Flash Memory for AC500 V3 Products

AC500 Processor Modules for V3 products (PM56xx) 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: CAA_File Library

Attention

The User Flash Memory has a finite number of write cycles.

Note

Important: Programmers should keep the amount of cyclic written data low to ensure long availability.
