• Word device: Internal device (except for file register ZR)
• Bit device: Devices whose device Nos. are multiples of 16, whose digit
designation is K8, and which use no indexing.
• Constant: No limitations
Devices other than above
All devices that can be used
Note 1) When using a High Performance model QCPU, Process CPU or Redundant CPU,
the number of steps increases but the processing speed becomes faster.
Note 2) The number of steps may increase due to the conditions described in Section 3.8.
