V.2 Principle
The Bi-CAN I/O gateway converts digital, Analog, frequency or CAN inputs to digital,
Analog, PWM or CAN outputs. This conversion is performed by means of internal variables
which apply a transfer function to the input values.
The operation of the Bi-CAN I/O gateway is based on three types of variables that can be
modified with a tool using CCP protocol (CAN Calibration Protocol).
These variables are described with PC software, using databases in ASAP2 format. The three
types of variables are as follows:
•
input variables which are a copy of the input information (voltage, logical status,
frequency or value of a CAN signal);
•
internal variables which create a value from an input value and a transfer function;
•
output variables which give the status of physical outputs or CAN signals, using the
values calculated by the internal variables.

V.2.1 Input variables
V.2.1.1 Analog input variables
There are 8 Analog input variables (one for each input). Only the input voltage range can be
parameterised, e.g.: either " 0/10 V ANA input" or " 0/50 V ANA input".
The index of Analog inputs is between 0 and 7.
V.2.1.2 Logical input variables
There are 8 logical input variables (one for each input). Only the input voltage range can be
parameterised, e.g.: either "0 / 5 V input" or "0 / +Battery input".
The index of Analog inputs is between 0 and 7.
V.2.1.3 Frequency input variables
There are 4 frequency input variables. An operating mode parameter can be modified. At
present, this parameter is not taken into account and the frequency inputs operate as frequency
inputs only.
The index of frequency inputs is between 0 and 3.
V.2.1.4 CAN input variables
There are 64 CAN input variables. The index of CAN input variables is between 0 and 63.
Each variable contains 7 parameters, as follows:
•

information is recovered,
•
« Identifier_signal_entree_CAN_x » : Identifier of the frame in which the information is
recovered,
•

available :
•
Intel : Classic Intel format.
•
Motorola for ascendanding compatibility: the same numbering way as in old version
of software (until version 1.4).
•
Motorola : Classic Motorola format.
Remark:
1. The bits are numbered as follows :

•
Position : bit 0.
•
Size : 16 bits.
The Signal 2 can not be defined in the old version of the gateway software so with the
MOTOROLA_COMPATIBILITE_ASC.
4. In Intel format, the Signal 1 will be defined as follows :
•
Position : bit 0.
•
Size : 16 bits.
And the Signal 3 as follows :
•
Position : bit 54.
•
Size : 7 bits.
V.2.2 Internal variables
There are 128 internal variables (index 0 to 127). These variables can be used to perform
operations on the inputs and generate values for the outputs. Each variable contains 11
parameters which can be used to define the operation to be performed and as from which
input or inputs.
•
« Choix_type_entrée_1_Variable_x » : Type of first input variable used. The possible
values are « Variable interne », « Entrée logique », « Entrée analogique », « Entrée
fréquence », « Entrée signal CAN » and « Pas utilisée » ("Internal variable", "Logical
input", "Analog input", "Frequency input", "CAN signal input" and "Not used").
•
« Signal_Entrée_X1_Variable_x »: Index
« Choix_type_entrée_1_Variable_x ».
•
« Choix_type_entrée_2_Variable_x » : Type of second input variable used. The only
possible values are « Variable interne » or « Pas utilisee ».

