(8.D.2.7) SinkIntProperties

Overview

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

Discussion

This module copies the integer 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.

To temporarily pause the copying, place the module into the INACTIVE state.

Additionally, this module makes the wire information available as internal variables. Block size, channel number, sample rate and signal complexity can be accessed in MATLAB code, source code, or in a layout using the ParamGet module.
