Fieldbus Functionality 4-19
Instantiate Blocks
The Instantiate Block menu lets you add function and
transducer blocks to a connected device. This menu
item appears only if the fieldbus device contains
instantiable block types. After a block has been
instantiated, the view displays the new block. The Actual
mode of the new instantiated block will be set to OOS.
To instantiate a block:
1. Display the Live Device List; see page 4-9.
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 screen without adding a block.
7. When the warning message appears, tap YES to
instantiate the block, or NO to cancel the operation.
NOTE
You cannot instantiate or delete blocks when, at a
minimum, any of the following hosts/linking devices are
detected on the segment: Rosemount 3420, DeltaV,
Ovation, Allen-Bradley, Honeywell Experion PKS, or
Yokogawa Stardom. To instantiate or delete blocks, use
the host system or remove the device from the segment
and connect it directly to the 375 Field Communicator.
Delete 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 will appear. After a block has been
deleted, the screen is refreshed and it does not display
the deleted block.
