(3) Memory capacities and necessity of formatting
Table5.5 provides the memory capacities and necessity of formatting of each memory.
Format a memory requiring formatting by GX Developer beforehand.
*1: When the memory contents become indefinite in initial status or due to the end of battery life, the memory is automatically formatted after
the CPU module is powered off and then on or is reset.
*2: The standard RAM capacity of the High Performance model QCPU varies depending on its version. ( Appendix 2.2)
● When files are written to each memory, the unit of stored file size depends on the target CPU module and memory
area. ( Section 5.4.4)
● In memory capacity calculation, 1 step is equal to 4 bytes.
