The MA
235i
is assigned an address in the planning tool, which then has to be set in the MA
S1 and S2 address switches. Only if the addresses are the same between the MA
the control can communication be established.
After all parameters have been set in the planning tool/control, the download to the MA
takes place. The set parameters are now stored on the MA 235i.
Afterwards, all MA
retaining the parameters during device exchanges, as they a re now also stored centrally in
the control.
The CANopen baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA
Only if the baud rates are the same is communication with the MA
In a CANopen network, all participants have in principle equal privileges. Each participant
can initiate its data transmission independently. Here, the arbitration specified by the CIA
controls the access of the individual participants to the network. Generally, each CAN partic-
ipant listens in on the bus. The transmission process is started only if the bus is not occupied
by another CAN participant. When transmitting, the current bus status is always compared
to the own transmitted frame.
If several participants start a transmission simultaneously, the arbitration process decides
which participant gains access to the network next. The individual participants are inte-
grated into a prioritization scheme via their bus address and the type of data to be trans-
mitted (index address of the data). Process data (PDOs) of a device are transmitted with a
higher priority than, for example, variable objects (SDOs) of a device.
The node address of the participant is another criterion for prioritizing a participant in the
network. The smaller the node address, the higher the priority of the participant in the
network.
Since every participant compares its own priority with that of the other participants at the
time of bus access, the participants with low priority discontinue their transmission activities
immediately. The participant with the highest priority obtains temporary access to the bus.
The arbitration process controls the access of all participants so that even participants with
a low priority have access to the bus.
