3.2	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
81.2	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.
3.2	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).

	95
	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).

60.2	250
60.3	251	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.
	252
	253	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.

68.2	281	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[[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. Other display settings are like those of the Operative events journal.

	287	==== 2.2.1. Control ====
	288
	289	Users with the appropriate permissions can control objects in CENTO. By default, the system grants this permission to users assigned the Dispatcher role.
	290
	291	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.
	292
	293	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).

129.2	566	The top section of the left side of the screen displays the Devices and Objects tabs.
126.4	567
129.2	568	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.
	569
	570	The Devices tab mirrors the structure of the main device tree, with an exception - it displays only those devices that collect metering data.
	571
	572	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”.
	573
	574	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.
	575
	576	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.

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.
133.2	589
134.2	590	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.
	591
	592	Manual entry of metering data is also available using Excel or another suitable editor, as described below.
	593
	594	Above the chart area, on a gray bar, the Download, Upload, Share buttons, and a calendar are displayed.

	620	Figure 2.46. Analysis of the receipt of data
	621
	622	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).
	623
	624	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.
	625
145.2	626	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.
141.2	627
145.2	628	In the right section of the interface, data receipt profiles for each device are generated based on the received intervals.

147.2	632	Figure 2.47. Pop-up tooltips on the data receipt chart
	633
	634	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.
	635
	636	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.
	637
	638	The fourth column shows the ratio of received intervals to the number of expected intervals.
	639
167.2	640	Above the table, there are two buttons: Interrogate and Refresh.
147.2	641
	642	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.

147.3	648	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.
147.2	649
147.3	650	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.
	651
	652	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.
	653
	654	The Receipt of metering data interface depends on the user’s configured access rights.
	655
	656	==== 2.3.4. Device diagnostic ====

	866
	867	The size of the journal window can be adjusted by dragging the lower right corner while holding down the left mouse button.
	868
	869	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.
	870
	871	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.
	872
212.1	873	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.
210.1	874
	875	These two events are with return: the second event closes the first one.
	876
	877	The remaining events (regardless of their importance) are classified as single events.
	878
	879	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.
	880
	881	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.
	882
	883	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"]]
	884
