Monitoring Programs Section 10-2
10-2-2 Watch Window
The Watch Window of the G9SP-series Controller can be used to increase the
efficiency of debugging.
Monitoring I/O Tag Values
You can register any I/O tags to the Watch Window to monitor the ON/OFF
status in the Watch Window. This is convenient for monitoring changes in the
values of I/O tags that are located on different pages, as shown below.
Example: Simultaneously Monitoring I/O Tags on Different Pages
To check the value of an output tag on page 2 when an input tag on page 1
changes, the output tag can be registered to the Watch Window so that the
status of both tags can be monitored while displaying page 1.
Analysis Displays for Related I/O Tags
With the G9SP Configurator, the I/O tags that are related to I/O tags that are
registered to the Watch Window can be analyzed. As shown in the following
example, input tags related to an output tag are displayed, and then the output
can be checked to make sure it turns OFF when one of the input tags turns
OFF.
