  1. Goodmorning, Currently I'm using a cDAQ 9135 shipped with WES7 as OS for a acquisition application. My code is based on the continous acquistion template (event loop, message loop, acquition loop, logging loop and visualization loop) based on data sharing with queues. Now I wanted to extend this code with daqmx writing blocks as I need to add a closed loop control. However I noticed that my acquisition loop is running too slow for a 'realtime' closed loop control. +/- 20 ms/iteration is the best i can get with a timed loop IF disable the visualization loop. Otherwise it goes to 200 ms/iteration. To have a closed loop control I read it would be better to have a real time target. Therefore I would need to change the OS of my cDAQ from WES7 to Linux Labview RT. As I understood, then the acquiring/control and logging would run on the RT target and the visualization on a host computer connected by ethernet or usb to the cDAQ. Now the questions: - Will I get better performance by going to the Labview RT solution? - Is it uberhaupt possible to change from OS on my cdaq? and if yes, how to do this? Thank you in advance. Kind regards, bvrm
