4.8.4 Client SDO (system bus master)

Each node on the system bus can be addressed via the SDO channels. In this way,

each node can be addressed and parameterized by one master via its client SDO1. All

the parameters of the data types uint/int/lon

are accessible. Strin

parameters cannot

be processed. If a frequency inverter has been defined as a system bus master, each

node 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.

Attention! 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.

The service used is SDO Segment Protocol Expedited according to CANopen. The 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.
