Pavel M Posted May 19, 2020 Report Share Posted May 19, 2020 Hello I'm using V700 with 18E3/4XB and trying to make impulse counter without using high-speed input The problem is, input frequency is about 400Hz. Input pulse is always meander So, the question is: is that possible to make it with 1.25ms interrupt + immediate read physical input? Just put positive transition contact with increment of some integer I was thinking, that with 400hz/s i have circle time 2.5ms, with duty cycle 50% i react on every impulse. So, frequency 400Hz is my maximum without errors Is that possible to create and organize or am i missing something? Quote Link to comment Share on other sites More sharing options...
