Write to the Discrete Inputs register.


node1.writeDiscreteInput(address, value)
node2.writeDiscreteInput(address, size, buffer)


  • node1/node2: ModbusSlaveNode object.
  • address: The address of the Discrete Inputs registers to write to.
  • value: The value of the single Discrete Inputs register that you want to write to.
  • size: The number of plural Discrete Inputs registers to write to.
  • buffer: Copy the data of the array in the array space pointed to by the buffer to the Discrete Inputs register.


int: If it succeeds, send back MODBUS_SUCCESS, and vice versa send back EXCEPTION_CODE.
