points
(point)
*1 I/O control mode (refresh mode or direct mode) is selectable with the I/O control method setting switch.
*2 Only refresh mode is available, but there are instructions and devices that can use direct mode.
*3 Free space areas (except that in the program memory) can be used as user memory.
*4 Memory cassette is for copying programs to the ROM. Use of the cassette does not increase the memory capacity.
*5 Only one memory card can be used.
*6 This number means the number of applicable points for the access to actual I/O modules.
*7 The memory capacity corresponds to the maximum number of steps in a sequence program.
*8 The program capacity is included to a sequence program.
*9 The processing speed of the High-speed Universal model QCPU (QnUDVCPU) is 0.0019µs/step.
*10 The standard ROM capacity of the Q03UDVCPU, Q04UDVCPU, and Q06UDVCPU is 1025.5K bytes.
*11 The High-speed Universal model QCPU (QnUDVCPU) supports an SD memory card.
