RedLotus Posted June 28, 2011 Report Share Posted June 28, 2011 Hi, I am trying to develop an application that pulses an output relay at a maximum rate of 120 pulses Per Minute (i.e 2 pulses per second). The pulse rate is proportional to a variable value contained in an MI. While it is possible to pulse the output relay at a rate of 60 Pulses per minute using the SB 3 System bit, I was not able to figure out a way to pulse the relay in a two second interval or a half second interval. I would very much appreciate it if anyone could provide any ideas how to go about this one. Thank you very much. Best Regards, JM Quote Link to comment Share on other sites More sharing options...
Ofir Posted June 29, 2011 Report Share Posted June 29, 2011 Hi, You can use a timer for controling the rate of the pulses. Each time you can change the timer preset according to the required rate. Connect inverted contact of a timer to a coil of the same timer. This will create a pulse generator according to the timer preset. Then use a direct contact of the timer to activate your output.
