VAN telecontrol profile approach.<br />

The profile uses the functions provided by the <strong>communication</strong> stack. In order to enable <strong>communication</strong><br />

relations via a temporarily unavailable network path, extensions within the <strong>communication</strong> stack<br />

may be necessary.<br />

By the TC profile, the integration of TC functionality into fieldbus technologies has been done, which<br />

starts the merging of both classically separated fields.<br />
