Allowing/Prohibiting Program Overwriting (CS/CJ-series CPU Unit Ver. 2.0 or Later)
Previous version (Ver. 3.3) New version (Ver. 4.0)
Overwriting the user program
in the CPU Unit was
prohibited by turning ON pin 2
of the DIP switch. If pin 2 was
turned OFF, however,
overwriting was possible.
When a password is registered for the whole user
program or individual tasks, an optional setting can be
selected at the same time to allow/prohibit program
overwriting. Set the option in the PLC properties.
This function uses a password to prohibit overwriting of
the program by a third party.
Improvements to I/O Table Editing Functions
•
Specifying up to 64 Sets of Slot/Rack Start Addresses
Previous version (Ver. 3.3) New version (Ver. 4.0)
For CS/CJ-series PLCs, up to
eight sets, comprising
rack/slot number and start
address, could be set.
For CS/CJ-series PLCs Ver. 2.0 or later, up to 64 sets
of rack/slot numbers and start addresses can be set.
Improvements to Unit Error Log Display

Displaying Error Log for CPU Bus Units or Special I/O Units in the I/O Table
Previous version (Ver. 3.3) New version (Ver. 4.0)
The error log could not be
displayed for Special I/O
Units.
By selecting a CPU Bus Unit or Special I/O Unit in the
I/O table tree and clicking the right mouse button to
select the Unit Error Log Menu, the error log for the
selected Unit can be displayed.
Improvements to Ladder Screen Display Functions
•
Addition of Horizontal Display Mode for Instructions
Previous version (Ver. 3.3) New version (Ver. 4.0)
Instructions could be
displayed in vertical writing
only.
Instructions on the right side of rungs, which were
previously displayed vertically only, can now also be
displayed horizontally. Enable this function by selecting
Tools – Options , and then selecting Show output
instructions horizontally in the Diagrams Tab Page (the
default setting is OFF: previously used vertical display).
By using the horizontal display mode, the number of
instruction rungs that can be printed and displayed on
one screen is increased, improving the readability of
the program. At the same time, the number of printed
pages can be reduced.
