Hi,
I am working on Modbus RTU and ASCII master device implementation. My understanding is that in Modbus protocol Holding register and input register uses 2 bytes for each register is this Modbus standard that every Holding register and input register should use only 2 bytes.
is there any possibility of devices using different sizes (1, 3, 4 etc… bytes) for the Holding register and input register.
another question is Modbus data in Holding register and input register read response will be always in big endian format only...
