<strong>General</strong> <strong>Reference</strong> <strong>Guide</strong> Appendix<br />

An <strong>eWON</strong> technical support is provided on our Web site (http://www.ewon.biz/). Just fill in the support request sheet (/Support/Support request),<br />

or send your problem description to support@ewon.biz. Our support team will provide you technical information to help you solving any issue you<br />

could encounter to configure your <strong>eWON</strong> (even if we think that this User Manual answers the more exhaustively as possible to such questions),<br />

or to integrate it or collecting information on your industrial networks.<br />

10.2 <strong>eWON</strong> configuration and files storage<br />

This chapter explains how the data storage is organized in the <strong>eWON</strong>.<br />

10.2.1 Flash file system<br />

The <strong>eWON</strong> uses a flash file system that uses a 8, 16 or 32 MBytes flash area.<br />

The following files are saved in this flash file system:<br />

Table 205: Flash file system - files type and size<br />

Important:<br />

"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<br />

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<br />

data that has to be considered for a circular file is the standard size, because the maximum size is not permanent.<br />

Formatting the Flash file system means erasing all the data in these files.<br />
