Ladder Editor
To Quick Edit ladder logic
• In the ladder logic, click on a rung and type instruction mnemonics separated by semicolons, and then press ENTER.
The instructions specified by the mnemonic string you entered will be inserted, in
order, on the rung. You can enter mnemonics followed by variable names if you
want to assign instruction parameters while Quick Editing.
Example: Add a Normally Open Contact (NO) instruction followed by a Coil
(OUT) instruction and assign the variables MySwitch and MyCoil to these
instructions respectively.
NO MySwitch; OUT MyCoil
Working with the ladder editor - Online
With the ladder editor you can go online to a ladder program being run by the
Controller (page 55). While online, you can view the power flow through the
ladder logic and watch data values change in real time. You can also edit the
ladder program, just as you would while offline, with the following restrictions:
■
Labels, subroutines, and actions cannot be deleted while online.
■
Only one rung can be changed before writing the changes to the Controller.
The following picture illustrates the ladder editor while online to the Controller.
Online status is indicated
by the color of the
target icon.
Lightning bolts in each
corner indicate the
Controller’s status and
change to reflect fault
conditions.
New or edited rungs are
indicated with alternate
color bold lines until
you Write Changes.
Power flow is indicated
with bold colored lines.
Data values are
displayed in real time
as they change each
scan by the Controller.
Use the Data Watch to
view or set data values
for any variable in your
project.
