*1 For the timer, retentive timer, and counter, contact/coil values are stored in bit devices, and current values are stored in word devices.
*2 The number of points that can be actually used varies depending on the intelligent function module. For the points in the buffer memory,
refer to the manual for the intelligent function module used.
*3 The number of points can be changed (except for input, output, and step relay) in the Device tab of the PLC parameter dialog box. Note
that the step relay points can be changed to 0 point for the Universal model QCPU whose serial number (first five digits) is "10042" or
later. For the Universal model QCPU whose serial number (first five digits) is "12052" or later, the step relay points can be set in
increments of 1k points and up to the following points.
 Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU: 8192 points
 Universal model QCPUs other than the Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU: 16384 points
*4 Available only in a multiple CPU system configuration.
*5 Up to 15 digits can be entered in GX Developer.
*6 The total of the points for the file register, extended data register (D), and extended link register (W)
*7 The device cannot be used on the Q00UJCPU.
*8 For the Q00UJCPU, Q00UCPU, and Q01UCPU, the number of points is 512.
*9 For the Q00UJCPU, Q00UCPU, and Q01UCPU, the range is P0 to P511.
*10 For the Q00UJCPU, Q00UCPU, and Q01UCPU, the number of points is 128.
*11 For the Q00UJCPU, Q00UCPU, and Q01UCPU, the range is I0 to I127.
*12 For the Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU, the range is BL0 to BL127.
*13 The range differs depending on the CPU module: U0 to UF for the Q00UJCPU; U0 to U3F and U3E0 to 3E2 for the Q00UCPU and
Q01UCPU; and U0 to U7F and U3E0 to U3E2 for the Q02UCPU.
*14 For the Universal model QCPU whose serial number (first five digits) is "12011" or earlier, the number of points is 8192.
*15 For the Universal model QCPU whose serial number (first five digits) is "12011" or earlier, the range is Jn\X/Y0 to Jn\1FFF.
*16 For the Q50UDEHCPU and Q100UDEHCPU, the number of points is 128k.
*17 For the Q50UDEHCPU and Q100UDEHCPU, the number of points is 8192.
*18 For the Q50UDEHCPU and Q100UDEHCPU, the range is P0 to P8191.
*19 The changeable range differs depending on the CPU module: within 30k words for the Q03UDVCPU; within 40k words for the
Q04UDVCPU and Q06UDVCPU; and within 60k words for the Q13UDVCPU and Q26UDVCPU.
*20 The number of points differs depending on the CPU module: 9216 for the Q03UDVCPU; 15360 for the Q04UDVCPU and Q06UDVCPU;
and 28672 for the Q13UDVCPU and Q26UDVCPU.
*21 The range differs depending on the CPU module: M0 to M9215 for the Q03UDVCPU; M0 to M15359 for the Q04UDVCPU and
Q06UDVCPU; and M0 to M28671 for the Q13UDVCPU and Q26UDVCPU.
*22 The number of points differs depending on the CPU module: 13312 for the Q03UDVCPU; 22528 for the Q04UDVCPU and
Q06UDVCPU; and 41984 for the Q13UDVCPU and Q26UDVCPU.
*23 The range differs depending on the CPU module: D0 to D13311 for the Q03UDVCPU; D0 to D22527 for the Q04UDVCPU and
Q06UDVCPU; and D0 to D41983 for the Q13UDVCPU and Q26UDVCPU.
*24 The setting range differs depending on the CPU module: 0 to 4192k points for the Q03UDVCPU, 0 to 4224k points for the Q04UDVCPU,
0 to 4480k points for Q06UDVCPU, 0 to 4608k points for the Q13UDVCPU, and 0 to 4736k points for the Q26UDVCPU.
*25 For the Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU, the number of points is 128.
