Communication model
34.4.2.2 Communication modes
CANOpen defines multiple communication modes for the input/output data
(PDOs):
Event-driven:
Telegrams are sent out as soon as their content has changed. In this
case not the process image is constantly transferred but only the
changes thereof.
Cyclical, synchronous:
A SYNC telegram triggers the modules to adopt the previously received
output data and to send new input data.
Required:
The modules are triggered to send their input data via a CAN data re-
quest telegram.
The requested communication mode is set via the parameter "Trans-
mission Type".
34.4.2.3 Transmission rates
Transmission rates from 125 kBaud to 1MBaud are available to cater for
the different lengths of the Bus. The effective utilization of the bus band-
width means that CANOpen attains short system reaction times at com-
paratively now data rates.
34.4.3 CANOpen services
The following CANOpen-services are supported (for CanOpen-Slave):
