5.1.1.

 

MODBUS ADDRESSES WITH "0-BASED" CONVENTION 

 

The numbering is: 

 

HOLDING REGISTER MODBUS 

ADDRESS (OFFSET) 

MEANING 

FIRST REGISTER 

SECOND REGISTER 

THIRD REGISTER 

FOURTH REGISTER 

FIFTH REGISTER 

 

Therefore the first register is at address 0. 

In the following tables, this convention is indicated with 

“ADDRESS OFFSET”.

 

 

5.1.2.

 

MODBUS ADDRESSES WITH "1 BASED" CONVENTION (STANDARD) 

 

The numbering is that established by the Modbus consortium and is of the type: 

 

HOLDING REGISTER MODBUS 

ADDRESS 4x 

MEANING 

40001 

FIRST REGISTER 

40002 

SECOND REGISTER 

40003 

THIRD REGISTER 

40004 

FOURTH REGISTER 

40005 

FIFTH REGISTER 

 

In the following tables this convention is indicated with 

“ADDRESS 4x”

 since a 4 is added to the address so 

that the first Modbus register is 40001. 

 

A further convention is also possible where the number 4 is omitted in front of the register address: 

 

HOLDING MODBUS ADDRESS 

WITHOUT 4x  

MEANING 

FIRST REGISTER 

SECOND REGISTER 

THIRD REGISTER 

FOURTH REGISTER 

FIFTH REGISTER
