ence of multiple programs.When processing any program, the corresponding local device
data is transferred from the local device area to the executing device area and program
processing is then performed.

Debugging data
Trace result storage file for the trace function used for program debugging.
ā
Data file written by a FWRITE instruction
These data can be stored on ATA memory cards (Q2MEM-8MBA/16MBA/32MBA)only.
Memory Cards
All PLC CPUs of the MELSEC System Q except the CPU modules Q00JCPU, Q00CPU and
Q01CPU can be equipped with a memory card.
Before the memory card can be used for the first time the memory card must be formatted by
GX Developer or GX IEC Developer.
A program stored in a memory card is transferred to the program memory at power-on and exe
-
cuted in the program memory. The behaviour at power-on can be set in the parameters (Boot
file).
