Note:
Unlike the Ladder programs for most PLCs, the Ladder programs for CV-series PLCs show a
step offset number for the rung comment (this is because this series has a rung comment
instruction).
I/O Comment View
In the I/O Comment View, you can enter comments by addresses of selected area type. This view is for users
who prefer to use addresses and comments when creating a ladder program. Therefore, for users who use
symbols for ladder programming, Symbol Table will be preferable to enter comments. If there are any
comments already defined in the symbol table, these will also be displayed in the I/O Comment view. When
either I/O Comment or Symbol Table view, is edited, the changes will be reflected in the other view. This view
can only be edited whilst offline. The pre-defined symbols will be greyed out and cannot be edited.
Use the following procedure to edit the address comments on I/O Comment window.
1, 2, 3…
1. Open the I/O Comment view by selecting the
I/O Comment
button from the toolbar
Edit
option.
2. Select the appropriate memory area in which the comments are to be edited from the
Area
Type
.
3. Enter an address in the
Start Address
and press
Enter
key.
4. With the selected comment now highlighted click the right mouse button and select the
appropriate function. i.e. Edit, Cut, Copy, Paste or Delete. To move to another comment
field, enter the appropriate
Start Address
and press
Enter
or use the scroll function.
Note that when comments are deleted, symbol(s) defined without a name will also be
deleted from the symbol table. For symbol(s) defined with a name on the symbol table,
only comment will be deleted.
Note that when editing comments of
TIM/CNT Instructions
, use I/O Comment view in
order to link comments for all BOOL, CHANNEL, and NUMBER type of TIM/CNT
instructions. When TIM/CNT comments are entered in this view, the comments for all
types of the TIM/CNT instruction will display the same comments.
Block Programs
CX-Programmer supports the ability to enter a rung in statement list format – useful for block programs.
The statement list view of a rung can be used instead of the Mnemonics editor but does not support program
monitoring.
Use the following procedure to edit a rung in statement list format.
1, 2, 3…
1. Select a rung. Choose the
Show as Rung Statement List
option from the context menu
of the rung.
The rung is shown in statement list format.
Move the cursor to a line on the list, and press ‘Enter’. It is then possible to edit the
instructions. Move up and down with the cursor keys, and amend the text.
There is no restriction on the length of a statement list program apart from that which
Windows may apply.
2. Entries in the statement list block are compiled continuously and the rung may be shown
in error (the error bar on the rung margin).
