Using these objects, it is possible to access all
of the parameters in the MICROMASTER
according to the formula MICROMASTER
parameter number in hex + 2000H = SDO
number. In this case, it does not involve
CANopen objects, as the numbering of the
sub-indices differs with respect to CAN-open
(subindex 0 does not contain the number of
objects, but already the first object). However,
the objects from the parameter channel can,
just like CANopen objects, be read and written
using SDO access operations - they are
designated with a * in the following.
U16 /
These objects set the NodeID of the
rw
MICROMASTER.
If this value is changed on the CAN bus it
takes effect after a reset communication or
reset node network command.

These objects directly write process data into
parameters P2050.2, P2050.3 and P2050.5.
The gaps in the sub-indices are due to the
mirroring of the object directly to parameter
P2050 (PZD from CB). All other receive
channels of the P2050 are occupied with the
objects of the device profile. An error message
is output if an attempt is made to map other
sub-indices or to read/write using an SDO.
