Use the following procedure to execute a find.
1, 2, 3… 1. Select an object in the project workspace to begin the search.
2. Select the Find button from the toolbar or select the Find option from the Edit menu.
3. Select the required Look At entry from the drop down menu. This allows a choice to be
made of the type of item being searched/replaced. The choices are as follows:
Bit Addresses – searches for addresses within program operands and symbols in the Bit
unit. No period is needed to enter an address. This will not find CHANNEL addresses
and values set into operands (such as ‘&’ or ‘#’ operands), but will find TIM/CNT
numbers (by setting a T/C address).
Addresses - searches for addresses within program operands and symbols. This will not
find values set into operands (such as ‘&’ or ‘#’ operands), but will find TIM/CNT
numbers (by setting a T/C address).
Values - searches for numeric values within program operands and
NUMBER
data-type
symbols. This also finds timer/counter numbers in
TIM/CNT
instructions.
Mnemonics - searches through a program by examining the entire statement list line of
each step. Using this, it is possible to search for a combination of a particular instruction
and operand together. It is possible to change the instruction.
Symbol Names - searches for names of program symbols (local and global).
Symbol Comments - searches for comments of program symbols (local and global).
Program Comments - searches for comments within a program. This includes the
comment made against a rung, or its set of annotations (comments made against a
particular element in the program, or comments from comment boxes in project files
from previous versions of CX-Programmer).
4. Enter the text or item to be found in the Find What field.
The pull-down list on the Find What field can be used to enter the contents used for
previous find operations.
5. Select the search criteria from the available options.
6. Select either the PLC or Current view to set the scope of the search. Click Find Next
to begin the search. The result of the search is displayed in the box below Scope . This
displays the match found, and where in the string the it was found. The view also
changes to where the result is located. Select
Cancel to abort the operation.
7. Click Report instead to produce a report of all occurrences of the search. Once this
report is generated, shown on the ‘Find Report’ tab of the output window, it is possible to
move to a particular occurrence by double-clicking the report line.
Note: During a search matches are described by a context descriptor string above the
lower scope box. The information contained in this string will include Step, Operand,
and Step Mnemonic information.
