Add a Block
Blocks are defined by the field
device manufacturer and
described in the DD files.
There are three classes of blocks:
R – Resource Block
T – Transducer Block
F – Function Block
Only function blocks have ports that are used to transfer data to and from the
block:
• Ports on the left of the function blocks are inputs.
• Ports on the right of the function blocks are outputs.
For detailed descriptions and uses of each block, refer to the user manual of the
field device.
Follow these steps to add a block.
1. To add (instantiate) a block, right-click in the window and choose New
Block.
A list of all available blocks for the specific device appears.
2. Choose the block that you want to use.
The block appears on the screen.
