Appendix2 CPU PERFORMANCE COMPARISON
Appendix 2.1 Comparison of Q with AnNCPU, AnACPU, and AnUCPU
*1 : The number of device points can be changed at the parameters.
*2 : QCPU uses V as an edge relay.
*3 : Instructions that used accumulators with the AnNCPU, AnACPU, and AnUCPU have different formats with
the QCPU.
*4 : Can only be used by the $MOV instruction with the Q00JCPU, Q00CPU, and Q01CPU.
*5 : The Q00JCPU does not have file registers.
*6 : Applicable to products with the first 5 digits of the serial number 04122 or higher
(Q00JCPU, Q00CPU, and QCPU).
*7 : Each 5 points of FX0 to FX4 and FY0 to FY4 can be used on the programs.
*8 : The number of points that can be used on the programs
*9 : The number of accessible points to actual I/O modules
*10 : The Q00UJCPU does not have file registers.%ParaEnd%
Appendix 2.1.2 I/O control mode
TableApp.2.2 I/O Control Mode
Symbol in table : Usable, ––: Unusable
*1 : The DOUT, DSET, and SRST instructions are direct output dedicated instructions.
There are no dedicated instructions for direct input.
*2 : Switching between the refresh mode and direct mode is conducted with an AnNCPU DIP switch.
Appendix 2.1.3 Data that can be used by instructions

*1 : Applicable to products with the first 5 digits of the serial number 04122 or higher
(Q00JCPU, Q00CPU, and Q01CPU).
*2 : Usable with only the MOV instruction for the Q00JCPU, Q00CPU, and Q01CPU.
