please remember the following facts about the high speed puls inputs:
a) The "cnt" pin of the (or a) counter must be direct connected with an input pin - If not, then the maximum rate is only 0.5 * fz (with fz = LOGO! cyclic frequency)b) The output pin to the counter gets only new states at one time every LOGO!- cyclec) A pointer to the counter actual value (inside an analog block) gets only a new value at one time every LOGO!- cycle
That means, that the using of high speed input pulses is verry difficult and for the most applications not good usable - because the LOGO!-cycle frequency is to low, sorry!
