� Shortened startup time with sampling trace function
The sampling trace function facilitates error analysis and program debugging timing
verification, reducing equipment error analysis time and startup time. For a multiple CPU
system, CPU-to-CPU data exchange timing can be also confirmed.
The collected data can be not only viewed on GX Developer but also exported to a CSV
file, allowing data analysis utilizing Excel.

[Bit device extension]
The points can be set within the range from
0 k to 60 k points for the internal relay (M)
and link relay (B).
[Extended data registers/extended link registers]
For example, 640 k points of word device in
the standard ROM area can be divided as
follows according to the purpose of use for
Q26UDEHCPU.
・File register (R): 128 k points
・
Extended data register (D): 256 k points
・ Extended link register (W): 256 k points
� Improved program creation with device extension
[Bit device extension]
The bit devices M and B can be extended up to 60 k points, improving
program readability. (Previously up to 32 k points)

[Extended data registers/extended link registers]
The device range is extended by using the standard ROM or memory card as D device or
W device. (Previously used as file register (R/ZR))
Devices can be extended easily and flexibly for such case as word device increase by the
program change.

� Simplified program debugging task
The QnU model features the "Executional conditioned device test" function, which allows
the user to change the device value to the specified value at any step in the program.
Previously, a program for device setting must be added to debug a specific ladder block.
However, using this function, only the specified ladder block can be debugged without
modifying the program. This eliminates the program modification time for debugging and
simplifies the debugging task.

Upgraded Function
Execute the device test by
setting the conditions such as
step No. and execution timing
(before/after executing
instruction).
The section to be debugged is
in a colored box for easy confirmation.
All sections to be tested are displayed in a list. Reading the
registered conditions from the CPU and saving/reading the
execution condition file are available.
