Overview

Copies the data at the input pin and stores it in an internal buffer.

Discussion

This module copies the data at the input pin to an internal buffer (value). The copy operation occurs at each block process and thus the data continuously updates. This module is used to store the value of a wire and make it available to the control code, or a host processor. The inspector window shows the data using a plot. In the inspector window, there are two edit boxes for maximum(Ymax) and minimum(Ymin) limits for plotting amplitude. If user gives Ymax less than Ymin then the range [Ymax Ymin] will be automatically set by MATLAB
