Variable Status
The Variable Status page allows you to view any of the I/O or memory data in your CPU.
You can enter a direct address (such as I0.0), a PLC tag name, or a tag from a specific data
block. For data block tags, you enclose the data block name in double quotation marks. For
each monitor value you can select a display format for the data. You can continue entering
and specifying values until you have as many as you want within the limitations for the page.
The monitor values show up automatically and refresh by default, unless you click the "Off"
icon in the upper right area of the page. When refresh is disabled, you can click "On" to re-
enable automatic refresh.
With the "admin" log in, you can also modify data values. Enter any values that you wish to
set in the appropriate "Modify Value" field. Click the "Go" button beside a value to write that
value to the CPU. To modify a variable of data type STRING, you must enclose the string in
single quotation marks. You can also enter multiple values and click "Modify All Values" to
write all of the values to the CPU.
