30 === 2.1. Creating a device tree ===
31
32 Configuration begins with the creation of a tree of devices (sources of information). The device tree is formed based on the convenience of further work with this tree and can reflect either the structure and names of the places where information sources are installed, or (in the case of small projects) combine information sources and production facilities of the enterprise.  This tree is necessary for the subsequent attribution of all sources of information and the information itself to this structure.
33
34 To configure the structure, go to the "Devices, tags, channels" page (Settings – Devices, tags, channels) (see Fig. 2.2).

40 By default, CENTO has a "Root Object" preset. Under the root object, you can specify, for example, the name of a company or a separate object. In order to rename a tree element, you need to hover the mouse pointer over it and right-click, and then select "Edit" (see Fig. 2.3). You can also delete an unnecessary object by clicking on the button [[image:1762746580637-301.png]]

47 **Attention! There must be no tethered devices in the power facility for removal.**
48
49
50 Adding objects in the structure (name of the system or enterprise) is performed by right-clicking (hereinafter referred to as the "RMB") on:
51
52 * Selected object in the tree, in which case the new object will be nested;
53 * In the empty space of a given tree, in this case, the new object will be an independent object in this structure.
54
55 The sequence and nesting of objects in the tree can be adjusted by dragging objects by holding down the left mouse button (see Fig. 2.4), as well as by using [[image:1762746645908-483.png]] and [[image:1762746672090-269.png]]selecting the desired object in the tree (see Fig. 2.5).

169
170 === 2.3. Set up tags and channels ===
171
172 In CENTO software, information is divided into 2 types: tags and channels.
173
174 Tags are data, conditionally, "real-time". That is, data collected from sources of information with the lowest possible delays. The frequency of updating the value of each tag depends on the settings you set, the technical features of the data sources, and their capabilities. For example, in dispatching systems, data is updated once per second, but it can be both more frequent and less frequent (for example, it may depend on how much the value itself has changed).
175
176 Channels are data used for metering (electricity, other energy resources, operating time, products, etc.). A feature of metering channels is a clearly defined discreteness of information (for example: 1 minute, 3 minutes, 30 minutes, 1 hour, etc.). The value of the channel is recorded as an increment of a value for a given period, averaging for a given period and a value at the end of the period. In metering systems, information is most often transmitted in this form by the data sources themselves (meters, heat calculators, etc.), but accounting channels can also be formed in CENTO itself based on tag values. The use of information in the form of "channels" in accounting allows you to receive information from data sources even in case of failures in communication channels (data can be obtained from the archive after the connection is restored), it is convenient to work with data, and generate various reports.
177
178 Tags and accounting channels are configured on the same page "Devices, tags, channels" ("Settings" - "Devices, tags, channels") on the "Tags, channels" tab (see Fig. 2.10).

182 Fig. 2.10 – Parameter Description Page
183
184 On the "Tags, Channels" tab, when selecting one or more devices, all tags and channels of device data accounting are displayed in a tabular form. In this table, you can perform the following operations for each signal separately:
185
186 * Create a tag or channel by clicking [[image:1762749527914-134.png||height="20" width="117"]] the button in the upper right corner of the screen.
187 * the button [[image:1762749527915-501.png||height="21" width="69"]] allows you to export data on selected tags to an excel table, completely repeating columns and rows from "Tags, channels", while this uploaded file serves only for analysis, not configuration;
188 * The button [[image:1762749527915-879.png||height="21" width="85"]] allows you to upload/download an Excel file with selected tags, in which you can remove/add tags to specific devices without downloading the entire configuration from the page from section 3 of this manual;
189 * Go to the tag or channel editing window by clicking the left mouse button on the tag name or its ID;
190 * viewing the values of tags and channels and going to the graph page of the required parameter by clicking the left mouse button on the value;
191 * enabling and disabling tag (channel) polling by radio buttons in the "Status" column;
192 * viewing the status of the tag (channel) and its polling;
193 * viewing the time of the last update of the tag (channel) survey – the date and time (in the format "yy-mm-dd hh:mm:ss") of the last successful receipt of the tag (channel) value (the value of the tag or channel itself may not have changed);
194 * copying and deleting tags and channels by clicking buttons [[image:1762749562010-279.png||height="25" width="25"]] and [[image:1762749562011-728.png||height="24" width="24"]] respectively.

456 ==== 2.3.4. Configuring calculation channels ====
457
458 CENTO has the ability to create calculated accounting channels. A calculated channel can be created either based on the values of other channels or on the basis of tag values. In order to create a calculation channel, you need to go to the link "Settings" - "Devices, tags, channels" - "Calculation channels" (see Fig. 2.15).
459
460 [[image:Screenshot 2025-11-09 at 21.58.58.png]]
461
462 Fig.2.15 – List of calculation channels
463
464 On the "Billing channels" tab, when you select one or more devices, all billing channels for metering these devices are displayed in a tabular form. In this table, you can perform the following operations for each parameter separately:
465
466 * Create a channel by pressing a button [[image:1762754384286-528.png||height="24" width="121"]] and [[image:1762754384287-151.png||height="26" width="114"]] in the upper right corner of the screen.
467 * Go to the channel editing window by left-clicking on the tag name or tag ID.
468 * View channel values and go to the graph page of the required parameter by clicking the left mouse button on the value.
469 * enabling and disabling channel polling by switches in the "Status" column.
470 * viewing the status of the settlement channel.
471 * viewing the time of the last update of the tag (channel) poll – the date and time (in the format "yyyy-mm-dd hh:mm:ss") of the last successful receipt of the tag (channel) value (the tag or channel value itself may not have changed).
472 * copying and deleting channels by pressing buttons [[image:1762754384287-453.png||height="21" width="21"]] and [[image:1762754384287-190.png||height="22" width="22"]] respectively
473 * preliminary check of the formula [[image:1762754384287-268.png||height="27" width="26"]]
474 * filter by category
475 * filter by formula
476 * filter by device.
477
478 More detailed use of calculation channels is described in the "Guide to setting up accounting channels".
479
480 == 3. CONFIGURING CENTO VIA EXCEL ==
481
482 The CENTO software provides the ability to configure the system via Excel files. The interface of this functionality is located on the Downloading/Uploading Configuration Files page (Menu item "Settings" – "Configuration Files"). (see Fig. 3.1).
483
484 [[image:Screenshot 2025-11-09 at 22.02.21.png]]
485
486 Fig. 3.1– Download/Upload Configuration Files Page
487
488 With the help of Excel files, you can configure:
489
490 1. Devices (also device tree and device types);
491 1. Tags and channels;
492 1. Events;
493 1. Information model (classes, elements, reference books);
494 1. Telecontrol Lock Conditions;
495 1. Accounting Channels.
496 1. Tabular data directories.
497 1. Alarm event recorders.
498
499 A .xlsx file with strictly defined tabs and columns is uploaded from this page with a single button. File correction is possible both through Excel and through other programs that work with the .xlsx table format, for example, LibreOffice. With another button, these files are uploaded to the server. After downloading, you need to apply the changes made by clicking the "Update configuration" button in the drop-down menu in the upper right corner of the page, as in Fig.3.2.

502
503 Fig. 3.2– Update Configuration Button
504
505 In addition to the web interface, power facilities and device types can be edited through the "Devices" table. On the first tab "List of objects" there is a table as in Figure 3.3
506
507 [[image:Screenshot 2025-11-09 at 22.04.17.png||height="194" width="384"]]
508
509 Fig. 3.3 – Table "List of objects"
510
511 The Object ID column contains unique numbers of the enterprise's power facilities. Their names are displayed in the "Object name" column. The "Parent Object ID" column determines where the power object will be located in the object tree, and if the cell is empty, then the object will lie at the root of the tree. Thus, the table shown in Figure 3.3 corresponds to the tree shown in Figure 3.4.
512
513 [[image:Screenshot 2025-11-09 at 22.05.26.png||height="300" width="238"]]
514
515 Fig. 3.4 – Tree of power facilities
516
517 The "Sorting" field determines where objects belonging to the same "parent" will be located relative to each other.
518
519 Adding new power facilities is carried out taking into account the ID of existing objects in the table. Object IDs must not be repeated.
520
521 The Device Types tab displays the device types available on the server (see Figure 3.5).
522
523 [[image:Screenshot 2025-11-09 at 22.06.17.png||height="286" width="268"]]
524
525 Fig. 3.5 – Table "Device Types"
526
527 The ID column of the device type displays the unique number of the device type, and the name column displays its name. To add new types, you must follow the numbering.
528
529 Editing other tabs in the Devices table and the Tags and Channels file is described in the setup guides for specific protocols and device types.
530
531 Setting up Events files is described in the Event System Configuration Guide.
532
533 The "Information Model Classes", "Information Model Elements" and "Information Model References" files are configured according to the "Information Model Setup Guide".
534
535 The rules for filling in the file "Telecontrol lock conditions" can be found in the "Remote Control Lock Settings Guide".
536
537 Working with accounting channels is described in the "Guide to setting up accounting channels".
538
539 The "Logger Settings" file is configured according to the "Alarm Event Recorder Configuration Guide".
540
541 "Tabular data references" are used in the mode calculation module, so their settings are specified in the "Mode Calculation Module Setup and Operation Manual".
542
543 == 4. EVENTS ==
544
545 "Events" in CENTO are designed to increase the observability of the system by tracking changes in the state of process equipment, recording changes in the event log and alerting users.
546
547 Events help personnel to respond in a timely manner to changes in the technological process and system operation.
548
549 * Event settings are located in the "Event Editor" menu item (see Fig. 4.1). Events that are configured on this page are included in the archive log of technological events, as well as in the operational log. For a more detailed description of the Event Editor page and how to configure technology events, see the Event System Setup Guide.

Available for viewing by the User are located in the tree of active mnemonic diagrams by clicking on the main menu of the CENTO software under the item [[image:1762755230293-190.png||height="21" width="120"]]
565
566 Mimic diagrams display data from the polled devices, their tags and channels, in various forms of display (graphs, tables, reference information, animations of graphic elements, etc.).
567
568 More detailed use of mnemonic diagrams, their creation and configuration are described in the "Guide to the development of mnemonic diagrams".
569
570 == 6. INFORMATION MODEL ==
571
572 An information model is a tool for describing the object of automation (physical objects, equipment, processes, etc.).  The information model allows you to reflect the structure and consolidate information on each created object in the form of attributes (measurements, reference values, regulatory documentation, etc.). The information model is widely used in CENTO: to simplify the configuration of large systems, to implement various functions, to differentiate rights by objects.
573
574 The IM can be configured in the web editor "Information Model Editor" (see Fig. 6.1).

721 === 11.1. Analysis of real-time data ===
722
723 On the page "Analysis of operational data" ("Analysis" - "Operational data") there is a tab "Time" (Fig. 12.1), which is designed for time control on devices capable of transmitting their internal time to CENTO. In order for such devices to appear in the interface, time is collected from them into a tag with a name, for example, "Device time" in a string in the format YYYY-MM-DD HH:MM:SS.  Next [[image:1762756612986-850.png||height="24" width="25"]] , the system will find all tags with this name and compare the time specified in them with the time of the last polling of the device. The difference will be displayed in the right column and will give the User an understanding of how many seconds the time of the device differs from the server time.

745 [[image:1762756832283-936.png]] - Log display configuration button (down left corner). By default, it is present only in the User interface with Administrator rights. Clicking this button opens a pop-up window (Fig. 12.4), in which the User sets the height of the rows in the log, the method of displaying the paths to the device and the IM object: chooses how many levels to display starting from the device or hide starting from the root of the tree, the same choice with the tree of objects of the information model. Selects the alignment in the columns (centered, left, or right). It also edits the display/hiding of columns and their placement relative to each other by dragging and dropping the icon [[image:1762756832283-360.png]]
