    According to the Modbus standard the Holding Register registers are addressable from 0 to 65535, there are 2 different conventions for numbering the addresses: "0-BASED" and "1-BASED". For greater clarity, Seneca shows its register tables in both conventions. ATTENTION! CAREFULLY READ THE DOCUMENTATION OF THE MODBUS MASTER DEVICE IN ORDER TO UNDERSTAND WHICH OF THE TWO CONVENTIONS THE MANUFACTURER HAS DECIDED TO USE www.seneca.it...

  • Page 13: Bit Convention Within A Modbus Holding Register

    The representation of a 32-bit value in the Modbus Holding Registers is made using 2 consecutive Holding Registers (a Holding Register is a 16-bit register). To obtain the 32-bit value it is therefore necessary to read two consecutive registers: www.seneca.it ALL RIGHTS RESERVED. NO PART OF THIS PUBLICATION MAY Doc. MI00546-EN Rev.2...
