Path in the library: |
Description
Block CAN Pack loads the signal data into the CAN message at specified intervals during the simulation.
Ports
Output
#
CAN Msg
—
output CAN message
bus
Details
This unit has one output port: CAN Msg. Block CAN Pack accepts the specified input signals and packages them into a CAN message.

Data
—
input signal for CAN message
vector
Details
Block CAN Pack It has one input port by default. The number of input ports of the block is dynamic and depends on the number of signals specified for the block. For example, if the message contains four signals, then the block may have four input ports.
The unit supports all data types of input signals.

Parameters
Main
#
Data is input as —
select the data signal
raw data | CANdb specified signals
Details
-
raw data— input data in the form of a vectorUInt8. When this option is selected, the message parameters are specified. This option opens only one input port Data.The conversion formula:
where — the initial value of the signal, and — the value of the packed signal.
-
CANdb specified signals— the message parameters are set in a dbc file, which must be specified in the parameter CANdb file. After uploading the file, the parameter appears in the block parameters Message list, which contains a list with all the messages specified in the file and corresponding to the CAN standard (CAN and CAN-FD messages can be stored in one file).After selecting a message from the list, all other fields of the block parameters are automatically filled in. These fields are read-only.

#
Message list —
the list of messages in the dbc file
String
Details
The list of messages in the dbc file that comply with the CAN standard.
Dependencies
To use this parameter, set for the parameter Data is input as meaning CANdb specified signals.

#
Name —
name of the CAN message
String
Details
Specify the name of the CAN message.
This option is available if for the parameter Data is input as value selected raw data. If for the parameter Data is input as value selected CANdb specified signals, then this parameter is read-only.

#
Identifier type —
the type of the CAN message identifier
Standard (11-bit identifier) | Extended (29-bit identifier)
Details
Specify whether the CAN message identifier is standard or extended. By default, the standard type is used. The standard identifier is an 11-bit identifier, while the extended identifier is a 29-bit identifier.
This option is available if for the parameter Data is input as value selected raw data. If for the parameter Data is input as value selected CANdb specified signals, then this parameter is read-only.

#
CAN Identifier —
ID of the CAN message
Real number
Details
Specify the ID of the CAN message. This number must be a positive integer from 0 before 2047 for the standard identifier and from 0 before 536870911 for the extended identifier.
This option is available if for the parameter Data is input as value selected raw data.

#
Length (bytes) —
length of the CAN message
Real number
Details
Specify the length of the CAN message from 0 before 8 bytes.
This option is available if for the parameter Data is input as value selected raw data. If for the parameter Data is input as value selected CANdb specified signals, then this parameter is read-only.
