replacement of ‘#10’ will actually show as ‘#16’ back in the program display for a BCD
operand.
It is possible to move a range of integers to a new starting point, using the same method as 'Moving Addresses'.
Changing TIM/CNT Operands
It is possible to change the first operand of a TIM/CNT instruction easily, at the same time as changing the
address used for its status bit. To do this, use the ‘Address’ look-at type, and type in the address of the status
bit/s to operate on (e.g. T0001). This will also find the first operand of a timer/counter instruction (e.g. If
T0001 is looked for, then ‘1’ will also be found in the TIM instructions).
Therefore, it is possible to change a range of TIM numbers to another offset.
Finding and Replacing Symbols
It is possible to perform a replace on 'Symbol Names' within a program, but this only updates the program, so
that the new name is inserted as the operand. The replacement within the program does not affect the
underlying symbol definition.
When a symbol name is updated in the symbol table, the programs using the symbol will also be updated to use
the new name.
Note: It is not possible to change the definition of a symbol from within a program. i.e. A symbol's
comment or name cannot be changed unless the replace is happening within the symbol table.
Imorovements to Global Replacement Operation
Changes between normally open contacts and normally closed contacts can be performed for specified addresses
using the
Change All operation.
If Change All is selected from the Edit menu and a checkmark is placed in the checkbox for Invert open/close
bit before performing a global replacement for the PLC, all specified operands that are normally open contacts
will be changed to normally closed contacts and all normally closed contacts will be changed to normally open
contacts
.
Note: If the check box for symbols (including I/O comments) is cleared before an address is replaced
globally, the symbols table and I/O comments will not be changed and only addresses in the
ladder program will be changed. If the check box for symbols (including I/O comments) is
selected before an address is replaced globally, the replacement operation will be the same as
the previous version of the software (version 3.0).
Finding and Replacing Symbols in the I/O Comment View
Symbol comments can be searched and replaced on the I/O Comment view. Use the I/O Comment view to
replace comments of TIM/CNT instructions (for both BOOL and CHANNEL types) and to update those
changes to all symbol tables and programs.
F3 Searching
When the search dialog is closed search is possible using the F3 key. The same search criteria is used except
that the search will never progress beyond the scope of the focus. Hence, a single view focus will never open
another view whereas if the scope is a program level then the search will continue for the scope covered by that
of a normal search.

Each window or object in CX-Programmer has associated Properties that can be displayed. The method of
displaying the tool is the same.
