LAN1.LowProt 3 0..2 R
Low level communication protocol. This member represents
the physical and data link layers of the OSI reference model.
The CAN low level protocol features:
Bit wise Contention, mechanism to resolve collisions based on
the priority of the message id number.
# Standard Data and Remote frames, 11 bit id (CAN 2.0 part A).
# Extended Data and Remote frames, 29 bit id (CAN 2.0 part B).
# 12 ”Live” Message objects. (CAN 2.0 part B).
# 0 to 8 byte data per message.
# Programmable bit rate (higher bit rate for shorter distances).
(Note. bit rate is not the same as throughput).
This member is also used to inform an application program
about the presence of the LAN.
0 = Not available
1 = Standard, CAN specification 2.0 part A is supported.
2 = Standard and Extended, CAN specification 2.0 part B is
supported.
The Standard CAN spec is a subset of the Extended spec.
The CAN protocol uses a multi-master (contention based) bus
configuration for transfer of ”communication objects” between
nodes of the network. This multi-master node is also referred
to as CSMA/CR or Carrier Sense, Multiple Access, with
Collision Resolution.
As defined in ISO/DIS 11898 Road vehicles - Interchange of
digital information - Controller area network (CAN) for highspeed
communication.
LAN1.HighProt 4 0 R
High level communication protocol. This member indicate,
what protocol set are used for the layers that are not defined in
LAN.LowProt.0 = No high
level protocol implemented.
