¨ RSP þ PS transfer ¨ CANopen:
The baud rate over the CAN bus can be set using this code.
Changes to the setting are applied after:
ƒ Reconnection to the mains
ƒ A "reset node" command via the bus system
ƒ A reset node using the code C0358
Prior to accessing the CAN bus, the baud rate used is determined by the communication
module and compared with the baud rate configured.
If the two values are different, the baud rate determined is used. The baud rate detected
by the communication module can be read using code C1209.
If there is no data traffic on the CAN bus, the baud rate cannot be determined. The
subsequent behaviour of the communication module depends on the selection configured
in code C0351:
ƒ Selection 0 ... 5
After a time−out that can be configured using code C1215, the CAN bus is accessed
with the baud rate configured.
ƒ Selection 16 (automatic detection of the baud rate)
The communication module does not access the bus until a baud rate can be
detected.
