Changing Allocated Addresses

1,2,3...

The CX-Designer can enter addresses as symbols when setting functional
object addresses. (Addresses can also be directly input, the same as for the
NS-Designer. Symbols are automatically allocated in these cases.)
This means that all addresses used in a project can be managed from the
symbol table.
The following operations can be performed easily using the symbol table.
• Changing allocated addresses when the address allocation changes sud-
denly.
• Reusing existing projects in another system.
Symbols can also be copied and pasted between the CX-Programmer and
CX-Designer symbol tables.
Also, any I/O allocation table created using Excel or other software can be
used as is in symbol tables.
Register symbol
names for ladder
program and other
PLC addresses using
CX-Programmer.

Copy/paste via Excel.
If an address allocated for a symbol is changed on a symbol table, the change
is automatically reflected in all screens.
This allows allocated addresses to be changed simply by changing the sym-
bol table, instead of opening each screen and changing the property settings
for the functional objects on that screen.
There is flexibility with symbol changes to meet any requirement. The replace
function can be used to globally replace the host and addresses. Symbols can
also be changed individually.
Procedure
1. Select Symbol Table on the project workspace Common Setting Tab
Page. The symbol table will be displayed.
2. Double-click the symbol for which the allocated address is to be changed
in the symbol table.
3. Change the allocated address in the displayed Address Settings Dialog
Box.
Register symbol names
for PLC addresses using
CX-Designer and use
symbol names to specify
object addresses.
