1. INTRODUCTION
CENTO is a multifunctional software platform for data collection, processing, and display.
The CENTO software allows you to create, edit, and view diagrams without installing additional programs.
This Manual explains how to work in the built-in CENTO diagram editor, how to create and configure diagrams as well as how to link diagram elements to objects in the CENTO information model.
It is assumed that the user, having read the "User Manual", "Setup Manual", and "Information Model Setup Manual", is already familiar with the basic interface elements, ways to configure CENTO, and the basic concepts of the CENTO information model.
2. VIEWING DIAGRAMS
Diagrams can be viewed by hovering over
in the CENTO main menu and clicking on the name of a diagram in the drop-down list under the button. The drop-down list contains a list of diagrams available for viewing. An example of a diagram screen with a drop-down list is shown in Fig. 2.1.

Figure 2.1. Diagram with a drop-down list of available diagrams
Zooming of the diagrams is performed by scrolling the mouse wheel, or by clicking the buttons in the upper-right corner of the viewing area Zoom in
or Zoom out
. The Scale
button is designed to automatically adjust the size of the diagram within the screen.
When using CENTO on touchscreen devices or on multi-touch panels, the image is zoomed in or out by double touching and simultaneously changing the distance between the touch points.
The visible portion of the diagram can be repositioned within the interface workspace by clicking and dragging with the left mouse button held down, or by pressing and dragging using the mouse wheel (middle mouse button).
Switching between diagrams is performed in the Active schemes tree displayed on the left side of the screen when the button
is pressed. This tree can be pinned in the viewer by clicking the button
. The diagram currently displayed on the screen is highlighted within the corresponding tree structure
.
The sorting of diagrams and folders (IM objects) depends on the indicated position, see Fig. 2.1, as well as additional settings in the tree itself when the button
is right-clicked.

The tree structure is sorted in ascending order based on the defined positional indices.

The tree structure is organized by folders and additionally sorted in ascending order based on the defined position within each folder.
The displayed diagrams can be exported to .png files, and sent for printing, thereby they serve to display the current state in a certain period. To do this, click on the Export button
on the right side of the screen and select the required menu.
If the user has the right to edit diagrams, then the Edit button
is displayed on the right in the viewing area. When clicking it, the displayed diagram opens in the menu of the built-in editor. Operational guidelines for using the editor are detailed in Section 3 of this manual.
The Settings menu
allows adjustment of the displayed depth of the object path in the header of the Measurements menu table (see Fig. 2.2), as well as the format for displaying instantaneous tag values
. Access to this button is granted based on user permissions.
The Debug mode
allows the diagram designer to configure active templates to display any actions embedded in the logical rules of the elements. After activating this mode, click on the diagram object to be checked. After that, information appears with the attribute code of the IM object, the tag ID number, and its value/quality/status. To apply the values entered in these fields, click on the Apply button
. This mode does not change the tag configuration and does not send a signal of the user’s manual input to the system.

Figure 2.2. Measurements in the debug mode
The playback
mode allows viewing archived data of tag values associated with the diagram. By default, viewing is available for the last 20 minutes, this is the maximum time limit that can be used for any selected period in the calendar drop-down menu. After selecting the date and time, click on the play button
.
When the button
is pressed, the Dispatch marks page is opened (see Fig. 2.3). This interface displays the history of setting and removing dispatch marks. The object tree of the information model (IM) is located on the left side, while the history of mark assignments and removals is shown on the right. The right panel can be exported as a .xlsx table using the button
.
Another button
in the Actions menu removes the mark assigned to the diagram object.

