Hi all!

I have a problem. In the Installation tab ->Safety-> I/ O, I changed the function assignment for input and output signals. After saving this configuration and restarting the robot I can't start the program. A safety message about the failure is displayed. The error code is: C283A14: Safety system: Operation mode input mismatch between SCB A and SCB B. I can't start the robot after entering the initialization screen. Everything worked fine before this change. I would like to add that the inputs and outputs that I was editing concerned configurable security inputs and outputs to which some elements were already connected.

The problem is that at the moment I can't go into manual mode to go to the installation tab and restore the previous settings. After attempting to enter this mode, a message about security configuration change is displayed, which must be confirmed in manual mode.

How to switch to manual mode or restore previous installation settings? Another question is whether it is possible to create a new installation and upload a working program - will this solve my problem? 

Thank you in advance for your help

    Hi Listerin, 
    When you changed the settings did you change them to "operational mode"?
    I also speak with the Universal Robot support agent and they need at least a picture or your error code and if possible the installation backup of your robot.
    If you can provide me these information they will be able to help you.
