Client Sdo (System Bus Master) - BONFIGLIOLI Active Cube User Manual

7.8.4 Client SDO (system bus master)

Each subscriber on the system bus can be addressed via the SDO channels. In this
way, each subscriber can be addressed and parameterized by one master via its
client SDO1. All the parameters of the data types uint/int/long are accessible. String
parameters cannot be processed. If a frequency inverter has been defined as a sys-
tem bus master, each subscriber on the system bus in this frequency inverter can be
addressed by means of a field bus connection (RS232, RS485, Profibus-DP) via its
client SDO1.
Note:
The service used is SDO Segment Protocol Expedited according to CANopen. A fre-
quency inverter defined as a system bus master automatically generates the correct
telegrams. If the SDO channel is operated via a PLC/PC on the system bus, the tele-
grams must be generated according to the specification.

The second SDO channel SDO2 of the frequency inverters is planned for
the parameterization of the frequency inverters via a visualization tool on
the system bus.
