Displaying Graphics

To instantiate a block:
1. Display the Live Device List; see page 4-7.
2. Double-tap a device.
3. Double-tap Advanced.
4. Double-tap Instantiate Block.
5. Tap the type of block that you want to add to the device.
6. Tap OK to add the block to the device. Tap CANCEL to exit the window without
adding a block.
7. When the warning message appears, tap YES to instantiate the block, or NO to
cancel the operation.
Deleting Instantiated Blocks
The Delete Block menu lets you delete instantiated blocks from a fieldbus device; you
cannot delete permanent blocks. You can delete only one instantiated block at a time,
and the Actual mode in the device must be set to OOS. If the Delete Block menu item
is selected and no blocks have been instantiated in the device, an error message
appears. After a block has been deleted, the window is refreshed and it does not
display the deleted block.
To delete an instantiated block:
1. Display the Live Device List; see page 4-7.
2. Double-tap a device.
3. Double-tap Advanced.
4. Double-tap Delete Block.
5. Tap the block that you want to delete from the device.
6. Tap OK.
7. When the warning message appears, tap YES to delete the block, or NO to cancel
the operation.
NOTE
Some devices restart after a block is instantiated or deleted, causing a loss in
communication between the 475 Field Communicator and the device. After the device
and 475 Field Communicator resume communication, the Live Device List appears.
The F Fieldbus Application offers graphical views of device data by using
OUNDATION
the enhanced Electronic Device Description Language (EDDL) technology. Device
data can be presented as images, charts, and graphs. These options appear as items
in the Online menu and its submenus. The placement of the Graphics options in the
menus varies from device to device because it is determined by the device
manufacturer.
To view the graphical representations, you need a device using an enhanced device
description. Only devices using an enhanced EDDL device description offer graphical
representations of data. See Appendix C for more information about the Graphics
functionality.
