Find and Replace
If the ‘Automatically Generate Symbol Name’ option is selected then the ‘unnamed’ symbols can be found in a
Find and Replace operation that searches for Symbol Names. If the checkbox is left unchecked symbols will not
be found in the Find or Replace.
Copying and Pasting
When copying ladder objects and pasting to another ladder, the results depend upon the ‘Automatically Generate
Symbol Name’ checkbox. If it is checked, then the auto-generated symbol name is pasted (but without the
address). If it is unchecked, then the address only is pasted.
Data can be copied and pasted between CX-Programmer symbol tables and CX-Designer variable tables with
CX-Programmer Ver. 7.2 (CX-One Ver. 2.1) or higher.
Unnamed Symbols
Unnamed symbols, like normal symbols, can be created in the Global Symbol Table, via the New Contact dialog
(when a contact is entered on the Ladder) or via the Operand field of the Instruction dialog (when an Instruction
is entered on the Ladder).
Editing Symbols
It is possible to edit symbols by double clicking symbols from the symbol table, or from an operand within a
program. The dialog works in the same way as the Insert Symbol dialog.
When a symbol’s address or comment is altered, the program or programs using it automatically use the new
address and show the new comment.
When a symbol is renamed, the program will automatically use the new name. If an override symbol is deleted,
the program attaches to the global definition.
When a symbol is deleted from the symbol table any operands that are currently linked to that symbol will be re-
linked to new symbols. The symbols are searched for using the order of precedence rule. If a new match is found
then the operand will be linked to the new symbol. If however no match is found then the operand reverts to the
physical address of the deleted symbol.
When copying symbol table data in CX-Programmer version 8.0 or higher, the items to be copied and the order
of the data to be copied to the clipboard can be set.
