1. Introduction to EtherNet/IP
EtherNet/IP is
a communication protocol used in industrial automation, and can be applied for
control, security, synchronization, motion control, configuration and information. This industrial
Ethernet communication protocol is managed by the ODVA Association (Open DeviceNet Vendors
Association). The name "IP" stands for "Industrial Protocol". EtherNet/IP is based on TCP/IP
communication protocol so it can easily work with generally-used IT networks and provides high-
speed and stable applications for Factory Automation (FA), Building Automation (BA), and Program
Automation (PA). Delta's EtherNet/IP products cover a wide range of control and drive products,
such as Programmable Logic Controllers (PLC), Variable Frequency Drive (VFD), Human-Machine
Interface (HMI), thermostats (DTM), switches (Ethernet Switch), and so on. It can also be connected
with other brand EtherNet/IP devices through EDS files. For correct communication, use Delta's
products as your first choice for PLC.
Option cards that support EtherNet/IP for M300 and C2000 drive series are CMM-EIP02/03 and
CMC-EIP01/02. You can also use DCISoft software to remotely set and monitor through the Internet,
or remotely monitor by using CMM-EIP02 that works with drawing control software or HMIs. If you
use devices that support auto MDI / MDI-X detection function, you do not need to use crossover
cables.
