Is there a PLC command that supports two variable speeds for continuous pulse output control?
Yes, the PLC's "DDRVI" command with the flag "M1119" together can output two variable speeds of continuous pulses. Simply input two sets of frequency and output pulse numbers into the corresponding data register of "DDRVI" and set the flag "M1119" to ON. You will now get a two variable speed continuous pulse output as shown in the figure below. (Note: this function is available for the PLC models DVP28SV with firmware version 2.0 and the higher level models.)
