1. PREFACE
INTRODUCTION
This manual describes the installation, operation, and diagnostics of the PLX51-PBM
PROFIBUS DPV0/DPV1 Master/Slave module. The module will hereafter be collectively
referred to as PLX51-PBM.
The PLX51-PBM allows you to interface PROFIBUS DP to EtherNet/IP™.
The PLX51-PBM can operate as a PROFIBUS DPV0/DPV1 Master or multiple PROFIBUS
DPV0/DPV1 Slaves. This allows EtherNet/IP devices (e.g. Rockwell Logix platform) to exchange
process, alarming, and diagnostic data with PROFIBUS DP devices, as well as provide
parameterization and asset management of slave devices using Device Type Managers
(DTMs).
The PLX51-PBM slave feature can operate only as one or more PROFIBUS DPV0/DPV1 Slaves.
This allows EtherNet/IP devices to exchange process, alarming, and diagnostic data with other
PROFIBUS DP Master(s).

Preface
FEATURES
The PLX51-PBM can be set to operate as either a PROFIBUS DP Master or Slave.
The PLX51-PBM has two Ethernet ports allowing for either a Linear or Ring (Device Level Ring
– DLR) Ethernet topology. The Ethernet ports can also be set up for port mirroring allowing
for better fault analysis.
The PLX51-PBM can synchronize to an NTP Server, allowing for automatic time
synchronization. The PLX51-PBM also supports an onboard non-volatile event log for
improved fault finding.
PLX51-PBM as a PROFIBUS Master
The PLX51-PBM can exchange process data (DPV0) with up to 125 PROFIBUS DP slave devices,
providing up to 1536 cyclic bytes input and 1536 bytes output data. The data is formatted into
the engineering units for use in a Logix platform by using the automatically generated
mapping imports for Logix User Defined Data Types (UDTs).
The PLX51-PBM also provides DPV1 communication allowing you to exchange DPV1 Class 1
and Class 2 data with each slave device. The PLX51-PBM Gateway DTM can be used to
configure and parameterize each slave device using Device Type Manager (DTM) technology.
From a Logix controller, the PLX51-PBM allows you to monitor and extract DPV1 alarms from
each slave device on the connected PROFIBUS DP fieldbus.
PLX51-PBM as a PROFIBUS Slave
The PLX51-PBM can also be configured to emulate up to 10 PROFIBUS slave devices, providing
up to 1536 bytes of Input and Output Cyclic I/O data between EtherNet/IP devices and a
PROFIBUS DP master. Each slave device emulated by the PLX51-PBM can be configured to
provide DPV0 data exchange with a PROFIBUS Master on the network.
The data is formatted into the engineering units for use in a Logix platform by using the
automatically generated mapping imports for Logix User Defined Data Types (UDTs).
Each emulated slave can also be configured to exchange DPV1 Class 1 data by mapping Logix
tags for the relevant DPV1 data exchange. Each emulated slave is able to provide DPV1
alarming for the PROFIBUS Master.
The PLX51-PBM provides a range of statistics and tools to provide a detailed diagnostic
overview of each emulated slave which speeds up fault finding. The PLX50 Configuration
Utility allows you to perform a PROFIBUS DP packet capture of the running Fieldbus which
can be used to analyze the bus behaviour and packets received. The PLX51-PBM also provides
global and device specific statistics.

2. INSTALLATION
MODULE LAYOUT
The PLX51-PBM has one RS485 PROFIBUS DP port as well as two Ethernet. The Ethernet cable
must be wired according to industry standards, which can be found in the Additional
Information section of this document.
The module provides six diagnostic LEDs, as shown in the front view figure below. These LEDs
are used to provide information regarding the module system operation, the Ethernet
interface, and the PROFIBUS network status.

Installation
DIP Switch
Description
DIP 1
Used to force the module into “Safe Mode”. When in “Safe Mode”, the module will
not load the application firmware and will wait for new firmware to be downloaded.
This should only be used in the rare occasion when a firmware update was interrupted
at a critical stage.
DIP 2
This forces the module into DHCP mode which is useful when you have forgotten the
IP address of the module.
DIP 3
This is used to lock the configuration from being overwritten by the PLX50
Configuration Utility. When set, the PLX50 Configuration Utility will not be able to
download to the PLX51-PBM module.
DIP 4
When this is set, a module reboot will set the module Ethernet IP address to
192.168.1.100 and network mask 255.255.255.0. You can then switch the DIP switch
off and assign the module a static IP address if needed.
At the bottom of the PLX51-PBM module, there is one 3-way power connector.
Figure 2.2 – PLX51-PBM Power connector
The PLX51-PBM has an input voltage range of 10 to 36 VDC, applied to the module via the
power connector. The power connector also provides an Earth connection for the PLX51PBM.
NOTE: It is recommended to always have a good clean earth connected to the
module via the Earth connector on the power connector.
At the back of the module, there is slot for a SD memory card. The module provides four DIP
switches at the top of the enclosure as shown in the top view figure below.

