This pane displays IO Map data in a grid, where IO Maps are grouped into tabs according to the the protocol type of their associated data connector, such as CSV or Excel. Under the relevant tab, you can see a specific row for each IO Map. You can use the standard grid functions to manage the items or layout of the tabs. For more information, see :ref:`screen.grid.functions`.

On this pane, you can view IO Map data or update your IO Map configurations (adding, updating or deleting IO Maps) as required. For more information about IO Map configurations, see :ref:`conf.extd.iomaps`.


Review Trends
-------------

The Trends functionality allows you to visualise the historical values of the raw tag as compared to the filtered tag for a selected IO Map. 

To review trends, follow the steps below:

1. On the **IO Maps** pane, select the required IO Map.
2. Click the |trend| icon in the **Action** column of the relevant IO Map.
3. Review the charts in the **Quick Trend** panel that appears on the right side of the screen. On this panel, you can also adjust the period, the refresh rate and display or hide the legend.
