Note For an EtherNet/IP Unit or built-in EtherNet/IP port with version 2.0 or higher,
The CS/CJ-series EtherNet/IP Units and built-in EtherNet/IP ports are
equipped with a PLC Object that is functionally compatible with CS/CJ-series
DeviceNet Units. The Unit will receive messages addressed to the PLC
Object, process service requests addressed to the CPU Unit, and return
responses. The CS/CJ-series EtherNet/IP Units and built-in EtherNet/IP ports
support CIP unconnected message (UCMM) communications and CIP con-
nected (Class 3) communications as reception functions.
The following services are provided by the PLC Object.
Explicit messages can be received from the following sources:
change the class ID of the PLC Object from 2F hex to C4 hex.
When using a PLC Object with a DeviceNet Unit or EtherNet/IP Unit with ver-
sion 1.0, and converting to EtherNet/IP Unit or built-in EtherNet/IP port with a
version 2.0 or higher, the class ID must be changed according to the commu-
nications application.
• CPU Unit status read/write
• CPU Unit I/O memory read/write
• CPU Unit error log read/clear
• EtherNet/IP nodes made by other manufacturers
• OMRON PLCs with a CS/CJ-series EtherNet/IP Unit or a CPU Unit with a
built-in EtherNet/IP port. (Messages from CS/CJ-series EtherNet/IP Units
and built-in EtherNet/IP ports must be CIP unconnected messages
(UCMM).)*
* Messages from CS/CJ-series EtherNet/IP Units and built-in EtherNet/IP
ports must be CIP unconnected messages (UCMM).
