Limit To options
When you click
Limit To
on the Find
dialog box, the Limit To
section of the dialog box expands, displaying options specific to each item. The following table describes the manner in which the Limit To
option chosen impacts which items are found.If you choose this item | Search will find |
Text Only | Only the text specified in the Find What field. |
References to Exact Tag and Its Members | References to the tag specified in the Find What field, in addition to any more specific references. For example, if you enter the tag t1.ACC, the search finds t1.ACC and any references to bits of the ACC member (for example, t1.ACC.0 or t1alias.ACC.0). If the tag you entered in the Find What field is an alias chain, then the search finds all references to the equivalent specific references also. |
References to Tag | References to the tag specified in the Find What field, as well as any more specific or more general references to the tag. For example, if you enter the tag t1.ACC, the search also finds t1.ACC.0 or just t1.If the tag you entered in the Find What field is an alias chain, then the search finds all references to the equivalent general or specific references also. |
Forces | References to any forced tags. For Sequential Function Chart routines, the search finds all Forced Transitions and Disabled Simultaneous Branch Paths as well. If you choose this option, the Find What field is disabled and references in the Find What field are not included in the search. |
Edit Zones | Logic inside routines that has been online edited, but not assembled. For Ladder Logic routines, the search will find the rungs with edits. For Sequential Function Chart, Function Block Diagram and Structured Text routines, the search will find the beginning of the routines with edits. If you choose this option, the Find What field is disabled and references in the Find What field are not included in the search. |
Active SFC Steps and Actions | All active Steps, Actions, and Stops within existing Sequential Function Chart routines, as well as any steps or stops in the Reset state. If you choose this option, the Find What field is disabled and references in the Find What field are not included in the search. |
Shorted Branches | References in any shorted branches in the ladder routine. If you choose this option, the Find What field is disabled and references in the Find What field are not included in the search. |
Within Add-On Instruction routines, select
Text Only
or References to Tag
(choosing References to Exact Tag and its Members
is the same as References to Tag
) because there are no aliases, forces, edit zones, or active Sequential Function Chart elements. However, all other choices are available because you can choose to include routines external to the current one in the search. Once you choose an option, the Logix Designer
application remembers your last choice. The default is Text Only
.InOuts can reference aliases and forced tags, but the search takes place on the definition, not the specific data context. So, aliases and forces are not found within Add-On Instructions logic.
