Symbols
In the CX-Designer, it is possible to set a symbol as the data referenced by a functional object instead
of a directly specified host address or internal memory address.
Inputting an Address
Inputting a Symbol
Program maintenance can be simplified by converting the program to text so that the text indicates the
contents of each program address. Text comments can be added to each address to explain the con-
tents, but a more effective technique is specifying label names and symbol names in the address.
In the example above, the address SerialA:00048 is specified as a name with symbol TimeInterval.
This name can be used instead of the address. When the I/O configuration is changed, the variable
names allow you to make global changes to the entire project just by changing the address associated
with the symbol name so it isn’t necessary to change the addresses in the program individually. In the
CX-Designer, names and comments can be specified for address constants.
Symbols are registered in the symbol table. Registered symbols can be input in any communications ad-
dress setting.
