3.3.10 EtherNet/IP Function (/E1 option)

EtherNet/IP Overview
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 GM, equipped with the EtherNet/IP server function, supports
communications with these PLCs.

GM Functions
The GM provides the following functions:
• Participate in an EtherNet/IP network as an Adapter (Server).
• Communicate with new and old Allen-Bradley PLCs such as MicroLogix, CompactLogix,
ControlLogix, SLC 500, PLC-5, and PLC-2.
• Support both Explicit and I/O messages.
Explicit Message Target PLC Command name
Explicit Message PLC-2 PLC2 Unprotected Read/Write
PLC-5 PLC5 Word Range Read/Write
PLC5 Typed Read/Write
SLC SLC Typed Read/Write
• PLCs can access internal data of the GM.
