Micrologix1400 pulse rate

Hi Chaps,
Looking for a crude way to capture speed of pulses coming into a digital input, this is not critical as it is only to be used for a speed comparison in my logic.

Max speed around 250 pulses per minute for example.

Set up a one second timer (T4:0). CTU the pulses while the timer is running (T4:0/TT)

OK Thank you, sometimes its a case of can't see the wood for the trees.
