5 CENTO is a multifunctional software platform for data acquisition, processing and display. This manual describes how to configure the CENTO user tool Control.

7 It is assumed that the user, having read the "User manual", is already familiar with the basic elements of the CENTO interface.

9 This manual describes how to configure the Control service, which is used to send control commands to the objects being controlled.

15 A user with the appropriate permissions can control the object using the devices, tags, channels editor.
16
17 By default, for security reasons, in CENTO software, the Administrator role is not authorized for telecontrol and control operations, and the Dispatcher role does not have access to the devices, tags, and channels editor. To enable control and telecontrol using the editor, configure a custom role. For example, duplicate the Dispatcher role and assign it the necessary permissions to access and use the editor.
18
19 To control the device, navigate to the **Tags, channels** tab on the **Devices, tags, channels** page accessible in the menu: Settings > Devices, tags, channels. In the tree structure, locate the device whose parameters are to be controlled. All the tags with preconfigured control functionality will display either a **C** button (see Fig. 2.1) or a **TC** button (see Fig. 2.2) in the **Control** column.
20
21 **C** is an abbreviation for //Control//. **TC** is an abbreviation for //Telecontrol.// In CENTO software, //Control// refers to sending a non-negative integer value to a device, while //Telecontrol //refers to sending a discrete signal.

60
61 Setting control for tags transmitted via Modbus, OPC DA, or IEC-104 protocols is performed through the **Edit parameter** interface located under Settings > Devices, tags, channels, in the **Tags, channels** tab. In this interface, select the target device in the device tree by checking the box next to it. The device should be configured with one of the supported protocols: Modbus TCP, Modbus RTU over TCP, OPC DA, or IEC-104. To open the tag editing interface, click on the tag identifier or tag name in the general tag list.

63 The interface includes protocol-dependent fields:

71 * Remote control (discrete signal transmission to the device) for IEC-104 protocol: "Remote control is allowed", "Select before operate (SBO)", "Function", "Command duration", "Switch on address", "Switch on value", "Switch off address", "Switch off value", for Modbus TCP protocol: "Remote control is allowed", "Function", "Value length", "Switch on address", "Switch on value", "Switch off value", "Switch off address", "Write by bitmask";
72 * Control (transmission of a positive integer to the device) for Modbus TCP protocol: "Record values", "Function", "Data type in device", "Address", "Byte order", conversion elements: "Physical value (lower limit)", "Physical value (upper limit)", "Value to record (lower limit)", "Value to record (upper limit)", for OPC DA protocol: "Record values", "Device Tag Data Type", conversion elements: "Physical value (lower limit)", "Physical value (upper limit)", "Value to record (lower limit)", "Value to record (upper limit)".

74 1. The remote //control// function is available for Modbus TCP Modbus RTU over TCP) protocols (see Fig. 3.1.1) and IEC 104 (see Fig. 3.1.2).
75
76 The position of the **Remote control is allowed **switch determines whether record commands can be sent to the device at the specified address.
77
78 The position of the **Select before operate (SBO)** switch defines whether command selection is required prior to executing telecontrol commands.
