5.  Software 
5.1  Software Updates 
Universal Robots software is called PolyScope. 
CAUTION 
•  Read  these  instructions  and  the  instructions  on  our  support  website 
(www.universal-robots.com/support)  completely  prior  to  updating  your 
software. Universal Robots assumes no responsibility for failed updates caused 
by improper operation. 
•  Control Box power MUST NOT be turned off during the software update process. 
Failure to meet this demand is likely to cause loss of data and malfunction. 
•  Keeping the robot software up to date is required to ensure safe operation. Also, 
the latest software provides more features and a better performance. 
•  Read the Release Notes of the software you install. Release Notes hold notes 
about the software changes which in some cases are relevant for safe operation 
of the robot. 
•  Updating  the  software  may  cause  changes  to  functionality.  Robot  motions 
might change or be subjected to different restrictions. 
•  In case of questions or concerns related to your application please contact your 
supplier for advice and assistance. 
 
Not all combinations of updates are possible. These are the rules to observe: 
•  If running PolyScope 5.5.0 and above: 
Update directly to PolyScope 5.8.0 or any later version. 
•  If running PolyScope 5.4.3 and below:  
Updates must be done incrementally in steps of one minor version.  
E.g. PolyScope 5.2.1 → 5.3.1 → 5.4.3 → 5.5.1.  
When PolyScope 5.5.0 is reached, software can be updated directly to the latest version.  
 
Therefore, when updating your robot software care must be taken to select a proper update path. 
Several update steps will be necessary until reaching a version of 5.5.0. 
Downgrading  software  is  not  supported.  In  PolyScope  5.5.0  backup  and  restore  functionality  is 
added  and  this  is  the  recommended  way  to  go  back  to  any  prior  version  installed. We  strongly 
recommend that you precede any update cycle with a backup to counter the situation of a failing 
update. Please contact your supplier if updating causes any trouble.
