Hello, 
 

 I have some variables in my program. User can change them from HMI, but I need keep this change in BL4S200. So user is able to power off BL4S200 and power on again. the variable still have the value that user changes it before the last power off.
 

 I try bbram and protected, but it seems it doesn't work.
 

 Does anybody know how to do it?
