Syntax

set_param_dbc(b,dbcfilename,bo,dir,ioboardtype,boardno,netno,canidformat,importcompatname,splitlongsignals)

Description

set_param_dbc configures the specified instance of the DBC CAN block.

Assumptions:

• No other DBC CAN blocks are open when this function is called.
• The model containing block b is loaded in MATLAB.

Arguments

b

Block name, specified as a string as returned by the gcb command.

dbcfilename

Full path and file name of the .dbc file.

bo

Message information, specified as one of the following:

• Number, specifying the message ID as a decimal number
• String, specifying the message name

dir

RTDB variable direction, specified as one of the following:

• 1 - Input
• 2 - Output

ioboardtype

I/O board type, specified as one of the following:

• 1 - ESD 405
• 2 - IXXAT

boardno

Board number, specified as an integer in the [1,4] range.

netno

Net number, specified as an integer in the [0,3] range.

canidformat

Flag indicating the CAN ID format, specified as one of the following:

• 1 - Decimal Can also be specified using the enumeration: simwb.constants.dbc.canid_dec
• 2 - Hexadecimal Can also be specified using the enumeration: simwb.constants.dbc.canid_hex

importcompatname

Flag indicating whether the RTDB variable name should follow the pattern used by the DBC Import I/O device in the Control Center. Specified as one of the following:

• 0 - RTDB variable name format is: b<BOARDNUM>_n<NETNUM>.id_<CANID>.<SIGNALNAME> Can also be specified using the enumeration: simwb.constants.dbc.importcompatname_exclude_txrx
• 1 - RTDB variable name format is:
  • Output - <TXECU>_<SIGNAL_NAME>_<CANID>_<POINT_TYPE>
  • Input - <sigECUList[rxecucount]><SIGNAL_NAME><CANID><POINT_TYPE>
  Can also be specified using the enumeration: simwb.constants.dbc.importcompatname_include_txrx

splitlongsignals

Flag indicating whether signals that are longer than 32-bits must be split into 1-byte sub-signals, specified as one of the following:

• 0 - Do not split signals longer than 32-bits
• 1 - Split signals longer than 32-bits into 1-byte sub-signals. Signals must satisfy the following criteria to be split:
  • Number of bits is greater than 32
  • Number of bits modulo 8 is 0
  • Signal gain is 1
  • Signal offset is 0

Example:

load_system('simwbCustomBlocklib');
% m is the name of the model 
open_system(m)
b = sprintf('%s/my_blk',m);
add_block('simwbCustomBlocklib/DBC_CAN',b)
dbcfilename = fullfile(pwd,'my_dbc.dbc');
bo_id = 42;
dir = 1;
ioboardtype = 1;
boardno = 1;
netno = 2;
canidformat = 2;
importcompatname = 0;
splitlongsignals = 0;
set_param_dbc(b,dbcfilename,bo_id,dir,ioboardtype,boardno,netno,canidformat,importcompatname,splitlongsignals);
