†Problems with ﬁles being corrupted, ﬁles disappearing and the like can be diagnosed with the “Flash test”.

†Overall responsiveness of the system can be veriﬁed with the “LED’s test”.

†Seemingly inexplicable behavior can be caused by defective RAM. The two RAM tests “RAM test 1” and “RAM test 2” cover diﬀerent aspects of RAM test.

5.5.2Firmware Upload

A complete ﬁrmware replacement can be done by uploading a ﬂash disk image ﬁle to the WebNet. As the existing ﬂashdisk contents are deleted and then replaced, all settings must be restored afterwards.

Upload is done via a minimal implementation of FTP („-FTP) that resides in a separate sector of the WebNet Flash, not on the ﬂashdisk itself. To enable this type of FTP, the WebNet must be booted with the „-FTP button on the “Test and service” page. After approx. 7 seconds, the WebNet is ready to receive a new ﬂash image. Assuming the ﬂash image is in a ﬁle called webnet.bin on a ﬂoppy in drive A on the PC, the steps are as follows:

1.Open a DOS-prompt and start the FTP-client: ftp 192.168.4.10 . NOTE: Only text based FTP-clients works with „-FTP (i.e. not through browser).

2.Set the ftp-client to “binary transfer” with the command bin .

3.Delete the existing ﬂash image with the command del flash (this command takes a while to return).

4.Transfer the new image with the command put A:nwebnet.bin’ (the destination ﬁle is implicitly the ﬂash ﬁle). The transfer may take up to a few minutes dependent on the network quality.

5.„-FTP may reboot the WebNet from the new ﬂashdisk with the command: quote BOOT .

6.Once the WebNet has started, close the FTP-client using the command bye . The Auto-IP feature now detects the IP-address (through the Auto-IP feature). As men- tioned, all settings should now be restored.
