Lana 12.1 15 === 2.1. Creating a device tree ===
Lana 10.2 16
Lana 12.1 17 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.
18
19 To configure the structure, go to the "Devices, tags, channels" page (Settings – Devices, tags, channels) (see Fig. 2.2).

Lana 67.2 155 === 2.3. Set up tags and channels ===
Lana 66.2 156
Lana 67.2 157 In CENTO software, information is divided into 2 types: tags and channels.
Lana 66.2 158
Lana 67.2 159 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).
Lana 66.2 160
161 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.
162
163 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).

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.

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.

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).

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.

553 More detailed use of mnemonic diagrams, their creation and configuration are described in the "Guide to the development of mnemonic diagrams".
554
Lana 116.2 555 == 6. INFORMATION MODEL ==
Lana 115.2 556
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).
