2) 2:The number of steps may vary depending on the device and type of CPU module being
used.
Component Nomber of basic steps
(1) When using the following devices only
• 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 index modification.
• Constant : No limitations
Note 1)

High Performance model QCPU
Process CPU
(2) When using devices other than (1)
Note 2)
4
Basic model QCPU
QnCPU
4 Note 2)
Note 1:With High Performance module QCPU, (1) requires more number of steps, while it can
process the steps faster, as compared with (2).
Note 2:The number of steps may increase due to the conditions described in Section 3.8.
3)
3 : The subset is effective only with QCPU.
