9.2.1.3 Protocol 6003 (LS-5 Communication)
General information
The LS-5 communication message contains all data, which is required to operate the LS-5
system. This communication protocol works parallel to the load share communication.
In order to lower the bus load, the messages are divided into "fast", "normal", and "slow"
refreshed data. The mux is identied accordingly with "F", "N", and "S" (refer to the
following tables). The load share message contains one fast, two normal, and four slow
messages, which are made up as in ╚═▷ “Load share bus communication”.
Timing
The time interval between two fast messages (TFast , i.e. the time for refreshing a fast
message) is congured with the parameter "Transfer rate LS fast message"
(parameter 9921). The time intervals between refreshing a normal or slow messages
depend on this parameter as well according to the following sequence:
• S0 – F – N0 – F – N1 – F – S1 – F – N0 – F – N1 – F – S2 – F – N0 – F – N1 – F – S3 – F –
N0 – F – N1 – F
• T
Fast
= time interval between refreshing the fast message
• T
Normal
= time interval between refreshing a normal message = 3 x TFast
• T
Slow
= time interval between refreshing a slow message = 12 x TFast
Example
Example
• The parameter "Transfer rate LS fast message" (parameter 9921) is congured to
"0.10 s".
• The sequence of the sent messages for TFast = 100 ms (i.e. 0.10 s) is shown in ╚═▷
“Load share bus communication”.
• This means that a new message is sent every 50 ms.
