The default values reflect the maximum number of read/write words.

You can change the I/O data size for a module by reducing the number of words
mapped into the adapter module, as shown in optimal sizes.

Optimal sizes

are the settings that provide optimal data to and from the I/O

module. You need a software configuration tool to change

the size. If you are using the Rockwell Automation 1785-PFB/B coprocessor as a
master, you must use the Rockwell Automation PROFIBUS Manager Software
configuration tool. Because the FLEX I/O adapter is compatible with any master,
you can use any comparable configuration tool available on the market.

The optimal settings provide the fastest network time by only mapping read and
write words used by the I/O modules. If you reduce your data sizes to only
include optimal data, you can only change your configuration data with a
software tool. If you must change configuration information on an optimal basis,
your data size must be large enough to include the necessary words.

If you are using PROFIBUS Manager Software to configure your adapter, refer to
your PROFIBUS Manager Software User Manual, publication 1785-6.5.20 for
more information.

For additional information on FLEX I/O modules, refer to the following
publications.
