The following tasks are used when you assign blocks to instrument loops or tags.
Use this procedure to associate a loop block with one or more loop numbers. You can
only assign a loop block if the loop that you selected does not have any instrument
blocks assigned using the manual block assignment method. Such blocks are shown under
the loop tags as 
. The software, however, does not prevent you from assigning a loop block to the loop
is the loop tags have instrument blocks assigned using the automatic block assignment
method. Such blocks are shown under the loop tags as 
. After associating a block with a loop, when generating a loop drawing, the software
always uses the loop block and ignores instrument blocks this loop might contain.
Associate Instrument Blocks Automatically (via Instrument Type)
In an instrumentation design setup with a very large number of control loops, similar tag numbers are represented repeatedly using the same drawing block, the only difference being the data that is retrieved by the macros in the drawing. Therefore, instead of having to associate each block with an instrument manually, you can use this procedure to associate typical blocks with a specific instrument type.
Change the Block Assignment Method from Automatic to Manual
This procedure enables you to change the assignment method of instrument blocks from automatic to manual. Blocks assigned to tag numbers using the manuals block assignment method become available for selection in the Generate Loop Drawings dialog, where you can set the software to generate loop drawings only for those loops that use a specific manually assigned instrument block.
Associate Instrument Blocks Manually
You can manually associate one or more blocks with tag numbers belonging to the same loop number. In this case, that the software draws blocks after you select a loop number in the Domain Explorer.
This procedure enables you to update block assignments that might have been changed during your <plant> life cycle. You can update block assignments in batch mode, for one or more instrument tags belonging to the same loop or to a group of loops.
Copy Associated Blocks to Other Instrument Tags
Use this procedure to copy one or more blocks that are associated with a particular instrument to other instrument tags displayed in the Domain Explorer.
Copy Automatically Assigned Blocks to Tags of Other Loops
Use this procedure to copy blocks from all instrument tags of a specific loop to all
instruments of one or more target loops. The software only copies those blocks that
are assigned to the source loop instruments using the automatic block assignment method.
In the Domain Explorer, these blocks are indicated with the icon. The software validates the instrument tag assignments and the drawing type
of the target loops before copying the blocks.
Assign an Instrument Block to a Drawing Page
Use this procedure to assign a CAD drawing block to a specific page in the generated
loop drawing when the loop drawing multi-page drawing or multi-drawing. You must perform
this procedure if the drawing block is assigned to the loop instrument using the automatic
block assignment method. Such blocks are shown under the loop tags as .
Dissociate Blocks from Instruments
Use this procedure to dissociate blocks from instruments belonging to the same or different loops.
Specify Border and Logo Blocks for Loop Drawings
This procedure allows you to set Smart Instrumentation to use a specific border block and logo block every time you generate a CAD loop drawing. Blocks that you set as default general blocks must belong to the shipped general block types, that is, Border and Logo. You define and manage blocks in the Drawing Block Types folder of the Domain Explorer.
Assign General Blocks to All Loop Drawings via Instrument Type
Use this procedure to assign user-defined general blocks to a specific instrument type. This procedure allows you to display general blocks in all loop drawings automatically if the source loops have tags belonging to the instrument type to which you assigned the blocks. The software displays such blocks in addition to the default border and logo blocks that you specify on the Default General Blocks dialog.
