INCA Add-on CAN-Transmit

Overview

Transfer ECU Data from INCA to other SW Applications

− The INCA Add-on CAN-Transmit helps to send out any measured signal from

an INCA experiment via a CAN-Device

− Use any ETAS CAN-HW that supports BOA* for sending

− Recommended HW: ES581.4

− Use Case: Couple INCA with another measurement system

− Send e.g. ETK-signals to the measurement system

− No need for ASAP3, iLinkRT or EtherCAT implementation

− Or reduce load on ASAP3 interface of a test bench system

− Use ASAP3 to only start an INCA experiment remotely

*: ES590/690 and ES1222 are supported but not recommended

Transmit Performance

Performance Measurement

− Measurement configuration with ES592 (ECU access) and ES581.3 (CAN-

Transmit):

− Performance depends on target server cycle time

(setting in INCA options)

− Maximum transfer rate per signal: 10ms

Target Server cycle time Messages Signals Time delay10 ms 10 40 ca. 10 - 30 ms

100 ms 10 40 ca. 20 - 120 ms

INCA Add-on CAN-Transmit

1. Step: Create DBC-File

DBC-Generator: a convenient creation of DBC files from INCA experiment• All measurement signals from the current experiment can be selected for sending• Select transfer rate individually per signal• Define Message-ID and byte-order for the DBC-file

2. Step: Structure of the DBC-File

It is possible to use an own dbc-file, but only frames that are marked as „INCA“ are usedto generate the output channels

3. Step: Assignment of the DBC-File to the CAN-Transmit Device

Hardware configuration:• Select CAN device in HWC• Assign CAN dbc-file• Set parameters:

• Default value• Start message sending• Generate output channel

4. Step: Assign Output Channels

The output channels are assigned in the INCA experiment (manually or automatically)The experiment should first be saved

Generate Output Channel Names from DBC-Comment

The names of dbc-signals are limited to 32 characters, longer names for output channelscan be used if the parameter „Generate output channel from comment“ is set to „Yes“

The generated dbc-file contains the original signal name in the comment section
