Modbus Registers

The main information needed for remote supervision of a TransferPacT Switching Equipment is contained in the table of common registers starting at register 1001.

One Modbus read request is limited to 125 registers maximum. Three Modbus read requests are necessary to read the entire table.

Use of these common registers is highly recommended to optimize response times and simplify the use of data.

Table Format

Address	Register	Pole number	R/W	Unit	Type	Range	TA	Bit	Description

Address: a 16-bit register address in hexadecimal. The address is the data used in the Modbus frame.
Register: a 16-bit register number in decimal (register = address + 1).
Pole number: number of poles that are applicable for that register.
R/W: register read-write status
- R: the register can be read by using Modbus functions
- W: the register can be written by using Modbus functions
- RW: the register can be read and written by using Modbus functions
- RC: the register can be read by using the command interface
- WC: the register can be written by using the command interface
Unit: the unit the information is expressed in.
Type: the encoding data type (see data type description below).
Range: the permitted values for this variable, usually a subset of what the format allows.
TA: type of TransferPacT switch for which the register is available.
Bit: bit position applicable for that register.
Description: provides information about the register and restrictions that apply.