Bi-CAN I/O gateway - User's Guide
•
« Signal_Entrée_X2_Variable_x » : Index of input 2 among inputs of type
« Choix_type_entrée_2_Variable_x ».
•
« Choix_de_calcul_Variable_x » : Type of calculation to be performed. The following
calculations are available:
•
« Variable = aX + b en long »,
•
« Variable = aX2 + bX + c en long »,
•
« Variable = (aX + b) / (cX +d) en long »,
•
« Variable = aX + b en float »,
•
« Variable = aX2+ bX + c en float »,
•
« Variable = (aX + b) / (cX +d) en float,
•
« Variable = aX1 + bX2 en long »,
•
« Variable = aX1 + bX2 en float ».
The last two calculations allow combinations between several inputs. The second variable
(X2) must be configured as an internal variable. It cannot be an input variable in any
circumstances.
For example, if two voltages have to be added, three internal variables will be required: two to
recover the voltages in the two input variables (each being a transfer function) and one to add
the two voltages.
If X is a variable using an analog input, the corresponding unit is Volt. If it is a variable using
a frequency input, the unit is Hertz.
Using “long” functions allows to convert a decimal result (float) into an integer.
Remark:
Due to processing time requirements, the depth of calculations of internal variables is limited
to 3. It is impossible to perform an operation of the type "aX1 + bX2" with the internal
variable X2 using a calculation of type "aX3 + bX4".
•
« COEF_A_VARIABLE_x » : Value of coefficient "a" for the various types of
calculation. (Must always be configured).
•
« COEF_B_VARIABLE_x » : Value of coefficient "b" for the various types of
calculation. (Must always be configured).
•
« COEF_C_VARIABLE_x » : Value of coefficient "c" for the various types of
calculation. (Must be configured for some operations).
•
« COEF_D_VARIABLE_x » : Value of coefficient "d" for the various types of
calculation. (Must be configured for some operations).
•
« Valeur_Max_Variable_x » : Upper limit for the internal variable. The result will be
limited to this maximum if the calculated value exceeds it.
•
« Valeur_Min_Variable_x » : Lower limit for the internal variable. The result will be
limited to this minimum if the calculated value is lower.

Remark: Coefficients and limits are always expressed as floating-point values. The Bi-CAN
I/O gateway may or may not convert them according to whether the calculation is performed
in integer mode or floating point mode (decimal).
V.2.3 Output variables
V.2.3.1 Analog output variables
There are 8 Analog output variables (one for each output). The following two parameters can
be set:
•
« Mode_sortie_ANA_x » : parameter not processed,
•
« Variable_pilotage_ANA_x » : Index of internal variable associated with the output.
V.2.3.2 High-side logical output variables
There are 8 high-side logical output variables (one for each output). Only the corresponding
internal variable can be configured with the « Variable_sortie_logique_HS_x». parameter.
The level of the logical output will be defined by the parity of the value of the associated
internal variable (less significant bit):
•
Even
Æ
Low level (0),
•
Odd
Æ
High level (1).
V.2.3.3 Low-side logical output variables
There are 8 low-side logical output variables (one for each output). The following parameters
can be set:

•
« Variable_sortie_logique_LS_x » : Index of the internal variable associated with the
output.
•
« Rapport_cyclique_LS_x » : Duty cycle of the low-side output if configured as PWM.
The value of the associated internal variable will be interpreted as the frequency of the
PWM signal.
If the PWM parameter is active and has been set, the value of the internal variable will be
interpreted as the frequency of the PWM low-side output. The duty factor will be as defined
by the « Rapport_cyclique_LS_x » parameter.
If the PWM parameter is inactive or has not been set, the level of the logical output will be
defined by the parity of the value of the associated internal variable:
•
Even
Æ
Low level,
•
Odd
Æ
High level.

