SD card
An SD memory card (short for
S
ecure
D
igital Memory Card) is a digital storage medium that operates
to the principle of
→flash storage.

SDO
SDO =

ata
O
bject.
The SDO is used for access to objects in the CANopen object directory. 'Clients' ask for the requested
data from 'servers'. The SDOs always consist of 8 bytes.
Examples:
• Automatic configuration of all slaves via
→SDOs at the system start,
• reading error messages from the
→object directory.
Every SDO is monitored for a response and repeated if the slave does not respond within the
monitoring time.

Self-test
Test program that actively tests components or devices. The program is started by the user and takes
a certain time. The result is a test protocol (log file) which shows what was tested and if the result is
positive or negative.
>
Slave
Passive participant on the bus, only replies on request of the
→master. Slaves have a clearly defined
and unique
→address in the bus.
>
stopped
Operating status of a CANopen participant. In this mode only
→NMT commands are transferred.
>
Symbols
Pictograms are figurative symbols which convey information by a simplified graphic representation.
