4 ELC-CAENET
To ensure correct installation and operation of ELC-CAENET, please read this chapter carefully
before using your ELC-CAENET. The ELC-CAENET is an Ethernet remote I/O adapter product
that connects ELC I/O modules to Ethernet networks using either EtherNet/IP or Modbus TCP
protocols. To configure the ELC-CAENET module use EATON’s ELCSoft and ECISoft or an
embedded web page on the device.
The ELC-CAENET supports Modbus TCP server protocol and can be used as remote I/O from
a PLC or other Modbus TCP client devices. The ELC-CAENET can also be used as a Modbus
TCP gateway, supporting the conversion from Modbus TCP commands to Modbus ASCII/RTU.
The ELC-ENET also supports EtherNet/IP adapter functionality to provide remote I/O for a PLC
capable of being an EtherNet/IP scanner.
4.1 Features
zSupports EtherNet/IP Adapter communication with up to 8 connections.
zSupports Modbus TCP server communications with up to 16 connections.
z10/100 Mbps transmission speed; MDI/MDI-X auto-detect.
zSupports up to 16 expansion modules, including up to 8 analog modules
zSupports a maximum of 256 digital Input and Output points.
zIntegrated Modbus TCP to Modbus serial gateway (Allows a Modbus TCP client to
connect to 32 devices on a local modbus serial link).
zSupports embedded “local logic functions”: IF-THEN, counter, timer and real-time clock.
Able to operate independently without control from a main PLC.
zReal time clock synchronized via NTP
zConfigurable using embedded web page or Eaton ELCSoft/ECISoft.

Symbol “R” refers to ready only; “R/W” refers to read and write.
R#0: RTC 0
When the RTC function is enabled, and the assigned trigger RTC condition is true,
ELC-CAENET will set the corresponding bit flag, R0, to ON.
R#1 ~ #15: RTC 1 ~ 15
Same as R#0.
4.6 Modbus TCP Communications
The ELC-CAENET module supports the MODBUS TCP protocol. It acts as a MODBUS TCP
server, providing access to the internal data elements described earlier in this document.

4.7 EtherNet/IP Communications
The ELC-CAENET module supports the EtherNet/IP protocol. It acts as an adapter device. It
provides access to internal data elements through both implicit I/O connections to the I/O
assemblies, and explicit messages to data objects.

failure A connection related service failed along the connection path.
0x 02 Resource
unavailable
Resources needed for the object to perform the requested
service were unavailable.

error
The path segment identifier or the segment syntax was not
understood by the processing node. Path processing shall stop
when a path segment error is encountered.
0x 05

The path is referencing an object class, instance or structure
element that is not known or is not contained in the processing
node. Path processing shall stop when a path destination
unknown error is encountered.

The requested service was not implemented or was not
defined for this Object Class/Instance.
0x 09 Invalid
attribute value Invalid attribute data detected
0x 0E Attribute not
settable A request to modify a non-modifiable attribute was received.
0x 13 Not enough

0x 15 Too much data The service supplied more data than was expected
0x 16 Object does
not exist The object specified does not exist in the device.
0x 20 Invalid
parameter
A parameter associated with the request was invalid. This code
is used when a parameter does not meet the requirements of
this specification and/or the requirements defined in an
Application Object Specification.
0x 26 Path Size
Invalid
The size of the path which was sent with the Service Request
is either not large enough to allow the Request to be routed to
an object or too much routing data was included.
4.8 ELC-CAENET Configuration
Eaton provides software that simplifies the configuration of the ELC-CAENET including the local
logic functions.
This section gives instructions on how to set up ELC-CAENET using this software and
explanation on each setup page. The software uses UDP port 20006 in the set up of the
ELC-CAENET. Appropriate firewall settings will need to be in place for remote access.
ECISoft is a stand alone application that manages the ELC Ethernet components on a network.
This application is integrated into the ELC programming software, ELCSoft.
An embedded web page on the ELC-CAENET also presents the set-up screens described in
