*1 The file registers for each local device and program in which the program name is specified cannot be accessed.
*2 For Q12DCCPU-V (Basic mode), select "Use device function" on a C Controller module.
*3 For Q12DCCPU-V, only Q12DCCPU-V (Extended mode) can be accessed.
*4 The extended data register (D) and extended link register (W) can be accessed by the following two methods.
(1): Access by directly specifying the device name of the extended data register (D) and extended link register (W)
(2): Access to the file register (ZR) area assigned to the extended data register (D) and extended link register (W)
*5 Either of the device names can be specified.
*6 This is the device name in QCPU (Q mode), LCPU, and MELSEC-Q series C Controller module.
*7 It is not accessible when using Q00JCPU or Q00UJCPU.
*8 When accessing out of the range of the file register (ZR) area, the value of -1(FFFFH) is sampled.
