A CANopen network usually consists of several devices with different
functionality. One main function is the NMT master which shall exist in
every CANopen network. Its task is to control and monitor the NMT state
of all NMT slaves. Commonly, the CANopen device which controls the
system from an application point of view implements the NMT master also,
e.g. a PLC.
The CANopen Manager according to CiA 302
combines the NMT master with additional functionalities and implements
processes in a standardized way, e.g. the boot-up of the network. This
boot-up consists of the scan for expected CANopen devices and their
configuration by the Configuration Manager.
Furthermore the CANopen Manager may implement the SDO manager which
is responsible for dynamic establishment of SDO connections. This means,
that SDO connections do not have to be configured when installing the
system, but CANopen devices are able to request SDO connections to other
devices at run time. These CANopen devices which are the counterpart of
the SDO manager are called “SDO requesting device”. The SDO manager
ensures that the same SDO server of a CANopen device is not used by two
SDO clients at the same time, if and only if no SDO connections are
established dynamically by CANopen devices themselves.
