I have a slave device which supports writing 150 registers at once which is around 300 bytes. I have framed a modbus request which is greater than 300 bytes including slave ID, function code, register start address, number of registers, number of bytes, data and CRC and sent it to the modbus slave device using standard modbus master template code. In standard documentations it is mentioned that the modbus can support writing multiple registers of 123 registers at once. Is there any way to that can support the bulk and huge payload of writing multiple registers?
