1 X20BC0088 Overview
TM
The EtherNet/IP bus controller (X20BC0088) allow connecting X20-, X67-, and XV-I/O modules to an AllenTM
Bradley® Master (Scanner) with the EtherNet/IP protocol. B&R IO can be configured with default module
TM
functionality directly with RSLogix 5000, or configured using FieldbusDESIGNER. This tool features a comprehensive help system for first time users, and offers a very familiar interface for experienced B&R users.
With FieldbusDESIGNER, users can configure modules, get details on I/O mapping, and even create complete project files giving easy access to user defined I/O data points instead of byte arrays. FieldbusDESIGNER can be downloaded for free (www.br-automation.com).
TM
TM
The EtherNet/IP bus controller was created in compliance with the EtherNet/IP specification governed by
ODVA (Open DeviceNet Vendor Association). When using FieldbusDESIGNER, the default CPU for the generated project is the 1769-L35E CompactLogix® Controller. However, the generated project can be used for
any Logix platform.
This document will provide the programmer with a detailed description of the bus controller including how to
setup, configure and diagnose the module. Further information about this module can be obtained from the
document list in Section 8: Appendix.

The last position of the IP address saved in flash memory is temporarily replaced with the station number. The IP address stored in the flash memory is
not changed.
0x80 - 0xEF
IP is temporarily set by DHCP server.
DHCP host name is: “br” + MAC address
Example of a default host name:
MAC address: 00-60-65-00-49-02
Resulting host name: br006065004902
The IP address stored in the flash memory is not changed.
0xF0 - 0xFE
0xFF
Reserved. Currently same as 0xFF.
Boots with default values:
IP address: 192.168.100.1
Network mask: 255.255.255.0
Gateway: 192.169.100.254
The IP address stored in the flash memory is not changed.
The bus controller can be addressed via Windows® NetBIOS service (only if no other routers or gateways are in
the way):
Primary NetBIOS name is identical to DHCP host name (“br” + MAC address)
Secondary NetBIOS name is: “br” + “eip” + station number (three decimal places)
This means that the following secondary NetBIOS name is generated for a station number: e. g. 0xD7 (dec. 215): "breip215"
For station number 0x00 the secondary NetBIOS name is identical to DHCP host name.

1.2 Supported 3rd Party Hardware and Software
TM
TM
The X20BC0088 module adheres to the EtherNet/IP specification, so it can operate with any EtherNet/IP
TM
scanner. All documentation, examples, and FieldbusDESIGNER support is for the RSLogix 5000 software
using a CompactLogix® CPU.
1.2.1 Supported Allen-Bradley® CPUs
Allen-Bradley® CPUs from the Logix family including CompactLogix® and ControlLogix®, FlexLogix®, and
DriveLogix®. The default processor for FieldbusDESIGNER is the CompactLogix® 1769-L35E.
1.2.2 Supported Allen-Bradley® Software
All functional testing was performed using RSLogixTM 5000 versions 15.01 and 16.03
1.3 Overview of Programming Options
There are two options for programming the X20BC0088: Default Setup and FieldbusDESIGNER setup.
TM
Default setup allows the programmer to stay within the RSLogix 5000 programming environment, and does
not require additional software (refer to Section 2: Default Setup). Each module connected behind the bus
controller is used in its default configuration and I/O points are manipulated through their respective byte offsets. If configuration of modules beyond their default configuration is needed, it must be done with explicit
messages in RSLogixTM 5000, or by directly connecting to the module (e.g. Telnet).
FieldbusDESIGNER setup allows the programmer more configuration options. Modules can be configured
beyond their default setups and I/O points can be assigned a descriptive name. FieldbusDESIGNER generates an *.L5K file which can be directly imported with RSLogix® 5000.
7
User's Manual
2 Default Setup
TM
Default setup is done completely within RSLogix 5000 using each X20 and X67 module’s internally stored
default setup. If necessary, this default setup can be altered later using explicit messages or by directly connecting to the bus controller. This setup mode is recommended for systems which have a limited number of
Digital and Analog I/O points, or systems that allow for modules to operate in their default configuration. Additional modules can be added to a system at any time, with no (or very limited) changes to the system required.
The following programs are required:
TM
RSLogix 5000 V15 or V16 (programming)
TM
RSLinx (online communication)

3 FieldbusDESIGNER Setup
FieldbusDESIGNER is used to configure B&R fieldbus components and provides a programming environment very similar to B&R Automation Studio. Modules can be setup beyond their default configuration, and
unique names can be assigned to each module’s I/O points. When configuration is complete, a build is perTM
formed which generates an *.L5K file. This file can be imported into RSLogix 5000.
FieldbusDESIGNER is available on the B&R website under section ‘Service Material Related Downloads
Automation Software Automation Studio FieldbusDESIGNER’:

