Edit Functions in Runtime Online Editing
During a runtime online editing session, the processor is executing ladder logic. The
edit zone markers tell the processor that changes exist, but the changes are not
executed until you test the edits.
Deleted and replaced (modified) rungs are not removed from the program and
inserted rungs are not executed until you assemble the edits.
Edit Functions in Program Online Editing
During a program online editing session, the processor is not executing ladder logic.
This mode is like the offline editing mode. Note that if a runtime online editing
session was performed prior to entering the offline editing mode, edit marked rungs
(I, IR, and D) appear in the program.
If you perform a program online edit, once you accept or delete the rung, the edits
take effect immediately and the power rail is displayed as a solid line. If you edit a
rung with edit zone markers, the markers are removed when the rung is accepted.
Online Editing Screen Display
Online editing functions consist of inserting, replacing, and deleting rungs in an
existing ladder program. The editing display for SLC 5/03 and SLC 5/04 processors
is different from the SLC 5/01 and SLC 5/02 processors:
•
The status line provides diagnostic information sent by the processor.
•
New edit zone markers (Replace and Delete) indicate the type of rung changes.
Edit Zone Markers
While programming online edits, edit zone markers appear on the power rails,
indicating the type of ladder program edit. Edit zone markers include:
•
I — indicates the rung is to be inserted
•
R — indicates the rung is to be replaced
•
D — indicates the rung is to be deleted
