<strong>CANopen</strong> <strong>Basics</strong><br />
<strong>CANopen</strong> provides two mechanisms to ensure that the<br />
bus stations are fully functional.<br />
This mechanism is controlled by the NMT master to cyclically<br />
check if the NMT slaves are still able to communicate.<br />
It involves the NMT master sending out messages to<br />
the NMT slaves that the slaves must respond to by returning<br />
their communication status within the set timeout. This<br />
enables the NMT master to realise if a unit fails. On the<br />
other hand, a NMT slave realises if the NMT master has<br />
not requested its devices status for longer than its Life<br />
Time.<br />
