  • Page 39: Modbus Information

    100, the BMS-100 firmware needs to be version 3.6 or greater. Introduction: The Modbus interface to the BMS-100 is accomplished via an intermediary processor board, the BMS Combination Card. The function of this board is to serve as a Modbus RTU slave, handling requests from the Modbus master to read information and relay command data to the BMS-100 board.
  • Page 40 Modbus Information Basic Read Operation: Basic operation of the BMS-100 with Modbus is as follows: For reading a register (or registers) the Modbus master sends a holding register read request to the BMS Modbus board using Modbus Function 03 (see “MODBUS APPLICATION PROTOCOL...
