Dual-IP Mode
Out-of-the-box, the
EtherNet/IP™
mode is Dual-IP mode.
IMPORTANT:
Parallel Redundancy Protocol is not currently supported.
IMPORTANT:
With
ControlLogix®
5590 controllers, the Ethernet ports on the controller itself are labeled 1 and 2. In programming and communication software, the ports are described as A1 and A2Dual-IP mode lets you connect ports 1 and 2 to separate networks. In this mode, port 1 can connect to an enterprise-level network or a device-level network. Port 2 can only connect to a device-level network.
In this mode, each port requires its own network configuration.
You must avoid overlapping IP address ranges when you configure the Ethernet ports in Dual-IP mode. For more information, see Overlapping IP Address Ranges.
The following figure shows a controller using Dual-IP mode with connections to an enterprise-level network and a device-level network.
Controller in Dual-IP Mode with Enterprise-level and Device-level Connections
The following figure shows a controller using Dual-IP mode in with connections to separate device-level networks, including a DLR network.
IMPORTANT:
If a controller is using Dual-IP mode, it can connect to a DLR network topology through a 1783 Ethernet tap or a
Stratix®
switch that supports DLR. Controller in Dual-IP Mode with Device-level Network Connections Only
Controller Functionality Considerations in Dual-IP Mode
Remember the following controller functions when you use Dual-IP mode:
- The controller does not support these functions:
- TCP routing or switching between the two separate networks.
- CIP™bridging of I/O connections (including produce/consume) between the two separate networks
- The controller supports these functions:
- CIP™bridging for non-I/O connections such as HMI, messaging, or sockets between the two separate networks.
- CIP™bridging for UnconnectedCIP™messages between the two separate networks.
