CHAPTER 4 – Reference
Use the following procedure to add a symbol.
1, 2, 3...
Auto Generation of Symbols
It is possible to create symbols without giving them a name, but certain restrictions apply:
This can only be done in the Global Symbol table.
♦
An address and comment must be given.
♦
♦ The data type must be BOOL or CHANNEL.
These are called unnamed symbols, and normally they would appear in the symbol table or ladder diagram with
no name.
However, an option is provided to automatically generate a symbol name for unnamed symbols. The
Tools|Options|Symbols dialog contains a checkbox marked 'Automatically Generate Symbol Names'. If this
option is selected then names are automatically generated for unnamed symbols, and these names have a
standard format of AutoGen_[Address], where 'Address' is replaced with the symbol's address. If two or more
symbols of this type have the same address, a (Copy Of #) is suffixed, where # is a unique number.
