If you attempt to load a file onto your meter's FTP site that is too large, your FTP
program displays an error, and you must delete files from your meter's internal
FTP site to free up memory before loading the file.
If you modify a meter feature which uses FTP memory, such as increasing the
number of COMTRADE waveform records, the meter checks to confirm sufficient
space is available on its internal FTP site before enabling the modified feature. If
there is insufficient space, the feature is disabled, and you must delete files from
your meter's FTP site to increase the available space before enabling the feature.
Your meter has an FTP folder structure.
• COMTRADE: you can read COMTRADE files from these folders, but you
cannot delete or add files to these folders.
• IEC61850: you can add an IEC 61850 configuration (CID) file to this folder to
activate the IEC 61850 protocol functions of your meter.
• optionModuleUpg and rmdUpg: you can load firmware update files for your
meter's remote display or option modules into these folders.
• documents: this folder is intended for user storage. You can read, write and
delete any type of files in this folder.
• web: this folder is where the meter's default webpages are stored and where
you can add custom webpages to the meter by copying them into the
appropriate subfolders.
FTP filenames are limited to standard ASCII characters.
This means that they cannot contain a blank space, quotation marks or \, /, *, ?, <
or >, and are limited to 68 characters in length, including the file extension. The "/"
character is only used as part of the FTP file directory information.
Your meter supports SNMP once you have enabled SNMP on your meter. You
need to upload the meter's MIB file (available from www.usa.siemens.com/pds)
into the NMS managing your meter.
Simple Network Management Protocol (SNMP) is part of the Transmission Control
Protocol/Internet Protocol (TCP/IP) protocol suite. SNMP is an application layer
protocol that enables the exchange of network management information between
devices, allowing you to manage network performance and to identify and solve
problems on networks with devices of various types.
SNMP configuration assumes that you have an advanced understanding of SNMP
and the communications network and power system that your meter is connected
to.
Term Definition
Agent Software resident on the managed device which interfaces between the
device and the NMS.
Managed device Your meter in the SNMP network.
Community name/ A text string that helps authenticate requests between the managed
string device and the NMS.
Managed object Any parameter referenced in the MIB file.
MIB A management information base which organizes the OIDs in a
hierarchical tree.
