Previous version (Ver. 3.0)
To transfer data changed in I/O memory
while monitoring, the monitor status had
to be cleared and then PLC | Transfer |
To PLC had to be selected, the range
specified, and the transfer specified in
the PLC Memory Window.
• Clear All Memory Areas Function
All Clear Operation for CPU Unit Memory (User Program, Parameter Area, and I/O Memory)
Previous version (Ver. 3.0)
Unless a memory error actually occurred in the PLC
the CPU Unit memory clear operation (see note) could
not be performed from the Error Log. Also there was no
function (all clear) to initialize the CPU Unit memory.

PLC | Edit Error Log had to be selected to display the
Errors window, and then the Clear All Button had to be
clicked.
• On-line Editing
Power Flow Monitoring during Online Editing
Previous version (Ver. 3.0)
The power flow could not be monitored
during online editing.
I/O Comment Changes during Online Editing
Previous version (Ver. 3.0)
Changes to I/O comments made during
online editing could not be saved in the
CPU Unit (see note).
If changes were made, the symbol table
file had to be transferred to file memory
in a CS-, CJ-, CVM1, or CV-series PLC
or to the I/O comment area in UM (user
memory) in a C-series PLC.
Note: New I/O comments could be
added to the symbol table in CX-
Programmer.
When the binary word display format is selected for the PLC Memory Window,
bit status is displayed both for individual bits and as hexadecimal word values.
Individual cells being monitoring in the PLC Memory Window can be selected
and the Set | Value command or the Set Value button can be used to display
the Set Present Value dialog box. Data can be input into this dialog box for
individual I/O memory address and then the OK Button can be clicked to
directly change the value in the PLC.
When binary values are being displayed, the menus and buttons can be used to
Set, Reset, Force On, Force Off, or Force Cancel individual bits.
The user program, Parameter Area, and I/O Memory in the CPU
Unit can be cleared to initialize the CPU Unit by selecting Clear
All Memory Areas from the CX-Programmer's PLC menu or
selecting Clear All Memory Areas from the Options menu of the
PLC Errors dialog box.
These operations are possible even if a memory error has not
occurred in the PLC (the same as they are for a Programming
Console).
New version (Ver. 3.1)
The power flow is displayed during online editing in monitoring status.
New version (Ver. 3.1)
I/O comments can be changed during online editing in Ladder diagram view,
in the Symbol Table, or in I/O Comment View.
If I/O comments have been changed when online editing is ended, a
confirmation message will appear asking if the symbol table file should be
transferred to file memory in a CS-, CJ-, CVM1, or CV-series PLC or to the I/O
comment area in the allocated UM (user memory) in a C-series PLC.
Note 1: Symbol table names and addresses cannot be changed during online
editing.
Note 2: I/O comments with symbol names cannot be transferred to the I/O
comment area in UM (User Memory) in C-series PLCs.
