3.5.2.5
Activate Bit Timing Parameters
Activates bit timing parameters selected with
Configure Bit Timing Parameters.
Upon receiving an activate bit timing command, the LSS Slave stops communication on old (actual) bit rate.
After the first switch delay, communication is switched to new bit rate, after a second switch delay, the LSS
Slave is permitted to communicate with new bit rate.

3.5.2.6
Store Configuration Protocol
Stores the communication parameters Node ID, CAN bit rate, and RS232 bit rate in a non-volatile memory.

Inquire Identity Vendor ID
Reads «Vendor ID» of a LSS Slave («Identity object» 0x1018;
EPOS4 Firmware Specification).

switch delay
The duration [ms] of the two periods time to wait until the bit timing parameters switch is
done (first period) and before transmitting any CAN message with the new bit timing
parameters after performing the switch (second period).
