What is EtherNet/IP?
EtherNet/IP is an industrial Ethernet protocol used in Rockwell Automation systems for real-time communication between devices.
Step-by-Step Configuration Guide
Step 1: Assign IP Address
Use BOOTP/DHCP tool or Studio 5000 to assign an IP address to your PLC.
Step 2: Set Subnet and Gateway
Ensure all devices are in the same subnet.
Step 3: Configure in Studio 5000
Add your PLC and modules in the I/O configuration tree.
Step 4: Download Configuration
Download the configuration to the PLC.
Step 5: Test Communication
Use ping and Studio 5000 diagnostics to verify connection.
Common Configuration Mistakes
- IP conflict between devices
- Incorrect subnet mask
- Missing communication modules
