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.
13.4.4 Setting up the EtherNet/IP Scanner Function
