DeviceNet Communications Module for NT31/NT631
Network Configuration Options
Two factors determine how many operator interface terminals
can be used on a DeviceNet network:
•
•
The model of the DeviceNet master and number of devices on
the network determine how much Remote I/O is available. If
Remote I/O space is limited, more NT31/631 can be placed on
the network by reducing the number of the input and output
words reserved by the NT-DRT21 unit. Refer to the following
charts.
Weighing the options
DeviceNet I/O modules on the network use up Remote I/O
capacity, reducing the number of NT units on the network. A
DeviceNet Configurator increases the capacity by deactivating
explicit messaging and freeing up reserved memory, increasing
available Remote I/O capacity and allowing more NT units to be
connected to the network. However, explicit messaging can
access 120 additional words in the NT memory area.
Deactivating the explicit messaging eliminates this option.

Calculating the Number of NT31/631 Units
The following examples illustrate the impact of Remote I/O availability and use of a configurator.
