@cechurat Hi Tomas,

Thanks for replying. With the SRTF block in a fast taks, I try to call a slower task on demand (setting EXDIS: True and manual pulse to EXOSH). This generally works, but the timing is not what we want.
The slower task should be executed at the end of a tick of the fast task right away and not wait for the next tick of the slow task. In other works, we want to start the slow task independent of its ticks and toggled by a manual pulse.

I've shared an example project where one can see that the timing is not what we want. In the project open the TRND bock and run MP. We want the time of the top of the rising edge to match the time in the display; neglecting computation time to calculate the time.

I hope my intention is clear.
Regards
Carvin

I'm a bit confused how to connect blocks where the documentation says "Input reference to a matrix or vector". What do i have to connect there to?
I want to get an array out of a python block and then read it in another task out one by one. As one can see I'm able to extract the array, put at the other side of the outport the array doesn't arrive.
As for reading the array out with one value per tick I thought about the MX_AT block and somehow increase the i by each tick. Any recommendations for that. Is that a good way or are there some blocks which make my life easier?
Thanks!