Figure 2.3. Dispatch marks interface
The position of the diagrams and their scale are memorized for each user and device.
The diagram view mode has the functions for:
- switching to the parameter chart when left-clicking its value
- displaying the main parameters of an object when left-clicking it
- displaying the main parameters of an object via the "Measurements" menu when right-clicking it
- remote control of switching devices (if this function is available and the rights are granted)
- viewing a video (if this function is available and the rights are granted)
- installation/removal of dispatcher tags (if this function is available and the rights are granted)
- installation/removal of portable earthing devices (if this function is available and the rights are granted)
- acknowledging events when right-clicking
- viewing events in the operational log.
An example of calling object measurements is shown in Fig. 2.4.

Figure 2.4. Calling object measurements
The Measurements drop-down window consists of the following columns:
- ID/Code is the identification number of the parameter (tag) or its code, depending on the selected item in the drop-down menu, which is remembered even when the page is refreshed. Left-clicking on the ID value redirects to the Devices, tags, channels page under the Tags, Channels tab.
- S is the status of the parameter (tag)
- Name is the name of the parameter (tag)
- Value is the value of the parameter (tag), left-clicking switches to the chart in the real-time data analysis.
- Description displays the description of the parameter value taken from the IM directory
- Device specifies the full path to the device to which the parameter (tag) is linked. Left-clicking redirects to the Devices, tags, channels page on the Devices tab
- The time of the last change
- The time of the last update is the time of the last poll for a tag
- Manual input is a field for entering values manually. Manual input is available before data arrives by selecting
. Once correct tag polling occurs, the manual input is reset, and the actual incoming value is displayed. When the button
is selected, manual input remains visible until it is canceled by the user.
The Measurements drop-down window can be moved from one point to another, as well as adjusted in height. To resize the window, point the mouse cursor to the lower-right corner, and then drag down or up the arrow that appears.
Tag settings can be managed in Measurements. Additional fields are expanded by clicking on the setpoints button
(see Fig. 2.5). The setpoints can only be edited by users who have the right to do so.

Figure 2.5. Setpoints
Clicking on the setpoint opens an additional menu where the status, value, acknowledgment, and the time of insensitivity can be adjusted (see Fig. 2.6). This menu appears both on the already configured setpoints and on the missing ones.

Figure 2.6. Setpoint settings
The object class code and its ID are displayed in the object measurements section (see Fig. 2.7), which is bound to the Information Model (IM). When clicked, the object is redirected to the Information Model editor page. Access to this page is restricted to users with the appropriate rights.

Figure 2.7. Measurements of the IM object
The Measurements table provides the ability to navigate to charts in the Real-time data analysis section, not only for a specific tag value but also for all tags simultaneously by pressing the button ![]()
Tags in the measurements associated with technology events are highlighted with a colored background, as well as with flashing, which allows to quickly navigate which of the parameters of the active object of the diagram is associated with a particular event, see example in Fig. 2.8. The background color of the backlight is the same as that of the animation frame of the active object in the additional settings of the diagram.

allows hiding unpublished or published diagrams within the tree:

Figure 3.3. Hiding diagrams in the tree
The font color of diagram names in the tree depends on their status: active diagrams are displayed with one style
, while inactive ones are shown with another
. Additionally, diagrams without any linked tags are marked in the tree. When hovering over the icon
, a window appears displaying a list of tag IDs:

Figure 3.4. Missing tags
The status of diagrams determines their visibility in the Active schemes tree of the diagram viewer (see Fig. 2.1). New diagrams have the default status disabled.
The Position column indicates the sequence number of the diagram displayed in the Active schemes tree of the diagram viewer (see Fig. 2.1).
In the Object column, the diagram is bound to the objects of the information model, which allows seeing the nesting levels in the tree of the diagram viewer (see Fig. 2.1).
To edit the diagram in the built-in editor, click the button
in the Actions column. The operating rules for the diagram editor are detailed in the next sections of this manual.
The button
in the Actions column is used to copy the diagram URL to the PC clipboard. A link to the diagram is required when configuring its view in the drop-down list
in the CENTO main menu (Settings > System > Menu editor).
The diagram added to the drop-down list of the menu is to be displayed regardless of the status set in the Diagrams window.
