Understanding the Resources of Your Drive

Publication 1336 FORCE–5.18 ––March, 1999

In addition, each function block type also has parameters that are
called I/O nodes associated with them. When you use a function
block, the I/O nodes are created within the system. These I/O nodes
are removed from the system when that function block is no longer
in use. In all, the function block software can allow a total of 799
new node parameters in addition to the 493 linear parameters. You
can modify and manipulate the node parameters to meet the needs of
your particular application.

Using the function block node parameters requires that you create a
function block application. A function block application is a
combination of the function blocks that you want the drive to
execute in the order that you want them executed. Each function
block within an application is called an event, and you may have up
to 128 events in your application. To create your application, you
need to use a PC with the DriveTools’ DriveBlockEditor software, a
Bulletin 1201 Graphic Programming Terminal (GPT), or a PLC.

Once you have created your function block application, you need to
download it to the drive where it is compiled into a function block
program. When you download and compile the application, the
ControlNet Adapter Board creates the functionality and data sets
within the drive. Once the application is running, each event is
executed with a 20 millisecond task interval.

Note: You can only have one function block application executing
in the drive at any given time.
