Appendix 2CPU PERFORMANCE COMPARISON
Appendix 2.1Comparison of Q, LCPU with AnNCPU, AnACPU, and AnUCPU
*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 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.
Appendix 2.1.2 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.
