File Download/Upload Functions 
The following is a general description of file transfers between the controller and computer devices external 
to the controller.  
 
 
CAUTION 
Performing download procedures incorrectly could cause loss of control in an 
operating process or loss of data and program files in a controller.    
Refer to the appropriate User's Manuals for download/upload procedures. 
Failure to comply with these instructions may result in product damage. 
 
Two types of software files can be downloaded to the controller: 
•  Configuration files 
•  Firmware files. 
Configuration files can also be uploaded from the controller for archiving.  Firmware can only be 
downloaded to the controller.  Pathways for file transactions between the controller and computer devices 
external to the controller are shown in Figure 82.
