EtherNet/IP Modes
Two
EtherNet/IP™
modes are available on the controller.
- Dual-IP (Default)
- Linear/DLR
The controller can connect to these
EtherNet/IP™
network levels: - Enterprise-level Network
- Device-level Network
The advantage of connecting to separate network levels is that you can segment the networks and isolate the communication on each. For example, communication that is required for the controller to execute a task is restricted to the device-level network.
Network segmentation and the resulting communication isolation can help provided enhanced security in your application. Additionally, the option to connect to separate network levels helps you organize the networks in your application in a more logical manner.
Enterprise-level Network
Port 1 can only be connected to an enterprise-level network.
IMPORTANT:
When you set the IP address and subnet mask, you establish an IP address range for the port. Make sure that the IP address ranges that are established for each port on the controller do not overlap. For more information on overlapping IP address ranges, see Overlapping IP Address Ranges.
When you connect port 1 to an enterprise-level network, you configure the following parameters:
- IP address (required)
- Subnet mask, also called the network mask (required)
- Gateway address (optional)
- Host name (optional)
- Domain name (optional)
- Primary DNS server address (required if your controller makes DNS requests.)
- Secondary DNS server address (required if your controller makes DNS requests.)
Device-level Network
Remember the following when you connect to device-level networks:
- You are not required to connect the controller to an enterprise-level network to connect to device-level networks.
- You can connect port 1, port 2, or ports 1 and 2 to device-level networks.
When you connect a port to a device-level network, you configure the following parameters:
- IP address (Required)
- Subnet mask, also called the network mask (Required)
- Gateway address (Optional)
- Host name (Optional)
