Peer-to-peer Safety Communication
Peer-to-peer safety communication between safety-enabled controllers is possible via the
EtherNet/IP™
network or across the ControlLogix®
backplane. The controllers can control and exchange safety data with safety I/O devices on an EtherNet/IP™
network, via the onboard Ethernet ports or EtherNet/IP™
bridges.
IMPORTANT:
A remote
GuardLogix®
or Compact GuardLogix®
controller that has firmware earlier than revision 28 cannot consume data from a GuardLogix®
5580 or Compact GuardLogix®
5380 controller. Older consumer controllers must be updated to at least to firmware revision 28, or use a dedicated, separate EtherNet/IP™
module in the same chassis as the GuardLogix®
5580 controller, making a connection for produced/ consumed tags that bridges through the Logix backplane. See Knowledgebase Article .Peer-to-peer Communication via the EtherNet/IP Network
TIP:
Peer-to-peer safety communication between two safety-enabled controllers or I/O modules in the same chassis is also possible via the backplane.
