1.1 What is EtherNet/IP?
EtherNet/IP is the industrial network system which is possible to transfer large capacity and wide variety of data
with high speed.
By connecting the limit switches, photo sensors, operating boxes and industrial equipments such as robot
through this network, these equipments are connected with logical access (network I/O). So communication
between the equipments where the hardware connection was hard to be achieved is now improved and diagnosis
of equipments is enabled.
Network speed from 10 Mbps to 100 Mpbps are selectable depending on the network size. (selected
automatically depending on the network)
Two types of communication methods (I/O communication and Explicit communication) are available when
using EtherNet/IP.
・
I/O communication: Communication at high-speed cycle
・
Explicit communication: Communication for settings / monitoring
In this controller, only I/O communications for transferring I/O signals over the network are supported.
The diagram below gives an example of this controller connected to an EtherNet/IP network.
EtherNet/IP is the registered trademark of ODVA (Open DeviceNet Vender Association, Inc.).

With EtherNet/IP, the device called a “master” when using DeviceNet/IP is called a “scanner,” and the device
called a “slave” is called an “adapter.”