V.2.3.4 CAN output variables
There are 64 CAN output variables. A variable of this type contains an index on an internal
variable and information defining a CAN signal: ident, transmission channel, position, size,
etc..
A CAN output variable does not imply that the frame defined in the CAN output variable will
be transmitted but that if the frame defined in the output variable (same transmission channel
and same identifier) is transmitted, then the information contained in the output variable will
be included in the frame's data field.
CAN output variables are applicable to all types of transmitted frames (periodic and gateway).
Each variable contains 6 parameters, as follows:
•
« Reseau_signal_sortie_CAN_x » : Channel number of the frame in which the value of
the output variable is to be included.
•
« Identifier_signal_sortie_CAN_x » : Identifier of the frame in which the information is to
be sent.
•
« Position_signal_ sortie _CAN_x » : Position (in bits) of the information.
•
« Longueur_signal_sortie_CAN_x » : Length (in bits) of the information.
•
« Codage_signal_sortie_CAN_x » : Type of information encoding. Three formats are
available :
•
•
Intel : Classic Intel format.
•
Motorola for ascendanding compatibility: the same numbering way as in old version
of software (until version 1.4).
•
Motorola : Classic Motorola format.
« Variable_Sortie_CAN_x » : Index of the internal variable associated with the output.
V.2.4 CAN gateway
The Bi-CAN I/O unit can provide a CAN gateway between two CAN networks. The frame
retransmission time is less than 2 ms.
The two CAN channels can be set to different baud rates. The following configurations are
possible:
•
Transfer a frame from one CAN channel to another with the same identifier,
•
Transfer a frame from one CAN channel to another with a different identifier,
•
Transfer a frame from one CAN channel to another with a data field of different length,
•
Modify the contents of a frame by using CAN output variables,
•
Transmit a frame on the same channel on receiving a given identifier.
It is possible to configure up to 16 gateway frames. The following parameters can be set:
- 16 -
DUT-MUX-0199E /V1.13
September 2006
Bi-CAN I/O gateway - User's Guide
•
« Canal_CAN_Reception_x » : Channel on which the source frame is received.
•
« IDentifier_Rx_x » : Identifier of source frame.
•
« Canal_CAN_transmission_x » : Channel on which the target frame is transmitted.
•
« IDentifier_Tx_x » : Identifier of the target frame.
•
« DLC_Tx_x » : Size of target frame data field.
V.2.5 Transmission of periodic frames
The Bi-CAN I/O unit can transmit up to 16 periodic frames. The minimum period is 5 ms.
The data fields of frames are made up using the corresponding CAN output variables. If no
variable is linked to a frame, the data field will be null.
5 parameters are required to configure a periodic frame, as follows:
•
« Canal_Trame_CAN_x » : CAN channel on which the frame is transmitted,
•
« DLC_trame_CAN_transmission_x » : DLC of the frame to be transmitted,
•
« Format_Trame_CAN_x » : Format of the identifier (standard or extended),
•
« Identifier_Trame_CAN_x » : Identifier of the frame to be transmitted,
•
« Periode_trame_CAN_transmission_x » : Frame transmission period ( ≥ 5 ms).
V.2.6 Setting the CAN channel baud rate
Two parameters are used to configure the baud rates of high-speed CAN channel 0 (CAN1)
and high-speed CAN channel 1 (CAN2) respectively. These parameters are as follows:
•
« Vitesse_CAN_Canal_0 » : Baud rate of CAN1,
•
« Vitesse_CAN_Canal_1 » : Baud rate of CAN2.
The available baud rates are 250 and 500 kbit/s.
The available baud rates are 250 and 500 kbit/s, until version 1.8 of firmware and version 3.0
of a2L file.
With creation of a Bi-CAN I/O which CAN2 is Low-speed, some baudrates have been added :
10, 20 , 33.33, 50, 83.33, 95.238, 100, 125.
The baudrate High - speed 1Mbits/s has also been added.

VI. Updating and setup
VI.1 Description
The Bi-CAN I/O gateway can be configured by any software handling ASAP2 type databases
and using the CCP 2.1 protocol for calibration. At present, parameters can be set with the
following software: DataMUX, Vector CANapé and ETAS Inca PC 5.2.
VI.2 Files required
The files required for setup and downloading are:
•
The ASAP2 database (.a2l files): there are two a2l files, one for DataMUX & CANape
and one for INCA PC 3.2.
•
A memory map file (.mps file): required for CANape.
•
The application's compiled code (.s file): used only with DataMUX or CANape to update
the application.
•
A reference data set (.hex file): required to set up INCA PC 5.2.
The files are obtained by decompressing the self-extracting archive contained on the CD
supplied with the Bi-CAN I/O gateway.
VI.3 Wiring
VI.3.1 Connection
Connection between a NSI CAN interface, a Vector CANcardX or an ETAS ES690.1 unit and
the Bi-CAN I/O gateway is made using two DB9 connectors. The following connections must
be made:

