13.4 EtherNet/IP

13.4.1 What is EtherNet/IP?

EtherNet/IP (Ethernet Industrial Protocol) is an industrial multi-vendor real-time Ethernet system
that executes a communication protocol for controlling the Common Industrial Protocol (CIP) in
the application layer implemented over standard Ethernet.
For details on CIP, refer to ODVA documentation.

13.4.2 Cyclic Communication Function

After the scanner device connects to an adapter device and a connection is established, the
cyclic communication function allows them to send data mutually at the requested packet
interval (RPI).
● Scanner device: Controllers such as PLC
● Adapter device: Robot controllers, encoders, I/O devices, etc.
The EtherNet/IP function of the GM1 controller consists of the scanner function and adapter
function.
Supplementary note: About GM1 controllers used as adapter devices
● Adapter devices are classified into the following two types: Adapter devices connected under
the control of the GM1 controller used as a scanner device and adapter devices that are the
GM1 controller itself. To avoid confusion, the following two different terms are used in this
manual.
• Local adapter
Adapter device that is the GM1 controller itself
• Remote adapter
Adapter device connected to the GM1 controller used as a scanner

13.4.3 EtherNet/IP Scanner Function

The EtherNet/IP scanner function allows the GM1 controller to communicate with EtherNet/IP
adapter devices.
Communication settings for an adapter device to be connected can be configured by loading
the EDS file of the adapter device. Multiple adapter devices can be connected to a scanner
device.
