CANopen information
3.9.4.3 Activate bit timing parameters protocol
The given protocol has implemented the Activate bit timing parameters
service. The protocol activates the Baud rate which was configured about the
Configure bit timing parameters protocol and is performed with all LSS
slaves in the network which are in the state LSS configuration.

Switch Delay
The parameter Switch Delay defines the length of two delay periods (D1, D2)
with equal length. These are necessary to avoid operating the bus with differing
Baud rate parameters.
After the time D1 and an individual processing duration, the switching internally in
the LSS slave is performed. After the time D2 the LSS slave responses with CAN-
messages and the new configured Baud rate.
It is necessary:
Switch Delay > longest occurring processing duration of a LSS slave
3.9.4.4 Store configuration protocol
The given protocol has implemented the Store configuration service. By
means of the LSS master the configured parameters of a single LSS slave in the
network can be stored into the non-volatile memory. Only one device is to be switched
into LSS configuration state. When the protocol is executed the LSS slave will be
reset, an emergency with COB-ID 0x80 + Node-ID and error code 0x00FF 00FF is
transmitted. The LSS slave is switched into PRE-OPERATIONAL state.