2) Click the “ETHERNET-MODULE ST1 from FieldbusDESIGNER project, drag and drop it into the new
project
This will copy the BC0088 module and its assemblies into the new project.
26
User's Manual
3) If the IO channel names want to be preserved, the User-defined data types must be transferred next. The
data types can be transferred the same as the module: by drag and drop between open instances. If acTM
cess directly to the IO assembly please reference Section 2.1.3 Online with RSLogix 5000.
4) Within the Controller tags, define tags for the Input and Output Assemblies. Controller tags, can be defined, or they can be dragged and dropped between instances. Also, transfer the lifecycle counters (copyInpCounter, copyOutCounter, and mainCounter).
5) Transfer the programs between the projects. Programs can be dragged and dropped like the bus controller and data types.
27
User's Manual
6) Ensure the order stays the same: Copy Inputs, Execute main program, and Copy Outputs.
7) Ensure the IO structures are tied correctly to the copy function blocks.
The project is now transferred.

4 Bus Controller Capabilities
4.1.1 Speed and Performance
X2X cycle times as low as 0.5ms can be achieved, as well as RPI as low as 1.0ms. The number of modules
behind a bus controller is limited by the X2X cycle time and the size of the configuration assembly. The configuration size can be minimized by grouping similar modules under one bus controller.
4.1.2 System Size Limits
The total number of modules behind a bus controller is dependent on the configuration buffer limit of the master and the X2X cycle time. The master is allowed 400 Bytes of configuration data in the configuration buffer.
The amount of configuration data required for a module is dependent on the number of configuration registers
used per module. If a wide variety of modules are used, the number of modules will be severely limited. If
many of the same module type are used, compression of the configuration data allows for more modules.
If FieldbusDESIGNER is used to build a system, the size of the configuration, Output, and Input assemblies is
given upon successful project build.
If more modules are required, they can be split between multiple bus controllers. The bus controller network
can have up to a few hundred analog and a few hundred digital I/O modules (253 modules in total).
Limits (Set by Allen-Bradley®):
Configuration data: 400 Bytes
Output Assembly: 496 Bytes
Input Assembly:
500 Bytes
Each Byte represents 8 digital I/O on a X20DI9371 or an X20DO9322 module.

4.1.3 Guidelines for Proper Operation
The following items work without limitations:
•
•
•
•
Standard I/O Modules (X20, X67, XV)
All standard DC modules (X20)
Node number modules (X20/X67)
Switching function models
The following items work with limitations:
•
•
Serial interfaces (X20CS10x0) can only be used behind a bus controller when operated in default
‘bus controller’ function model called “flat stream” mode
Stepper modules (X20SMxxxx) have to be operated in “ramp” function model
Not supported at this time:
•
•
B&R NetTime and module functions that use it
Special module functions requiring data exchange between module and application w/o handshaking
(stream X2X communication) like transmitting scope data with an X20AIx632 – see module documenation for more details
4.2 Optimized Performance
4.2.1 Setting Proper RPI and X2X Time
The RPI (Request Packet Interval) controls the update rate for the BC0088 module’s connection. This value
TM
can be changed within RSLogix 5000 by right clicking on the Generic Ethernet Module and selecting
“Properties.” The minimum value for RPI is 1 ms, and the default is 10 ms.
30
User's Manual
The X2X cycle time can be adjusted in FieldbusDESIGNER under ‘Adapter Configuration’ or through accessing
attribute ID 0x80 of the ‘bus controller’ object (class 0x64, instance 0x1). The default value is 1ms. After making
changes, the bus controller must be restarted for the changes to take effect.

5 Module Configuration / Writing to Registers
Modules can be configured by writing to their registers. This allows for dynamic configuration of modules
TM
within RSLogix 5000 by using explicit messages.
Service Code = 0x33 for write command
Class = 0x65 for I/O modules
Instance = 2 = Module location on rack (See figure below)
Attribute = 0 = can be left to 0 for this type of service
Source Length = 6 = length of address and data in bytes: address is 2 bytes, data is always 4 bytes
Source Element = array of 6 SINT: address is write_data[0…1], data is write_data[2..5]
Register addresses and configuration data can be taken from the “MAX20REGISTER-ENG” and
“MAX67ENG” document.
33
User's Manual
The MSG function block’s configuration is shown below.
Configuration registers can be read by calling service 0x32 of the same object:
Source Length = 2 = length of register address in bytes
Source Element = array of 2 SINT: address is write_data[0…1]
The service will return a 4 byte value (the register’s data).
