*1 When changing the device points, new setting must not exceed the refresh ranges of network modules or the auto
refresh ranges of intelligent function modules. If a new device point setting exceeds the corresponding device range, the
data may be written to another device or an error may occur.
*2 When a device latch range is set, the scan time increases. When latching a device, consider the increase in the scan
time. (
*3 For the Universal model QCPU whose serial number (first five digits) is "10042" or later, the points for step relay (S) can
be changed to 0K. For the Universal model QCPU whose serial number (first five digits) is "12052" or later, the points for
step relay (S) can be set up to the following in increments of 1K points. (
• Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU: 8192 points
• Universal model QCPU other than the Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU: 16384 points
*4 Available only when the serial number (first five digits) of the Universal model QCPU is "10042" or later.
*5 When using the index register as a local device with the Q03UDCPU, Q04UDHCPU, Q06UDHCPU, Q13UDHCPU,
Q26UDHCPU, or QnUDE(H)CPU, check the versions of the CPU module and programming tool used. (

*6 Not available for the Q00UJCPU.
*7 For the Universal model QCPU whose serial number (first five digits) is "10042" or later, the maximum number of points
for the internal relay (M) and link relay (B) is 60K. (
*8 The setting range differs depending on the CPU module.
• Q03UDVCPU: 30K words
• Q04UDVCPU, Q04UDPVCPU, Q06UDVCPU, Q06UDPVCPU: 40K words
• Q13UDVCPU, Q13UDPVCPU, Q26UDVCPU, Q26UDPVCPU: 60K words
*9 The default value differs depending on the CPU module.
• Q03UDVCPU: 9K points
• Q04UDVCPU, Q04UDPVCPU, Q06UDVCPU, Q06UDPVCPU: 15K points
• Q13UDVCPU, Q13UDPVCPU, Q26UDVCPU, Q26UDPVCPU: 29K points
*10 The default value differs depending on the CPU module.
• Q03UDVCPU: 13K points
• Q04UDVCPU, Q04UDPVCPU, Q06UDVCPU, Q06UDPVCPU: 22K points
• Q13UDVCPU, Q13UDPVCPU, Q26UDVCPU, Q26UDPVCPU: 41K points
*11 Only the High-speed Universal model QCPU and Universal model Process CPU can select "Time Setting". The latch
interval setting is fixed to "Each Scan" for other CPU modules.
Description
Set points for the file register (ZR),
extended data register (D), and
H
extended link register (W).
Set a latch range (start and end
device numbers), which can be
H
cleared by a latch clear operation.
Set a latch range (start and end
device numbers), which cannot be
H
cleared by a latch clear operation.
Select Z or ZZ device for 32-bit
H
indexing.
Set a latch interval.
H
Set whether to use the write-
protect function for device data
(from outside the CPU module).
Set the write-protected range (set
the start device number and the
H
end device number). To set this
item, select the checkbox of
"Disable device write from
external".

Setting range
Point assignment to the file register
(ZR), extended data register (D), or
extended link register (W). Assign part
of the points of the file register to the
extended data register and extended
link register.
Each latch range for the file register
(ZR), extended data register (D), or
extended link register (W).
Each latch range for the file register
(ZR), extended data register (D), or
extended link register (W).
Z0 to Z18 (when using Z device)
1 to 2000ms
-
One range per device (available to X, Y,
M, L, B, F, SB, V, S, T, ST, C, D, W, SW,
Z, ZR (R), extended data register,
extended link register)
