11.0 ACCESSING FILES FROM AND PERFORMING UPDATES TO
THE CONTROLLER
The controller has a total of about 92 MB of internal memory. There are several types of files
that use the internal 92 MB of mass storage that are available on the controller.
u
Logs—exported automatically in the root
u
Alarm List—exported on demand
u
Parameter sets —see
Restore Parameters (Settings)
u
Program and OS Upgrade packages—Reside in an UPGRADE folder
u
Web pages—Reside in an HTTP folder
u
User storage, such as documents
These files can be accessed through one of two methods:
u
Connection via FTP through the Ethernet port
u
Connection with a micro USB cable
It is also possible to export directly alarms, current log, and parameter sets to a USB drive that
has either a micro USB connector or uses an adapter.
NOTE: You cannot
be connected by
both methods at
the same time. If
you are viewing the web
pages and then connect
with USB, the web page
will go blank until
you disconnect.
The controller has a built-in USB port where an external memory device such as a USB thumb
drive can be plugged in. The external memory device may be used for backing up all settings
and reported conditions such as Alarm History and presets. Backing-up is user-commanded
and is done through the menu screens.
Note that the USB port is a Micro USB Type “B.” Thumb drives with a Micro USB Type B are
difficult to find in some areas and it may be necessary to purchase an adapter to go from a
more common Type A connector to the newer Micro Type B.
Make sure that the longer side of the USB connection is to the bottom of the controller. Do not
force the connector in or you could damage the controller.
The controller requires that you use a cable or adapter with a longer end for the Micro USB side.
One adapter we have found that works is the UGreen, purchased on Amazon.
