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 which 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.
Unnamed Symbols
Unnamed symbols, like normal symbols, can be created in the Global Symbol Table, via the New Contact
dialogue (when a contact is entered on the Ladder) or via the Operand field of the Instruction dialogue (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 dialogue works in the same way as the Insert Symbol dialogue.
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.
Pasting Symbols with Errors
In the following example only two of the Symbols are correct the others are not, attempting to insert all these
Symbols into a symbol table will generate errors.