In both cases, in a High-speed network, don’t forget to add 60Ω terminal resistors on cable
end between CAN H and CAN L.
Remark: When wiring the Bi-CAN I/O gateway in an existing high-speed network, this
terminal resistor must not be added.
VI.3.2 Parameter setting
When using DataMUX, simply follow the wizard instructions.
For the other tools, the process is as follows :
•
•
In order to start the Bi-CAN I/O gateway in parameter setting mode (to modify its setup
parameters), the following operations must be performed:
•
Disconnect the unit's power supply.
•
Tie the "/PROG" signal (pin 10 on the 14-pin connector) to the ground.
•
Power on to the unit (with the short-circuit maintained).
After this operation, the unit switches to parameters setting mode and the red indicator
lamp stays on. It is then possible to start a setup phase with CANape or INCA PC 5.2.

VI.5.2 Updating the application
VI.5.2.1 Forced downloading
Downloading of the application can be forced by the reception of a CAN frame transmitted in
padding mode (by CANalyzer, for example). The frame parameters are as follows:
•
Baud rate :
•
CAN channel : 1
•
Ident :
0xfe (Standard)
•
Period :
1 ms
•
DLC :
8
• Data :
0x30
0x12
1,000 kbit/s
0x00
0x00
0x00
0x00
0x00
This frame must be received as soon as the unit is switched on. When this frame has been
received, the unit switches to CAN download standby mode (CCP protocol) and the red
indicator lamp flashes slowly. When the unit is in this state, cut off the transmission of the
frame while leaving the Bi-CAN I/O gateway powered on and switch to CANapé.
Remark: Only switch the unit on after having started the periodic transmission of the forcing
frame.

VI.6 Using INCA
configuration
V5.2
(ETAS)
for
the
Bi-CAN
I/O
To configure the Bi-CAN I/O Gateway, you have to install the software INCA PC© which
installation program is on the ETAS CD-ROM. This software is not supplied with the BiCAN I/O and its license protected.
Some people may have used INCA PC for other tasks like calibration or tuning and should
have already installed it. For the other ones, please refer to the installation manual delivered
with the CD.
VI.6.1 Installing Files for the configuration of the Bi-CAN I/O
Extract files from the archiv « config_INCA_BicanIO.zip » in a directory.
As default, we advice to use the directory « export » created during the installation of INCA
PC. For exemple : « D:\ETASData\INCA5.2\export »
The file extracted is from the type « export » ( *.exp ) : We will import it in INCA to access
the different files it is made of (menu « Edition/import »).

DUT-MUX-0199E /V1.13

Bi-CAN I/O gateway - User's Guide
Here is a description of the different types of files :
the “experimentations” are some pre-defined windows, where you can display and
modify some parameters and variables of the *.a2l files (tables, variables, etc…).
the “projects” are made of one *.a2l file (this file describes the memory mapping
for the different parameters in the ECU) and one *.hex file containing the values of those
parameters and sometime the software.
in the “workspaces”, you can choose the hardware configuration you will use (for
us, either the OFFLINE mode: no Hardware connected, or the ONLINE mode: we will use
for example a PCMCIA card and the CCP communication), the project which parameters
have to be modified and the experimentation you will see to reach those parameters.
VI.6.2 Import new datasets / *.hex files
The values of the parameters of the Bi-CAN I/O are contained in the *.hex file; the *.a2l file
(linked with the software Version of the Bi-CAN I/O) describes the memory mapping of the
Bi-CAN I/O. It means that *a2l and *.hex files have to be compatible. In an other case
modified values should be written in the wrong space (wrong memory Adress) and the
software won’t work correctly.
In the INCA Software, this association of files *.a2l / *.hex is called project (green Icon)
.
To open a new project : right click, then « Add / ECU project (A2L) » in the left window “1
elements” of the main window of INCA PC. In this example a configuration and a project are
already given.

But a project may accept several datasets if they are all compatible with the .a2l file defined
during the opening of the project.
So in the right window « 4 elements » of the main window of INCA PC, you may add
datasets in two ways:
