* 1 : The standard ROM is used in the following cases.
•For High Performance model QCPU, Process CPU, and Redundant CPU
Writing a program memory to ROM.
•For Universal model QCPU
Storing device comment or user data.
* 2 : The standard RAM is a memory provided for using the file registers, local devices and sampling
trace file without installing a memory card.
The standard RAM is used to speed up access to the file registers.
* 3 : The intelligent function module parameters set by GX Configurator are included.
* 4 : When the sampling trace file is stored in the standard RAM, check the version of the CPU module
and GX Developer. (
* 5 : Only available for the Flash card.
Only read is enabled in PLC program.
* 6 : Refer to the following manual for the CPU shared memory.
QCPU User's Manual (Multiple CPU System)
* 7 : The Universal model QCPU cannot store an error history in the memory card.
* 8 : Can be stored only when the Universal model QCPU is used.
