Rules for Finding
Symbols may only have their details replaced when in the symbol table. An attempt to replace a symbol name or
address whilst in the Ladder View will result in the generation of a new contact that will appear in error. Symbol
comments may only be replaced whilst in the Symbol Table, and so the option to replace comments are not
allowed by disabling the replace buttons.
When doing a text search information will only be found in a step, regardless of whether it is being filtered from
the view or not. For example in the Symbol Name is not being displayed but the symbol is found to have a
match, the symbol will still be highlighted.
Tree searching is the same as a normal search, in so much as the same rules are applied to Address, Value and
Text searching as if carried out in a single view. For each branch of the tree the following search criteria is
applied.
♦ Find in Project: finds occurrences in all PLC’s, Symbol Tables and Programs.
♦
Find in PLC: finds occurrences in all Symbol Tables and Programs.
♦
Find in Global Symbol Table: finds occurrences in this Global Symbol Table only.
♦
Find in Program: finds occurrences in Local Symbol Table and all Sections.
♦
Find in Local Symbol Table: finds occurrences in this Local Symbol Table.
♦
Find in Section: finds occurrences in this Section.
♦
Find in area: finds occurrences in I/O Comment view.
Other find features supported include: Multi-byte character sets (MBCS), Multiple instances in a rung,
Statement List (SL) – as standard Ladder View and while online to a PLC.
Find
The Find dialog allows various types of search to be carried out inside a window, from the project workspace
and while online to a PLC. Select
How to Input pushbutton to show examples.
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 list. This allows a choice to be
made of the type of item being searched/replaced. The choices are as follows:
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).
Symbol Names – searches for names of program symbols (local and global).
All (strings) – searches all the search targets, including addresses, constants, numbers,
mnemonics, variable names, I/O comments, rung comments, and other comments. (CX-
