9.3.1 Baud rate conversion
Through the use of an optical data transmission system, the bus is divided into two segments. Differ-
ent baud rates can be used in the physically separated segments. The DDLS 200s then function as
baud rate converters. During baud rate conversion, it must be ensured that the bandwidth of the seg-
ment with the lower baud rate is adequate for processing the incoming data.
9.3.2 Sorting (switch S4.1)
With the aid of switch S4.1, sorting of the internal memory can be activated and deactivated. If sorting
is deactivated (switch S4.1 = OFF, default), CAN frames are handled according to the FIFO principle
(First-In-First-Out).
If sorting is active (switch S4.1 = ON), CAN frames are sorted according to their priority. The message
with the highest priority in memory is the next one to be put onto the connected network for arbitration.
