General Reference Guide Retrieving data from <strong>eWON</strong><br />
• The following files only appear if the user owns the "Config rights":<br />
• Program.bas<br />
• ewonfwr.edf<br />
• config.bin<br />
• config.txt<br />
• During an FTP session, all the files are read-only, except for users who own the "Config rights".<br />
7.2 Files Format<br />
Files format are text semicolon (;) separated files that may be inserted inside a program such as Excel. The first row gives the columns names,<br />
and the next ones the values of the different columns.<br />
For example, the content of the rt_alm.txt file:<br />
"TagId";"AlarmTime";"TagName";"AlStatus";"AlType";"StatusTime";"UserAck";"Description"<br />
1;"7/09/04 13:19:12";"Level tank A";"ALM";"LOW";"7/09/04 13:19:12";"";"Fuel level on Tank A"<br />
7.2.1 Config.txt : New Line character (NLSeparator)<br />
Firmware 5 specific feature<br />
For technical purposes, the character used (LF char 0x0A) to separate parameters in some fields is replaced by a .<br />
Fields where character could be found in config.txt are: IOServerData#, Information of <strong>eWON</strong>, Description of Tag.<br />
Fields where character could be found in comcfg.txt are: VPNSecretKey, VPNSecretCert, VPNCACert<br />
With firmware 5, you will find the following parameter:<br />
IOSrvData0:MinInterval:10MaxInterval:268435455ReverseCount:0<br />
has the ASCII code 182 (0xB6)<br />
The end of the line is always CR+LF (0x0D 0x0A).<br />
With firmware 4, you will find the following parametesr:<br />
IOSrvData0:MinInterval:10 ended by a LF character 0x0A<br />
MaxInterval:268435455 ended by a LF character 0x0A<br />
ReverseCount:0 ended by a CR+LF characters 0x0D 0x0A<br />
In firmware 5, you can force the use of ‘LF’ or ‘’ with the NLSeparator parameter (in config.txt file).<br />
NLSeparator<br />
0 (default) : use the ‘’ (0xB6) as separator in IOServerData# field.<br />
1 : use the ‘LF’ (0x0A) as separator in IOServerData# field (for<br />
compatibility with firmware 4).<br />
note: If the config is cleared or if the <strong>eWON</strong> is formatted, the NLSeparator returns to 0.<br />
note: When you put a config.txt file by FTP to an <strong>eWON</strong> with firmware 5, it handles correctly the 2 kinds of separator.<br />