Installation
MODULE MOUNTING
The PLX51-PBM provides a DIN rail clip to mount onto a 35mm DIN rail.
Figure 2.4 - DIN rail specification
The DIN rail clip is mounted at the back of the module as shown in the figure below. Use a flat
screw driver to pull the clip downward. Once the module is mounted onto the DIN rail, the
clip must be pushed upwards to lock the module onto the DIN rail.

3. SETUP
INSTALLING THE CONFIGURATION SOFTWARE
All PLX51-PBM network setup and configuration is done in the ProSoft PLX50 Configuration
Utility. This software can be downloaded from: www.prosoft-technology.com
Figure 3.1. - ProSoft PLX50 Configuration Utility Environment
Page 17 of 162
Setup
NETWORK PARAMETERS
The PLX51-PBM has DHCP (Dynamic Host Configuration Protocol) enabled as factory default.
Thus, a DHCP server must be used to provide the module with the required network
parameters (IP address, subnet mask, etc.). There are a number of DHCP utilities available,
however it is recommended that the DHCP server in the PLX50 Configuration Utility is used.
Within the PLX50 Configuration Utility environment, the DHCP server can be found under the
Tools menu.
Figure 3.2. - Selecting DHCP Server
Once opened, the DHCP server listens on all available network adapters for DHCP requests
and display their corresponding MAC addresses.
Figure 3.3. - DHCP Server
NOTE: If the DHCP requests are not displayed in the DHCP Server, it may be
due to the local PC’s firewall. During installation, the necessary firewall rules
are automatically created for the Windows firewall. Another possibility is that
another DHCP Server is operational on the network and it has assigned the IP
address.
Page 18 of 162
Setup
To assign an IP address, click on the corresponding ASSIGN button. The Assign IP Address for
MAC window opens.
Figure 3.4. - Assigning IP Address for MAC
The required IP address can be either entered, or a recently used IP address can be selected
by clicking on an item in the Recent list.
If the Enable Static checkbox is checked, the IP address will be set to static after the IP
assignment, thereby disabling future DHCP requests.
Once you click OK, the DHCP server will automatically assign the IP address to the module and
then read the Identity object product name from the device.
The successful assignment of the IP address by the device is indicated by the green
background of the associated row.
Figure 3.5. - Successful IP address assignment
It is possible to force the PLX51-PBM back into DHCP mode by powering up the device with
DIP switch 2 set to the On position.
Page 19 of 162
Setup
A new IP address can then be assigned by repeating the previous steps.
NOTE: It is important to return DIP switch 2 back to Off position, to avoid the
module returning to a DHCP mode after the power is cycled again.
In addition to the setting the IP address, a number of other network parameters can be set
during the DHCP process. These settings can be viewed and edited in the PLX50 Configuration
Utility Application Settings, in the DHCP Server tab.
Once the DHCP process is complete, the network settings can be set using the Ethernet Port
Configuration via the Target Browser.
The Target Browser can be accessed under the Tools menu.
Figure 3.6. - Selecting the Target Browser
The Target Browser automatically scans the Ethernet network for EtherNet/IP devices.
Figure 3.7. - Target Browser
Page 20 of 162
Setup
Right-clicking on a device, reveals the context menu, including the Port Configuration option.
Figure 3.8. - Selecting Port Configuration
The Ethernet port configuration parameters can be modified using the Ethernet Port
Configuration window.
Figure 3.9. - Port Configuration
Alternatively, these parameters can be modified using Rockwell Automation’s RSLinx
software.

Setup
GSD FILE MANAGEMENT
Each PROFIBUS device has a GSD file that is required to provide information needed to
configure the device for data exchange. The PLX50 Configuration Utility manages the GSD
library which is used for adding devices to the PLX51-PBM.
1 The GSD File Management Tool is opened by selecting GSD File Management under
the Tool menu in the configuration utility.
Figure 3.10 – Launching the GSD File Management Tool
2 Once the tool opens, a list of registered slave devices are displayed, using their GSD
files.

Page 22 of 162
Setup
3 To add a GSD file, select the Add option under the GSD File menu.
Figure 3.12 – GSD File Adding
4 Select the required GSD file and click OPEN.
Figure 3.13 – Adding GSD File
5 Once the file has been selected, the GSD File Management tool adds the slave device
to the device list and recompile the GSD catalog.
Page 23 of 162
Setup
A GSD catalog can be exported from another PLX50 Configuration Utility by exporting the GSD
catalog from one PLX50 Configuration Utility, and importing it in another. This is done by
selecting either Import or Export under the Catalog menu as shown below:
