441 +==== 2.3.4. Configuring calculation channels ====
442 +
443 +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).
444 +
445 +[[image:Screenshot 2025-11-09 at 21.58.58.png]]
446 +
447 +Fig.2.15 – List of calculation channels
448 +
449 +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:
450 +
451 +* 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.
452 +* Go to the channel editing window by left-clicking on the tag name or tag ID.
453 +* View channel values and go to the graph page of the required parameter by clicking the left mouse button on the value.
454 +* enabling and disabling channel polling by switches in the "Status" column.
455 +* viewing the status of the settlement channel.
456 +* 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).
457 +* 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
458 +* preliminary check of the formula [[image:1762754384287-268.png||height="27" width="26"]]
459 +* filter by category
460 +* filter by formula
461 +* filter by device.
462 +
463 +More detailed use of calculation channels is described in the "Guide to setting up accounting channels".
464 +
465 +== 3. CONFIGURING CENTO VIA EXCEL ==
466 +
467 +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).
468 +
469 +[[image:Screenshot 2025-11-09 at 22.02.21.png]]
470 +
471 +Fig. 3.1– Download/Upload Configuration Files Page
472 +
473 +With the help of Excel files, you can configure:
474 +
475 +1. Devices (also device tree and device types);
476 +1. Tags and channels;
477 +1. Events;
478 +1. Information model (classes, elements, reference books);
479 +1. Telecontrol Lock Conditions;
480 +1. Accounting Channels.
481 +1. Tabular data directories.
482 +1. Alarm event recorders.
483 +
484 +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.
485 +
486 +[[image:Screenshot 2025-11-09 at 22.03.16.png||height="248" width="232"]]
487 +
488 +Fig. 3.2– Update Configuration Button
489 +
490 +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
491 +
492 +[[image:Screenshot 2025-11-09 at 22.04.17.png||height="194" width="384"]]
493 +
494 +Fig. 3.3 – Table "List of objects"
495 +
496 +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.
497 +

499 +
500 +Fig. 3.4 – Tree of power facilities
501 +
502 +The "Sorting" field determines where objects belonging to the same "parent" will be located relative to each other.
503 +
504 +Adding new power facilities is carried out taking into account the ID of existing objects in the table. Object IDs must not be repeated.
505 +
506 +The Device Types tab displays the device types available on the server (see Figure 3.5).
507 +
508 +[[image:Screenshot 2025-11-09 at 22.06.17.png||height="286" width="268"]]
509 +
510 +Fig. 3.5 – Table "Device Types"
511 +
512 +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.
513 +
514 +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.
515 +
516 +Setting up Events files is described in the Event System Configuration Guide.
517 +
518 +The "Information Model Classes", "Information Model Elements" and "Information Model References" files are configured according to the "Information Model Setup Guide".
519 +
520 +The rules for filling in the file "Telecontrol lock conditions" can be found in the "Remote Control Lock Settings Guide".
521 +
522 +Working with accounting channels is described in the "Guide to setting up accounting channels".
523 +
524 +The "Logger Settings" file is configured according to the "Alarm Event Recorder Configuration Guide".
525 +
526 +"Tabular data references" are used in the mode calculation module, so their settings are specified in the "Mode Calculation Module Setup and Operation Manual".
527 +
528 +== 4. EVENTS ==
529 +
530 +"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.
531 +
532 +Events help personnel to respond in a timely manner to changes in the technological process and system operation.
533 +
534 +* 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.
535 +
536 +[[image:Screenshot 2025-11-09 at 22.07.47.png||height="376" width="319"]]
537 +
538 +Fig. 4.1 – Event Menu
539 +
540 +* In the CENTO software, it is possible to notify users about the occurrence of events by e-mail in the "Notifications" menu item, the description and configuration of this functionality are described in the "Event System Configuration Guide".
541 +* In the "Sound Editor" menu, it is possible to upload files for sound notification of the occurrence of an event, the setting is also indicated in the "Event System Setup Guide".
542 +

548 +
549 +All mnemonic diagrams are developed in the built-in editor, which is located in the menu item "Mnemonics Diagrams" ("Settings" - "Mimic Diagrams" (see Fig. 5.1)). 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"]]
550 +
551 +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.).
552 +
553 +More detailed use of mnemonic diagrams, their creation and configuration are described in the "Guide to the development of mnemonic diagrams".
554 +
555 +== 6. INFORMATION MODEL ==
556 +
557 +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.
558 +
559 +The IM can be configured in the web editor "Information Model Editor" (see Fig. 6.1).
560 +
561 +[[image:Screenshot 2025-11-09 at 22.15.02.png||height="397" width="1060"]]
562 +
563 +Fig. 6.1 – Information Model Editor Page
564 +
565 +With the help of this editor, directories, classes, and objects of the Information Model are created.
566 +
567 +For a detailed description of how to set up an information model, see the Information Model Setup Guide.
