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).

120 +
121 +The position of the **Write values** switch determines whether value write commands can be sent to the device at the specified address.
122 +
123 +The **Function** field selects the Modbus recording function from the drop-down list (see Fig. 3.1.5).

132 +
133 +The **Address** field specifies the address of the tag in the device memory to which the value will be written. The address should be a non-negative integer in decimal format.
134 +
135 +The field **Byte order** from the drop-down list (see Fig. 3.1.6) is used to select different order of bytes and/or words in the written CENTO data.
