Undoing and Redoing an Operation
An item in the Diagram Workspace can be restored to an earlier state. Select the
Undo
button
from the toolbar to undo the last action. Select the
Redo
button from the toolbar to re-apply an
action.
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 which 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 dialogue 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 dialogue available from their
context sensitive menu.
♦
PLC
.
The name of the PLC can be changed by entering a new name in the Change PLC dialogue 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
dialogue.
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.
