GENERAL DESCRIPTION
Modbus data is mapped in tables and assigned an address. Data can be of two types:
• REGISTER, 2 bytes (word of 16 bits) that can be associated to an analog input or output, a variable, a setpoint, etc.
• COIL, 1 bit that can be associated to a digital input or output, or to a logic state.
A register could contain the image (mirror) of a group of coils; for example, the digital inputs or outputs of a device could be read or
written as individual bits addressing the coil related to each or can be read or written as a word addressing the register where each bit
corresponds to a coil. Modbus registers and coils are divided into the following groups of addresses:
• 0xxxx and 1xxxx = Coils (bit)
• 3xxxx and 4xxxx = Registers (word)
When reading functions are performed, use the tables indicated below to address the registers. These registers may be addressed by a
Modbus TCP/IP server or by the integrated web server.

NOTES:
• Registers and coils marked as RO in the column 'Access' are Read Only registers.
• Registers and coils marked as R/W in the column 'Access' are Read and Write registers.
• The group of 0xxxx addresses mirrors the group of 1xxxx addresses; the group of 3xxxx addresses mirrors the 4xxxx addresses.
Therefore the first register could be addressed either as 30002 (with function 04) or 40002 ( with function 03).
• A maximum of 128 coils can be read through Modbus function codes 01 and 02 (see "Supported modbus functions codes").
• A maximum of 64 registers can be read through Modbus function codes 03 and 04 (see "Supported modbus functions codes").
• A maximum of 64 registers can be written by Modbus function code 16 (see "Supported modbus functions codes").
• A maximum of 64 coils can be written by Modbus function code 15 (see "Supported modbus functions codes").
