*1 The local devices and file registers for individual programs cannot be accessed by specifying the program name.
Do not use local devices and file registers for individual programs since they may not be read/written correctly.
*2 Process CPU does not support high speed sampling.
*3 Access to a safety device is not available.
*4 For Q12DCCPU-V (Basic mode), select "Use device function" on a C Controller module.
*5 For Q12DCCPU-V, only Q12DCCPU-V (Extended mode) can be accessed.
*6 The extended data register (D) and extended link register (W) can be accessed by the following two methods.
●Specifying extended data register (D), extended link register (W) directly
●Accessing the file register (ZR) region assigned to the extended data register (D) or extended link register (W)
*7 Either of the device names can be specified.
*8 A device name for QCPU (Q mode) and LCPU.
*9 When accessing out of the range of the file register (ZR) area, the value of -1(FFFFH) is sampled.
*10 It is not accessible when using Q00JCPU and Q00UJCPU.
*11 RnENCPUs and safety CPUs do not have the CPU buffer memory access device (fixed cycle communication area) (U3En\HG).
