11. Selecting Show symbol bar in the Diagrams Tab in the Options Dialog Box of the Tools
Menu (the default setting is ON: display) enables the global/local, name, address/value,
and comment fields for the variable at the cursor position to be displayed in the symbol
bar below the Ladder Section window (CX-Programmer Ver. 4.0 or later). This increases
the program display density, while allowing the text in particularly long comments to be
checked, thereby improving the readability of the program.
12. View to show when split – enables two different views to be shown within the editing
window. It is possible to choose to see a part of the editing in mnemonic mode and the
other in ladder, or to see the local symbol table of the program in one view.
13. Setting the Show right bus-bar will show the right bus-bar with the ladder rungs justified
to fill the space between the left and right bus-bars. The output instructions will appear
aligned along the right bus-bar, as long as the rung can be drawn within the number of
cells to the right bus-bar. If the Expands to Widest Rung option is chosen, then the right
bus-bar position for a section is automatically set to the widest rung in the program
section. Note that this may result in slower performance on a large section when editing
or adding rungs, since if a rung is expanded beyond the current width, the section will be
reformatted.
If no right bus-bar is shown, the rungs are justified to the left, minimizing space.
14. Setting Show in simple dialog mode allows Contact, Coil or Instruction dialogs to open
in small sizes. The Show with comment dialog option allows dialogs to display for
entering comments in simple dialog mode.
15. Symbol filtering sets the target data of symbol filtering for the specified text string when
inputting instruction operands.
Name: Searches symbol names only.
Comment: Searches I/O comments only.
Both: Searches both symbol names and I/O comments.
16. Select the OK pushbutton to apply the settings and close the dialog. Select the Apply
pushbutton to change the settings but remain in the dialog. Select the Cancel pushbutton
to abort the operation.
1. Select the PLC tab within the Options dialog.
2. Set the Confirm all operations affecting the PLC setting to receive a confirmation
message for computer to PLC communications.
If a checkmark is placed in the Prohibit the online operations until the PC and PLC data
matches checkbox on the PLCs Tab Page that appears when Tools—Options is selected,
an Online Action Dialog Box to select either verifying or transferring data will be
displayed. Depending on the selection, before going online, the program will be verified
between the CX-Programmer and the PLC, the program will be transferred to the PLC,
or the program will be transferred from the PLC. Refer to Programming On-line in
Chapter 4 of PART 1 for details.

3. Select Tools
Options and Confirm all operations affecting the PLC in the PLCs Tab
Page (the default setting is OFF: no confirmation) to prevent going offline unprepared
when the CPU Unit is still in forced set/reset status (CX-Programmer Ver. 4.0 or later).
After forced setting/resetting of a bit online, a dialog box is displayed when status returns
to offline to allow the forced set/reset status of addresses to be displayed. The forced
set/reset status can also be cancelled.
4. Select the default PLC from the PLC Type field. When set CX-Programmer will show a
confirmation dialog when an operation being carried out may affect the running of a
PLC.
