When making any changes to the
RW memory area, the changes are stored in RAM memory initially and after 60
seconds, written to permanent flash memory. Therefore, when testing the RW
memory, make sure you wait at least 60 seconds before cycling power on the HMI
or the changes will not be saved permanently. Here is an explanation from the
“EBPro Programming Manual.”

As described above, there is a
system bit (LB-9029) that you can use to force the HMI to save any changes to
the RW memory immediately by turning the bit ON.
