EtherNet/IP Device
Introduction
This section describes the configuration of the EtherNet/IP Device (CIP) to the controller.
For further information about EtherNet/IP (CIP), refer to the www.odva.org website.
Adding an EtherNet/IP Device
See Adding an EtherNet Manager
EtherNet/IP Device Configuration
To configure the EtherNet/IP device parameters, double-click Ethernet → EthernetIP in the
Devices tree.
The following dialog box is displayed:
186
The EtherNet/IP configuration parameters are defined as:
Instance:
Number referencing the input or output Assembly.
Size:
Number of channels of an input or output Assembly.
The memory size of each channel is 2 bytes that stores the value of an %IWx or %QWx object, where x is the channel number.
EIO0000004135 09/2020
Ethernet Configuration
For example, if the Size of the Output Assembly is 20, it represents that there are 20 input channels (IW0...IW19) addressing %IWy...%IW(y+20-1), where y is the first available channel for the Assembly.

EDS File Generation
You can generate an EDS file to facilitate configuring EtherNet/IP cyclic data exchanges.
To generate the EDS file:
Step
1
2
3
Action
In the Devices tree, right-click the EthernetIP node and choose the Export as EDS command from the context menu.
Modify the default file name and location as required.
Click Save.
NOTE: The Major Revision and Minor Revision objects in the EDS file are used to ensure uniqueness of the EDS file. The values of these objects do not reflect the actual controller revision level.
The EDS file is generated automatically in the "/usr/Eip" directory within the controller when an application is downloaded, or at start-up when a boot application exists, according to the parameters above.
NOTE: The EDS file is generated when the control network is working correctly on the controller
(cable connected and the IP address is acquired).

Output means OUTPUT from Originator controller (= %IW for the controller).
Input means INPUT from Originator controller (= %QW for the controller).
Connections on EtherNet/IP
To access a target device, open a connection (global name used by EtherNet/IP protocol level) which can include several sessions that send requests.
One explicit connection uses one session (a session is a TCP or UDP connection.
One I/O connection uses 2 sessions.
The following table shows the EtherNet/IP connections limitations:

NOTE: The Assembly object binds together the attributes of multiple objects so that information to or from each object can be communicated over a single connection. Assembly objects are static.
The Assemblies in use can be modified through the parameter access of the network configuration tool (RSNetWorx). The controller needs to recycle power to register a new Assembly assignment.

Instance Code
The File object provides download functionality for the EDS and EDS Icon files. The following instances of the File object are implemented:
Instance C8 hex returns an uncompressed version of the EDS text file. The instance name attribute is returned as "EDS and Icon Files". The file name attribute returns "M258xxx.eds"
where M258xxx is the exact reference of the controller. The contents of the EDS file are adjusted dynamically by the controller. The connection data sizes in the EDS file are adjusted to reflect the actual standard Assembly instance sizes.
Instance C9 hex returns a compressed version of the device EDS icon file. The instance name is returned as "Related EDS and Icon Files". The file name attribute returns "M258xxx.gz" where
M258xxx is the exact reference of the controller. This is zip encoded file containing only one file:
M258xxx.ico. The file is encoded with the ZLIB compression file format. ZLIB is a free, general purpose, legally unencumbered, loss-less compression library. The specifications are available from the Internet Engineering Task Force (http://www.ietf.org).

NOTE: The Read Register service requires 4 bytes of data: the first word contains the starting register address and the second word contains the number of registers to read. The Write service request requires the same 4 bytes, followed by the actual data.
The Modbus Pass-through service indicates a specific Modbus function. The translation function will not perform any Indian conversion on the request or response data. Both request and response contain 1 byte of the Modbus Function code followed by the Modbus message data, including a sub-function code if present.
