(c) When using the SRAM card which stores file register for 1018K points or more
For the High Performance model QCPU whose serial number (first five digits) is "16021" or later, Process CPU,
and Redundant CPU, the file register up to the area of 2M bytes can be used. Even if the file register for 1018K
points or more is specified using parameter or instruction, a stop error will not occur.

Differences in the file register processing time among CPU module versions
When the serial number (first five digits) of the High Performance model QCPU is "02092" or later, if the file
register is specified by the serial number access method (ZR
RAM, more processing time will be required per instruction than that of the High Performance model QCPU
whose serial number (first five digits) is "02091" or earlier.
• Q02CPU: 1.1 s (average)
• QnHCPU: 0.65 s (average)
Table9.12 below shows processing times when the MOV instruction is used.
