Using the Status Chart to Monitor and Modify the Current Values of the Program

You can use the Status Chart to monitor or modify the current values of any I/O points or
memory locations. Reopen the Status Chart window, if necessary, and select the menu
command Debug

Chart Status On, as shown in Figure 3-23. As you switch inputs on or

off with the CPU in RUN mode, the Status Chart shows the current status of each element.

To view the current value of the elements in your program, click the Single Read
button

or the Continuous Read button

in the Status Chart window.

To stop the reading of status, click the Stop button

in the Status Chart window.
