Hi Peter, thanks for your comment. There is no DAQ-card involved. We use a MXI-VXI Subsystem for our data acquisition. Unfortunately I can not localize the error. There are many VIs in use. A lot of them make use of the the "replace array subset" function. Labview doesn't report the VI's name. The applictation is created with the Application builder. I could not catch the error with the LV development environment. Regards Gerhard Finger Nutronik GmbH
