changing timed loop time period

Hi,

I am using all the DAQmx feature for material strain data acquisition. Before, I was using a timed loop for data reading processing (DAQmx writing Analog 2D DBL Nsamp Nchan, graphic writing, etc), but i figured out from NI forum and tutorials that using a "timed loop" was more appropriate for avoiding precision issues (no time unconsistency). The problem now is that while my program is working, it doesn't seem possible to modify the period of the timed loop during execution...

Is there a way to modify the timed loop's period (dt) while it is running? If yes, what is it please (what are they)? If not, what other mean or with kind of loop and associated wirings can I use (as precise as timed loop) in order to read my strain datas?

Ok, sorry about that: you simply need to wire in a control on the "dt" parameter of right node of the frame but it wasnt so obvious to find out...  LabVIEW speaking:

at the '(3) Right Data Node' table
