5.2.6.3.6 RMC EtherNet/IP Definition
5.2.6.3.6.1 RMC EtherNet/IP Object Model
This section describes the EtherNet/IP objects included in the RMC ENET. This information is
useful only to advanced EtherNet/IP users or those who want to use the RMC ENET with an
EtherNet/IP master other than the ControlLogix. For ControlLogix users, the other topics in this
section should be adequate for using the RMC ENET over EtherNet/IP.
The RMC ENET supports the following objects through the following interfaces:
Object Class Instances Interface
Identity 1 Message Router
Message Router 1 Explicit Messaging Connection or
UCMM
Ethernet Link
Object 1 Message Router
TCP/IP Interface
Object 1 Message Router
Connection
Manager 1 Message Router
Assembly Object 3 I/O Connection or Message Router
PCCC Object 1 Message Router
Note: Prior to 20010724 RMC ENET firmware, the Ethernet Link, TCP/IP Interface, and
Assembly objects did not exist. Also, I/O connections were not supported.
The RMC ENET supports a maximum of eight EtherNet/IP connections. As described in RMC
ENET Supported Numbers of TCP and CIP Resources, up to four of these can be I/O
Connections to the Assembly Object, and any remaining can be used for Explicit Message
Connections to the Message Router. In addition, the UCMM can be used to send messages via
the Message Router without using a connection.
The Assembly object has the following three instances:
Instance Data
Type Size Name Description
1 INT 81 Input One sync
register, plus
ten status
words per
axis.
2 INT 2+49 Output Four PLC
status bytes
(internal in the
ControlLogix),
one sync
register, plus
