Module
4.4.1 Uploading
Uploading is the process of reading the configuration
stored in the SM-EZMotion module and loading that data
into a file on the PC. Arrow B in Figure 24 represents a
standard Upload. To upload a configuration from the
SM-EZMotion module, first make sure the communications
settings are correct, and then click the Upload button on
the PowerTools Pro toolbar or select Device menu, Upload
command from the Menu Bar.
4.4.2 Downloading
Downloading is the process of sending the PowerTools Pro
configuration from the PC to the SM-EZMotion module.
Changes made in PowerTools Pro will not take effect until
the information has been downloaded or the Update to
RAM button has been clicked. Arrow A in Figure 24
represents a standard Download. To download information
to a SM-EZMotion module, click on the Download button
on the PowerTools Pro Tool Bar or select Device >
Download from the Menu Bar.
The first time a download is performed, PowerTools Pro
will lead the user through a series of dialog boxes to
configure the baud rate and COM port of the PC to be
used.
4.4.3 Non-Volatile Memory (NVM) Options for
Uploading and Downloading
When Uploading or Downloading, the user may be
presented with options on how to handle the values stored
in NVM memory. NVM is a type of memory that does not
lose its contents when power is removed. Values in RAM
are lost on power down, while values in NVM are retained.
Following is a description of the options the user may
encounter while uploading or downloading.
4.4.3.1 Uploading
When uploading from a SM-EZMotion module, the values
that were last downloaded are uploaded and put into a
PowerTools Pro configuration file (Arrow A in Figure 24). At
the completion of the upload, the user will be asked if they
wish to upload the NVM values. This dialog box is shown
below.
Figure 25: Upload NVM Option Window
By selecting Yes, the values of all parameters stored in
NVM will be uploaded and entered into the PowerTools Pro
configuration file values (Arrow H in Figure 24). If No is
selected, the values entered into the PowerTools Pro
configuration file will remain the same as those that were
last downloaded to the SM-EZMotion module.
4.4.3.2 Downloading
When downloading to the SM-EZMotion module the user
will be required to select how to handle the NVM
parameters upon downloading. Figure 26 shows the dialog
box asking the user to select one of three options for the
download.
Figure 26: Download NVM Option Window
A description of each of the options is as follows:
Overwrite
This option will overwrite all the parameters stored in NVM
with the current values in the user configuration (Just Arrow
A in Figure 24). The values that are in NVM prior to the
download will be lost.
Update
This option will upload the current NVM parameter values
from the SM-EZMotion module and enter them into the
user configuration. Once the NVM values have been
stored in the file, the file is fully downloaded (First Arrow H
followed by Arrow A in Figure 24. Data from H is saved in
PowerTools Pro configuration).
