3. The PLC name , the symbol name , and/or the data type/format may be selected on the
Edit Dialog . To display this dialog, double-click on the cell of the Watch window, or
select Edit from the context sensitive menu. Select the Browse pushbutton to locate a
symbol, if required.
Note that a local symbol may be entered by typing in the program and symbol name,
separated by a '.' character (this symbol 'path' is also shown in the watch window for local
symbols).
4. Select the OK pushbutton to complete the operation. Select the Cancel pushbutton to
abort the operation.
The PLC name is added to the Watch window. During program execution, the changing value of this address is
displayed. Values can be set in this window to a specific value to test program execution. Watch items can be
monitored either on the
Watch window (for any number of watch items) or on the Set New Value dialog (for one
watch item). On the Set New Value dialog, the value can be monitored in Binary number (except for data type:
BOOL/ASCII and area type TIM/CNT). Each bit can be Force Set / Reset / Cancel and Set / Reset .
Array Variable Monitoring
To monitor an array variable in the Watch Window, it is possible to register the variable by dragging/dropping it
directly from the symbol table to the Watch Window. All elements of the array variable can be monitored in the
Watch Window.
Displaying PVs of Addresses in the Watch Window Sheet in Binary
The watch sheet includes a column that allows the PVs of addresses to always be displayed in binary regardless
of the settings specified in
Data Type/Format . 16 BIT (Binary, Channel) can also be selected from the Data
Type/Format Options, allowing values to be displayed in binary, even if the Binary column is hidden (except in
the Timer/Counter Areas). (CX-Programmer Ver. 4.0 or later.)
Changing the PVs for DM/EM Areas in Bit Units
While online, when the binary display is selected in the Set New Value dialog that is displayed when the address
in the watch window is clicked, the DM/EM Area data can be changed into PVs in bit units (CX-Programmer
Ver. 4.0 or later).
Pause Monitoring
When pause monitoring is taking place, items in the watch window are monitored as normal until the trigger
point is reached or the user triggers manually. At this time, the monitoring is stopped and the value field of all
items within the watch window is cleared. When either monitoring or pause monitoring is re-started, the value
field of all the items within the watch window is refreshed with the current value.
Dragging and Dropping Items
Symbols, ladder elements and symbol tables (from the project tree view) may be dragged and dropped into the
watch window. These items may be dragged individually or in block form. It is not possible to drag elements
into the watch window from the mnemonic editor, or entire sections from the project tree view. Items may not
be dragged from the watch window i.e. it is only a drag and drop target and not a source.
