The average duration of the upload time is depending on the network connection speed. Within a 100 MBit
network and low processor load the upload time is less than 5s. The Service PC should be in the same
network as the devices. The upload speed could be quite low when you control the upload from remote via
a telecommunication network (not recommended). To avoid problems the FW checks the time between two
firmware data telegrams. If this time exceeds 5 s the upload process will be aborted.
8. By pressing of the "Refresh upload statistics" link you can observe the flash progress.
The flashing time is depending on the processor load. The supervision time for the flashing is 2 minutes.
After this time a warning is indicated but the flashing will be continued.
Attention! The power supply of the device shall not be switched off during upload and flashing.
If the reboot link "Now restart EN100 and wait 60 seconds" appears you may verify whether an upload was
successful with the system log site (http://<ip-address>/printf).
