CANlink mobile 3000 Device Manual

6.4. File Transfer

You can use the device to transfer files between the DataPlatform and the machine's CAN open network.
6.4.1. Transfer User File via the DataPlatform
Performing controller updates without being physically on-site is an increasingly important application for many OEMs.
This chapter describes how a user file can be transferred from the Proemion DataPlatform via internet and cellular
network to a CANlink mobile and from there to an ECU via CAN Bus.
A common use case for this function could be a parameter update of the ECU. The update file is loaded remotely into
the CANlink mobile and stored within the internal filesystem. An external device can then download the file by using
SDO commands on the CAN bus. The CANlink mobile only acts as a gateway with an integrated CANopen file server.
Please be aware that the transferred files are not checked or controlled in any way by the CANlink mobilee itself. So,
the files must be checked and processed by the target device (ECU).
