Software Updates via USB
STW now offers quick and simple software updates to ESX® controllers via USB.
When USB 1.0 was launched onto the market, with the aim of standardising the interfaces for peripherals on
workstation PCs, it was impossible to conceive what an impact USB would have on industry. USB has proven
itself suitable for a wide range of applications, including mass data storage, printers, scanners, and cameras,
and for the more trivial applications, like the USB powered coffee cup warmers or desktop fan.
Now, for some machine operators, the option of a coffee warmer may be the decisive criterion for the
purchase of this machine, but usually the efficiency and availability of the machine win through. For an
intelligent machine, it should be possible to update the software configuration automatically or, at least, as
simply and quickly as possible, without risk, and with minimum downtime
Sensor-Technik Wiedemann (STW) can now offer the option of updating the control systems of mobile
machines on site, using just a USB stick. Through a newly developed update process, STW is able to offer
customers a new flexibility and independence. Software updates can be downloaded on site, and without an
additional computer or diagnostic system uploaded to the machine. The prerequisite is that the vehicle or
machine is equipped with an ESX®-3Xx with the EB07 expansion board. The EB07 adds the USB to the
standard configuration of the ESX control units. It is equipped with its own 400 MHz CPU and a LINUX Kernel
incl. 1 GByte Data Flash and brings additional communication ports, including RS232/CAN/Ethernet (10/100
Mbit/s).
Before the update process can be performed, the application developer uses the Update Data Generator
software (UDaG) to create an Update Data Package (UDaP). The update generator compiles all the
necessary components (including scripts and programs) for the update package. The update package
contains the updated application-specific program, as well as additional auxiliary files, and an automated
security mechanism. STW supplies the necessary tools to create the data package, and sample code for the
target controller for both C- and CODESYS applications.
As soon as the UDaP is available on the USB stick, it can be connected to with the ESX-3Xx controller, and
the update is performed automatically.
