Thank you for your kind response to the post. Actually, the shaft speed is between 3250 and 2750. Yes sir, i am looking for a a self-resetting timer to copy the value out of a Counter accumulator every X number of seconds. Actually iam not sure that the controller can track the 1500 pulses per second. Can you plz show me the ladder diagram for the above application (suppose the controller can handle it).

Dear guys, If anyone knows how to make ladder diagram for measuring speed (RPM) of a rotating shaft (turbine). Here, a magnetic pickup pulse is connected nearby the shaft and , which gives i/p s to the pulse to the PLC. (Suppose, 25 pulse means one rotation ). So, guys pls post here the ladder logic diagram for the above application.
