I can make something similar by playing with timers, but wonder if there are any blocks from standard library? Thanks

But this block is not standerd one from siemens library, I have created this block. Note: From this block you can generate pulses more than one second only. Less than one second is not possible.

Ineedto record some process changes and would like to have pulse train as input signal for excitation of a process. I can make it by playing with S5 timers, but wonderedif there is already something standard for this purpose. Time period would be about 30-60s but it is not time critical (precise). Thank you all for your feedback

In CFC or PCS7 library it's AFP block. The chapter 1.14.15 in here: http://support.automation.siemens.com/WW/view/en/24451026 Regards Sydney
