Licensed Blocks
From the Help menu, choose About to determine how many blocks you have
licensed.
The licensed block information appears below the Rockwell Software copyright.
The Main window contains a counter in the lower-right corner that lets you see
how many blocks you have in use.
TIP When choosing an RSFieldbus license, keep in mind that a typical device
requires a minimum of three blocks (Resource, Transducer, and process
control) with an average of five blocks used. For example, a 64-block
RSFieldbus license will support approximately 21 devices. Any device
that requires more than three blocks will reduce the number of
supported devices.
