5–7 How Communication Takes Place and I/O Image Table Mapping with the DeviceNet Adapter
Publication 1794ĆUM016B-EN-P - August 2002
Each I/O module has default values associated with it. At default,
each module will generate inputs/status and expect
outputs/configuration.

Factory defaults are the values assigned by the adapter when you:
•
first power up the system, and
•
no previous stored settings have been applied.
For Pulse Counter modules, the defaults reflect the actual number of
input words/output words. For example, for the Pulse Counter
module, you have 10 input words, and 5 output 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 “real
time sizes.”
Real time sizes are the settings that provide optimal real time data to
the adapter module.
The Pulse Counter modules have 15 words assigned to them. This is
divided into input words/output words. You can reduce the I/O data
size to fewer words to increase data transfer over the backplane.
For information on using DeviceNetManager software to configure
your adapter, refer to the DeviceNetManager Software User Manual,
publication 1787-6.5.3.
