Introduction of Features
EtherNet/IP
EtherNet/IP is a protocol that extends
Common Industrial Protocol (CIP) to Ethernet.
The use of Ethernet enables high-speed and periodic exchange of massive control and
monitoring data between control devices placed at dispersed locations.
Devices that support EtherNet/IP are available from many vendors. Among them,
Rockwell Automation's Programmable Logic Controller (PLC) and Remote I/O of the
Allen-Bradley brand are widely used. Yokogawa's DX, equipped with the EtherNet/IP
server function, supports communications with these PLCs.
Configuration Components
• Scanner (
Client)
A device that launches a request on EtherNet/IP. This is either a PLC or PC. For the
DX, PLCs such as Allen-Bradley PLC-2, PLC-5, SLC 500, MicroLogix, CompactLogix,
and ControlLogix represent a Scanner (Client).
•
Adapter (Server)
A remote I/O device that the Scanner (Client) can access to read or write data. The
DX is an Adapter (Server).
•
Configuration tool
A tool used to configure the system. This is either a PC on which configuration
software has been installed or the software itself.
Rockwell Automation RSLogix500 and RSLogix5000 and the communication driver
software RSLinx are configuration tools.
