I have some questions for modbus protocol.(rtu format)
- What are the start and stop bits for each byte that have to be appended?(modbus documentation does not mention this)
- Do all the bytes that have to be transmitted(namely-address byte,function byte,data bytes and crc bytes) have start,stop & parity bits?
- Is the baud rate for a particular network in modbus fixed?(9600 or 19200)
- What is the difference between coil and register in modbus terminology?
