controller control and exchange safety data with CIP Safety I/O
modules on a DeviceNet network.
DeviceNet Communication via a 1756-DNB Module
ControlNet Network
The 1756-CN2 or 1768-CNB module lets the GuardLogix controller
produce and consume safety tags over ControlNet networks to other
GuardLogix processors or remote CIP Safety I/O networks.
TIP
Peer-to-peer safety communication between two 1756
GuardLogix controllers in the same chassis is also possible via
the backplane.
