12.4 Protocol Description
12.4.1 Definition of inter-frame and intra-frame time interval
A complete MODBUS message contains not only the necessary data units, but also the
starting and ending tags. Thus, as shown in Fig. 0-1 or Fig. 0-3, the idle level with a
transmission time of 3.5 characters or more is defined as the starting and ending tag. If
there is an idle level with a transmission time of more than 1.5 characters during message
transmission, the transmission will be deemed exceptional.
Specific starting/ending and exception intervals are related to the baud rate, as detailed
in Table 0-5. If the baud rate is 9,600bps and the sampling period is 1ms, the starting and
ending time interval is the idle level of 4ms or more (3.5×10/9600=3.64≈4), and the
exceptional data interval is the idle level in which the interval of data bits of one frame is
greater than or equal to 2ms (1.5×10/9600=1.56≈2) and less than 4m (the idle level of
normal data bits is less than or equal to 1ms).

greater, it indicates the end of a frame of data.
