the right side of the window. Both events (active and closing) are displayed in the log of all events independently of one another.
879
880 The events can be communicated to the user (by sound and pop-up alerts) on the diagrams. Depending on the settings, the alerts can last for a specified time or until the user reacts to them. The last ones are called acknowledgeable.
881
882 The number of unacknowledged events is displayed on the operative events journal icon of the main menu: [[image:Screenshot 2025-11-12 at 22.31.47.png||height="29" width="34"]]
883
884 Acknowledged events are displayed in a general list in the log of all events. To see all unacknowledged events separately, go to the **Operative events journal.**
885
886 To acknowledge this event, the user has to click on the icon [[image:Screenshot 2025-11-12 at 22.32.29.png||height="24" width="25"]]in the line of the event.
