Explicit Message Communications
Explicit messages defined in EtherNet/IP can be used to send service
requests to other companies’ EtherNet/IP masters/slaves and OMRON PLCs
with CS/CJ-series EtherNet/IP Units and built-in EtherNet/IP ports.
Note Specific FINS commands (commands 2810 and 2801) are used to send
explicit messages.
Note The CS/CJ-series EtherNet/IP Units and built-in EtherNet/IP ports (CS1W-
EIP21, CJ1W-EIP21, CJ2H-CPU
@@
-EIP, or CJ2M-CPU3
@
) contain a PLC
Object, so that other devices can read/write the I/O memory of the CPU Unit
with the built-in EtherNet/IP port or the CPU Unit to which the EtherNet/IP Unit
is mounted.

CIP UCMM messages can be sent to an EtherNet/IP
Unit or built-in EtherNet/IP port by a CMND(490)
instruction containing FINS command code 2810
Hex.
Automatically responds to explicit mes-
sages from other devices.
Functions supported
in remote devices
• Masters/slaves made by other manufacturers:
Supported services determine supported functions.
• PLC with a CS/CJ-series EtherNet/IP Unit or built-in
EtherNet/IP port:
Supports the reading/writing of a remote CPU Unit’s
status information and I/O memory data.
• Masters made by other manufacturers
• PLC with a CS/CJ-series EtherNet/IP Unit
or built-in EtherNet/IP port: Supports the
reading/writing of the local CPU Unit’s sta-
tus information and I/O memory data.
