MultiSmart Installation & Operation Manual
22.2.10 File transfer over DNP3
The MultiSmart supports file transfer over DNP3. This can be used for various operations such as changing
the MultiSmart configuration, upgrading the firmware, changing the DNP3 point list, changing the ISaGRAF
programs running on MultiSmart, retrieving log files, etc.
22.2.10.1 Bulk Configurations
A bulk configuration can be transferred to the MultiSmart using DNP File Transfer. Then, by sending an
Activate Configuration Command with the same file name, the configuration can be activated.
The bulk configuration file name must be called bulkcfg.tgz. (The file can also be of the form
WITSCFG\bulk_version.dat when WITS-DNP is enabled.) This file can be generated by either exporting
to an SD card or USB via the LCD, or else via the MultiSmart Configurator.
DNP File Transfer can also be used to retrieve the existing MultiSmart configuration in bulk configuration
format.
22.2.10.2 Upgrade Image
An upgrade image can be downloaded into the MultiSmart by using the DNP File Transfer command. Then
an Activate Configuration Command will confirm the upgrade, and the unit will reboot with the upgraded
firmware.
The file name must be multismart.img.
In order to do an upgrade via DNP, an SD card must be mounted in the MultiSmart. Because of the size of
this file(~18 MB), the transfer process can be very time consuming, especially over slow communication
links.
22.2.10.3 ISaGRAF programs
ISaGRAF programs can be transferred to the MultiSmart using DNP File Transfer command. Sending an
Activate Configuration Command with the complete file name will activate the ISaGRAF programs
transferred.
The file name must be isagraf.tgz. (The file can also be of the form WITSCFG\app.dat when WITS-
DNP is enabled.)
ISaGRAF programs running on a MultiSmart can be retrieved using DNP File Transfer command.
22.2.10.4 Point Lists
Using DNP File Transfer, a comma separated point list can be transferred to the MultiSmart. Then by
sending an Activate Configuration Command with the file name, the point list can be activated.
The points list file must be called dnps.csv, or else dnps.csv.gz. Both of these files can be exported via
MultiSmart Configurator. Using the .gz format will result in a much smaller file and faster transmission and
activation of the points list.
A significant advantage of downloading and activating points lists is to change event classes or deadbands
of points. This mechanism can also be used to add or delete points in the list.
DNP File Transfer can be used to retrieve point lists in a comma separated format from a MultiSmart.
22.2.10.5 Log files
Log files from MultiSmart can be retrieved over DNP3 using DNP File Transfer.
The file name used to retrieve log files must be logs.tgz.
