15-2 Using POINT™ I/O Modules on a DeviceNet Network
Choose a Connecting
Device
To choose the device that connects your POINT I/O modules to the
DeviceNet network, consider the following:
• total number of devices on the network
• type of devices on the network
• topology and length of the network
• current requirements of the POINT I/O modules

main DeviceNet network
• Each I/O module uses
an address on the
main DeviceNet
network.
• Total current
requirements of the
I/O modules must be
1.3A or less.
• Consolidates the I/O
module into a single
address on the main
DeviceNet network.
• Total current requirements
of I/O modules can be
greater than 1.3A.
The subnet lets you:
• connect other types of
DeviceNet devices to the
subnet
• Place devices beyond the
limits of the main
DeviceNet network
If you are also using a
POINTBlock I/O
module, connect your
other POINT I/O
modules to that
module.
