This code can be used to set the baud rate for 2175 modules.
Note!
This code is only effective if the DIP switches S1-S6 have been switched OFF before mains
switching.
A baud rate modification will only become active after power-on of the 2175 module or sending of
the network management command
Reset_node
or
Reset_communication
via the CAN bus.
With 9300 servo PLCs it can also be modified by setting code C2120 (AIF control byte) to 1.
Code L-C1851 maps code L-C0125 of the basic unit, i.e. writing to L-C1851 has a direct effect on
L-C0125.

After power-on, the module sets PRE-OPERATIONAL status. With this status parameter data
(SDOs) can only be exchanged.
In slave operation, the module remains in this status until the network management command
Start_remote_node
is put into OPERATIONAL status.
With OPERATIONAL status, parameter data (SDOs) and process data (PDOs) can be exchanged.
In master operation, the network management command
Start_remote_node
is sent after the
boot-up time set under L-C1856/1 and L-C2356/1). This command puts all nodes into
OPERATIONAL status.
Note:
The network management command
Start_remote_node
is a “broadcast” telegram addressing all
other nodes.
CANopen relation
Bit 30 of the CANopen index 1005
h
“COB-ID SYNC message” has direct influence on this code.
Bit 30 = 1: Master operation
Bit 30 = 0: Slave operation
A modification of this code also changes the CANopen index 1005
