DVP-ES3 Series Programming Manual _6 Symbol S 1 ： Baud Rate (Unit:100 bps) S 2 ： Number of data bits S 3 ： Parity bit S 4 ： Number of end bits S 5 ： Modbus format selection D ： Communication port number Explanation 1. This instruction provides a way to directly set the parameter values, instead of declaring variables. 2. S 1 sets the baud rate with the units 100 bps. For example, a value 96 indicates 9600 bps. 3. S 2 sets the number of data bits. The value 7 indicates 7 data bits and 8 indicates 8 data bits. If the value is not 7 or 8 in S 2 , the instruction uses the default value.
