Communicate over Networks
Chapter 4
DeviceNet Communication
To communicate and exchange data with safety I/O devices on DeviceNet
networks, you need a 1756-DNB module in the local chassis.
For information on how to install your 1756-DNB module, refer to the
ControlLogix DeviceNet Scanner Module Installation Instructions,
publication
The 1756-DNB module supports communication with DeviceNet Safety
devices and standard DeviceNet devices. You can use both types.
These products are used with the DeviceNet networks and 1756-DNB
module.
DeviceNet Connections for Safety I/O Devices
To access safety I/O devices on DeviceNet networks, add a 1756-DNB to the
I/O Configuration tree of the GuardLogix controller project.
Safety I/O devices on DeviceNet networks are added to the project under the
1756-DNB module, as described in
Replace CIP Safety I/O Devices
. When you add a safety I/O device, the Logix
Designer application automatically creates controller-scoped safety data tags
for that device.
