I don't think you can change the OPC update rate at run-time. You can try changing the Update Deadband using the tag attribute from Unclebump's post. But am not sure if this requires an Engine restart.
Maybe what you could do is, to put the Read Tag VIs in different loops and then control the rate of these loops individually, and at run-time.

thanks for the responses,
in this application i don't use read tag.vi because i read the information store in citadel throug datasets (this is the best way to store/read relationship information)
the information is the result of test (measure temperature) then when start the register of the information until stop this register there are days or weeks. if i know that the test is for one hour can set the update time every 60 seconds, for example. but what happen if the test is for weeks and many times in the month, i think (i'm not sure) that slowly the citadel database and my application, for this reason i need change the time of update/save information in citadel. the only way that i find is changing the update time in the tags of my dataset.
regards,
andres
