Hello everyone,

Currently puzzled how to convert Int to pulses.

In other words there's a quantity of pulses, say number 16, at output should appear a sequence of 16 pulses, say positive length 250 ms, pause 250ms.

For a better understanding a sketch is attached.

Hi!

Well, as usual, there are multiple solutions.
You obviously need a pulse generator and you have to count the pulses.

You can create a pulse generator or you can use the LGF library.

When it comes to time, I like to use the PLC time. There are nice built-in functions like RD_SYS_T and T_DIFF.

Note: the picture below is not a function from the LGF.

 I am afraid the library you advised has no a block you showed at post above. So, how to count pulses done?

This response would have been an answer if you provided information about the controller and the software (version).

Also: What do you need the pulses for? Hopefully it is not to drive a stepper motor.

No, for step motors there's a separate FB, provided by Siemens I believe.

For initialization of a device i need to perform certain quantity of pulses at its input. So I need something like described above.
