amended by explicitly selecting the On-line Edit feature.
It is usual to have the PLC operating in Monitor mode while using on-line editing functions. On-line editing is
not possible in Run mode.
Use the following procedure to edit the program on-line.

Attaching Comments
An attached comment is a comment associated with an element of a program (i.e. contact, coil or instruction).
The comment is entered through the Properties dialog box of the element by selecting the Properties option
from the context menu of the item.
When a comment has been entered against an element, a circle will appear at the top-right corner of the element.
This circle contains a number that uniquely identifies the comment within the rung. The comment itself will
appear to the right of the circle for output instructions (subject to the chosen ladder-information options), or it
will appear in the Rung's Annotation List.

1. Select the PLC object in the project workspace.
2. Select the Toggle PLC Monitoring button from the toolbar.
3. As the program executes, data and power-flow can be followed in the Ladder program;
for example, connections are selected and values are incremented.
Individual PLC data elements can be monitored via the Watch Window. This window allows
monitoring of addresses from multiple PLCs at the same time.
The values are monitored in a format according to the data-type of the symbol that is being
used for the operand, or the data-type of the instruction operand itself. To always monitor in a
single, hexadecimal format, turn on the Monitor In Hex option from the toolbar.
1. Select the rungs to be edited by dragging the mouse and selecting the required rungs.
2. Select the Compare with PLC button from the toolbar to ensure that the edited area is

3. Select the On-line Edit Rungs button from the toolbar. The background to the rung
changes to show that it is now an editable area. The rungs outside this area cannot be

toolbar. The editing is checked and transferred to the PLC.

once more. The on-line edit can be cancelled at any point prior to committing the
changes by selecting the Cancel On-line Edit button from the toolbar.
Table, or in I/O Comment View. If I/O comments have been changed when online editing is
ended, a confirmation message will appear asking if the symbol table file should be transferred
to file memory in a CS-, CJ-, CP-, CVM1, or CV-series PLC or to the I/O comment area in the
allocated UM (user memory) in a C-series PLC.
Symbol table names and addresses cannot be changed during online editing.
I/O comments with symbol names cannot be transferred to the I/O comment area in UM (User
Memory) in C-series PLCs.
