Where:
• <uid>: Concentrator identier (site).
• <timestamp>: The timestamp format is “YYMMDD_HHMMSS” so that an alphabetical sort of
the directory gives the chronological order.
• <interface>: the interface name from a dened list (see section 3.1.2.1.3.4: “Declaration of
equipment to be supervised”).
• <comment>: free user eld.
• <version>: update version number.
The data, alarm and log les are compressed to the Gzip format “.gz”.
The minimum access rights to the different directories must be dened as specied in the table above.
If the directories are not created at the concentrator connection, or if the rights are not sufcient
to upload or download les, contact the server administrator.
All les exchanged between the concentrator and the server must have standard UTF-8 encoding.
Operation:
In FTP or SFTP, if the “FTP_TwoStepsSendingDisabled” or “FTP2_TwoStepsSendingDisabled” parameter
equals “1”, the concentrator uploads the les to the server using a 2 step process:
• At the start of the transfer the le has an additional “.tmp” extension.
• When the le transfer is complete, it is renamed by removing the “.tmp” extension.
This process allows the remote server to easily differentiate between les being uploaded and les that
are completely uploaded.
For a WebDAV-HTTPS server, this mechanism is useless.
File formats:
The concentrator manages different formats depending on the le type. They can be grouped by extension:
EXTENSION FILE TYPE DESCRIPTION
.ini •Concentrator conguration le
•Connection schedule le
•Data le (compressed)
