Note: The action of going on-line and offline to/from a PLC empties the memory of undo operations
for that PLC, so that it is not possible to undo operations that were made previously.
Deleting Items
Most items within a project can be deleted – although restrictions apply when the PLC is on-line. A project
cannot be deleted. The following rules apply to deleting an object:
♦
If a PLC is deleted all associated items are deleted. Individual components (apart from the program(s)), for
example an IO Table cannot be deleted separately.
♦
A PLC cannot be deleted if it is currently opened for communications or if it is acting as a gateway PLC.
♦
If a program is deleted, its associated (local) symbol table is deleted.
♦
A global or local symbol table cannot be deleted except as part of a PLC deletion (both types of table) or
program deletion (local symbols).
♦
PLC pre-set symbols in the global symbol table cannot be deleted. Entries in the local symbol table can be
deleted.
♦
All entries in the Ladder program and Mnemonics view can be deleted (provided the PLC is offline).
Use the following procedure to delete an object.
1, 2, 3… 1. Select the object in the project workspace or items in the Diagram Workspace.
2. Select Delete from the context sensitive menu. A confirmation dialog is displayed when
deleting PLCs and programs.
3. Select the Yes pushbutton to confirm the deletion. Select the No pushbutton to abort the
operation.
Renaming an Object
A number of objects in the project file can be renamed (unless the PLC is on-line):
♦
Project, Program, and Section . These can be renamed by simply typing a new name over the existing one
in the project workspace tree. They can also be changed via their Properties dialog available from their
context sensitive menu.
♦
PLC . The name of the PLC can be changed by entering a new name in the Change PLC dialog supplied by
the CX-Server application, available from its context sensitive menu. Refer to the CX-Server PLC Tools
User Manual for further information.
♦
Individual objects including symbols . These names can be changed by displaying the appropriate Edit
dialog.
Note: CX-Server components, for example the IO Table, cannot be renamed.
Field Descriptions
The global and local symbols tables display information in tabular form. The fields are identified by column
headers; these columns can be resized and information displayed according to preference.
To resize column width, select the required field division and drag to the desired width. The tabulated
information can also be sorted by selecting the appropriate field division. The manner in which the information
is displayed can be altered by selecting the appropriate icon.
Select the Large Icons button from the toolbar to display content as large icons.
Select the Small Icons button from the toolbar to display content as small icons.
Select the List button from the toolbar to display content as a list.
Select the Details button from the toolbar to display content with associated details.
Next Reference
The Next Reference command works with the Output Window . It jumps the program display to the point
referred to on the next line of the output window.
