Note: M238 and XBTGC use an internal battery. So in this case remanent variables are retained only if the internal battery is sufficient. M258/LMC058/ATV use flash technology and hence the remanent variables do not depend on the battery life.
The declaration of these remanent variables are made as below.
Persistent variables however have to be declared in a different way. They have to be declared on a special list, called Persistent Variables as they are related to the hardware being used.
Right-click on Application and select Persistent variables. The persistent variables need to be declared there. They will need to be on that list.
