Processor modules are equipped with non-removable and non-volatile onboard user flash memory for program and data storage. The integrated flash management, including a wear levelling algorithm and a power-fail protected file system, is designed for robustness and operation in industrial environments and applications. The user flash memory can be accessed from the user program using the CAA_File library .
Important: Programmers should keep the amount of cyclic written data low to ensure long availability.
