Text can be added as comments to the Ladder program either as notes that are not compiled or as rung
comments that are compiled with the code (setting the
Use Comment Instructions property of a PLC). Rung
comments are typically used for introducing and explaining chapters of code.
Comments can also be entered against symbol names and addresses via the elements associated edit or
properties dialogs. Symbol comments are downloaded to the Memory Card, if one is present or to allocated EM
memory.
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 grayed 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.
Setting Multiple I/O Comments for a Single Address
Multiple I/O comments (up to 16) can be registered for a single address symbol. By selecting the comment
group to be displayed from the multiple I/O comment groups (up to 16 groups), the I/O comments on the ladder
diagram screen can be changed all at once. This function allows multilingual development of a single program
or attachment of comments according to the development step.
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.
