10.1 Access to the eWON Technical Support
An eWON technical support is provided on our Web site (http://www.ewon.biz/). Just fill in the support request sheet (/Support/Support request),
or send your problem description to [e-mail]
. Our support team will provide you technical information to help you solving any issue you
could encounter to configure your eWON (even if we think that this User Manual answers the more exhaustively as possible to such questions),
or to integrate it or collecting information on your industrial networks.
10.2 eWON configuration and files storage
This chapter explains how the data storage is organized in the eWON.
10.2.1 Flash file system
The eWON uses a flash file system that uses a 8, 16 or 32 MBytes flash area.
The following files are saved in this flash file system:
Important:
“C” file type means that the file is a circular file. This kind of file has 2 sizes, the standard size and the maximum size. When the
maximum size is reached, the oldest 64K of data are erased and new data starts to be written. This means that the actual size of
data that has to be considered for a circular file is the standard size, because the maximum size is not permanent.
Formatting the Flash file system means erasing all the data in these files.
