EtherNet/IP Communication Example
This example illustrates the following:
• The controllers can produce and consume standard or safety tags between
each other.
• The controllers can initiate MSG instructions that send/receive standard
data or configure devices.
(1)
• The EtherNet/IP communication module is used as a bridge, letting the
safety controller produce and consume standard and safety data.
• The personal computer can upload/download projects to the controllers.
• The personal computer can configure devices on the EtherNet/IP
network.
Figure 12 - EtherNet/IP Communication Example
EtherNet/IP Connections for CIP Safety I/O Modules
CIP Safety I/O modules on EtherNet/IP networks are added to the project
under the EtherNet/IP communication 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.
(1) GuardLogix controllers do not support MSG instructions for safety data.
