creating a pulse train with variable length


Recommended Posts

Sure you can, but timers only have a resolution of 10ms. Just multiply your MI by 100 and use "Store Timer/Counter Preset" for the TD timer you wish to use. Make the timer self-resetting (timer activated by inverted contact of the timer) then have a positive transition of the timer activate a toggle coil of the MB you wish to use for the pulse train.

 

If this isn't clear, I'll post a screen capture of the logic - just let me know.

Remember, you must use increments of 10ms. You cannot have a 12ms timer.

HI Flex & Jordy.  I respectfully disagree with the 10ms statement, which although correct implies there is no other way of doing it.  Have a look at this post and the rest of the thread, and play with things readily available: 

With enhanced stuff it can be 1.25ms, which can perhaps better fine tune things to what you need.

cheers,

Aus
