WEBLOG 250
The WebLog may need firmware updates to solve software issues or add new features from time to time.
The Relay GmbH supplies firmware updates with image files of about 50 MByte size for download from our
homepage:
(
http://www.relay.de/de/produkte/m-bus-master/weblog-250.html).
You will have to ask us for a user name and a password to be able to access that files.
The first step is to copy the image file to an empty USB memory stick. Then please connect the USB stick to
the USB master jack in the front of the Weblog device.
A click on the button “System Update” shows the content of the connected USB stick.
Please push or click on the filename of the update image. The update is started after the administrator has
confirmed the safety query. The update file is automatically copied from the USB stick to the internal SD card
and the software sets a notification for a pending update in the bootloader. After an automatic restart of the
system the bootloader detects the notification and starts a minimal rescue system used to flash the new
firmware image. The flash procedure takes some minutes. A progress bar on the touch screen of the WebLog
shows the current status of the update procedure. The device will automatically restart the system after
finishing the flash process. The user is then requested to calibrate the touch screen. After calibration the login
screen of the application appears.
In case of the seldom event that the WebLog is no longer operable you can press the reset button on the left
side in the terminal area to force a restart of the system. If the application does not start correctly because of
a corrupted flash content, you can use an alternative flash method: Please press the reset button minimum
