These products are used with the DeviceNet networks and 1756-DNB module.
DeviceNet Connections for CIP Safety I/O Modules
To access CIP Safety devices on DeviceNet networks, add a 1756-DNB to the
I/O Configuration tree of the GuardLogix controller project.
CIP Safety I/O modules on DeviceNet networks are added to the project under
the 1756-DNB module, as described in Chapter
5, Add, Configure, Monitor,
and Replace CIP Safety I/O. When you add a CIP Safety I/O module, the Logix
Designer application automatically creates controller-scoped safety data tags for
that module.

Standard DeviceNet Connections
If you use standard DeviceNet I/O with your GuardLogix controller, you need to
allocate two connections for each 1756-DNB module. One connection is for
module status and configuration. The other connection is a rack-optimized
connection for the DeviceNet I/O data.
