## EtherNet/IP = Ethernet + TCP/UDP/IP + CIP

**IEEE 802.3 Ethernet**

**Network Access**
**Layer**

**ARP**

**IP**

**RARP**

**ICMP**

**OSPF**

**TCP**

**UDP**

**FTP**

**HTTP**

**BOOTP**
**DHCP**

**DNS**

**CIP**

**SNMP**

**Internet**
**Layer**

**Host - to - Host**
**Layer**

**Process**
**Layer**

**IGMP**

**IGRP**

- EtherNet/IP -> Uses the Control and Information                                     Protocol to provide Industrial Services

## Current Plans - Phase II

- If Production Pilot is successful:
- Expand Scope of  EtherNet/IP to Include Robot Communication Level.
- Weld Controllers
- Tag Readers, Vision Inspection Systems
- I/O Definitions Maintained for Multi-Supplier Plug & Play with Architecture
- RS-4
- WS-2
- Define Standard Industrial EtherNet Connector
- Expand Scope of  EtherNet/IP to Include Additional Services.
- Explicit Priority, Change-of-State Behavior
