Memory
NV Memory
Caution
Non-volatile (NV) memory data loss is possible when the NV write cycle is not fully completed. When
downloading a new application ensure data is not being written to NV memory.
FRAM Memory
DP7XX displays use Ferroelectric Random Access Memory (FRAM). FRAM has a write endurance of
over 100 trillion cycles, that is ideal for datalogging. 2kB is available for application.
Vault Memory
DP7XX displays have 16 MB of flash vault memory (application logging memory). Application
developers use this memory to log machine event data then use a USB stick or the PLUS+1 Service
Tool to extract the logged data.
Accessing non-volatile or application log memory can delay the service tool scan.
