Appendix 2 CPU Performance Comparison

A
*1 The number of device points can be changed at the parameters.
*2 CPU 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 five 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.
*11 Only when L06CPU, L06CPU-P, L26CPU, L26CPU-P, L26CPU-BT and L26CPU-PBT whose first digits of serial number are "16042" or
later are used, the pointer for auto assignment device up to 32768 points can be used. (In order to use them, the PLC Parameter should
be set. For the PLC Parameter, refer to the MELSEC-L CPU Module User's Manual (Function Explanation, Program Fundamentals).)
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.
Data that can be used by instructions
