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.
62 +
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)".

76 +
77 +The position of the **Remote control is allowed **switch determines whether record commands can be sent to the device at the specified address.
78 +
79 +The position of the **Select before operate (SBO)** switch defines whether command selection is required prior to executing telecontrol commands.
80 +
81 +In the Remote **control **field, select the appropriate ASDU type for the control command from the drop-down list (see Fig. 3.1.4).

91 +The following functions are available for the Modbus protocol:
92 +
93 +FC5 (0x05) - recording the value of one flag (Force Single Coil).
94 +
95 +FC6 (0x06) - recording the value to Preset Single Register.
96 +
97 +FC16 (0x10) - recording multiple registers, used to record a block of contiguous registers (1 to 123 registers) to a remote device (Write Multiple Registers)
98 +
99 +The** Value lenght** field specifies the number of registers to be recorded.
100 +
101 +The **Switch on address** field specifies the address of the register in the device memory where the enable command will be written. The address should be a non-negative integer.
102 +
103 +The **Switch off address** field specifies the register address in the device memory where the disable command will be written. The address should be a non-negative integer.
104 +
105 +The **Switch on value** and **Switch off value** indicate the value to be written to the register address to execute the disable command. The value can be specified in decimal, binary, octal, or hexadecimal (HEX) format. Decimal is written as a plain number, binary is prefixed with 0b or 0B, represents setting the two least significant bits to 1 and 0, octal is prefixed with 08, HEX is prefixed with 0x or 0X.
106 +
107 +The **Write by bitmask **field specifies the mask in decimal, binary, or HEX format.
108 +
109 +2) The //Control// function is available for Modbus TCP (Modbus RTU over TCP) protocols (see Fig. 3.1.3 ), and OPC DA (see Fig. 3.1.9).
