29 CENTO is a multifunctional software platform for data collection, processing, and display.
Lana 5.1 30 CENTO can be used to build various automated systems, for example: dispatching, control, accounting, diagnostics, etc.
31 This guide describes the general steps for setting up CENTO software, as well as links to other instructions.

Lana 12.1 39 === 2.1. Creating a device tree ===
Lana 10.2 40
Lana 12.1 41 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.
42
43 To configure the structure, go to the "Devices, tags, channels" page (Settings – Devices, tags, channels) (see Fig. 2.2).

Lana 15.2 48
Lana 18.2 49 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]]

Lana 67.2 179 === 2.3. Set up tags and channels ===
Lana 66.2 180
Lana 67.2 181 In CENTO software, information is divided into 2 types: tags and channels.
Lana 66.2 182
Lana 67.2 183 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 66.2 184
185 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.
186
187 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).

517
518 Fig. 3.3 – Table "List of objects"
519
520 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.

525
526 The "Sorting" field determines where objects belonging to the same "parent" will be located relative to each other.
527
528 Adding new power facilities is carried out taking into account the ID of existing objects in the table. Object IDs must not be repeated.
529
530 The Device Types tab displays the device types available on the server (see Figure 3.5).

545
546 Working with accounting channels is described in the "Guide to setting up accounting channels".
547
548 The "Logger Settings" file is configured according to the "Alarm Event Recorder Configuration Guide".
549
550 "Tabular data references" are used in the mode calculation module, so their settings are specified in the "Mode Calculation Module Setup and Operation Manual".
551
552 == 4. EVENTS ==
553
554 "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.
555
556 Events help personnel to respond in a timely manner to changes in the technological process and system operation.
557
558 * 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.

Lana 116.2 579 == 6. INFORMATION MODEL ==
Lana 115.2 580
581 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.
582
583 The IM can be configured in the web editor "Information Model Editor" (see Fig. 6.1).

730 === 11.1. Analysis of real-time data ===
731
732 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.

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]]
