Description
CANOPEN_ENABLE allows to switch the CANopen master on or off.
► In the application program always call an own instance of the FB
(→ page 93) for every CAN interface!
To avoid guarding or heartbeat errors the nodes must be "shut down" via an appropriate sequence

If the master is restarted after a stop, all other connected nodes also have to be re-initialised.
Without CANOPEN_ENABLE, the CANopen master is started automatically, as far as this has been
selected in the configuration.
The configured baud rate is only adopted if
