CX-Programmer _Page 33
By moving the cursor to an address in the ladder diagram and selecting Check usage including unused , the usage
list (with comments) can be displayed starting with the selected address (CX-Programmer Ver. 4.0 or later).
This function enables the cross references to be checked for the address directly from the ladder display instead
of from the cross reference report.
By selecting Duplicate usage in programs in the cross reference report function, a list can be checked for any
bits/words that have been allocated an address already being used by another task (see note; CX-Programmer
Ver. 4.0 or later). This function can be used to easily check whether the same address is being used by another
task (programmer) when two or more programmers are creating multiple tasks.
Note: Cyclic tasks only (interrupt tasks not included).
A cross-reference report can be printed. Use the following procedure to print a cross-reference report.
1, 2, 3… 1. Select the Cross-Reference Report button from the toolbar to open the Cross-Reference
Report.
2. Generate an appropriate cross-reference report.
3. Select the Print pushbutton. A standard Microsoft Windows Print dialog defines printer
settings and allows print parameters to be entered.
Address Reference Tool
The Address Reference Tool shows how and where a PLC address is used within the program set of a PLC.
Use the following procedure to use the Address Reference Tool.
1, 2, 3… 1. Open a Ladder program by double-clicking the program object in the project workspace.
2. Select a cell in the Ladder program.
3. Select the Address Reference Tool button from the toolbar. The Address Reference
Tool window is displayed in the Diagram Workspace. The Address Reference Tool
displays a list of references made to the address selected in the Ladder program.
4. With the Address Reference Tool still open, another selection can be made in the Ladder
program; the Address Reference Tool is refreshed accordingly.
The Address Reference Tool is displayed in front of other windows. Only one Address Reference Tool can be
opened at a time. The window can be ‘docked’ within the main CX-Programmer window.
Note: It may be necessary to show the address reference tool in order to use the commands Go to
Next Output , Go to Next Input and Go to Next Address Reference , depending upon the
diagram options chosen (see page 32).
