Two timeouts in MODBUS: 1. The timeout between two frames is 3.5 characters. 2. The timeout of each character in a frame of data is 1.5 characters Processing a character in MODBUS is equivalent to processing a frame through serial port. The timeout is calculated according to the baud rate of communication: BPS = bit […]
