1. PREFACE

INTRODUCTION

This user manual describes the installation, operation, and diagnostics of the PROFIBUS DP

Slave to EtherNet/IP™ or Modbus Gateway module. The module will hereafter be collectively

referred to as PLX51-PBS.

The PLX51-PBS can operate only as one or more (emulates up to 10) PROFIBUS DPV0/DPV1

Slaves. This allows EtherNet/IP or Modbus devices to exchange process, alarming, and

diagnostic data with other PROFIBUS DP Master(s).

Figure 1.1 –Typical PLX51-PBS PROFIBUS Slave Architecture

Preface

Page 7 of 111

FEATURES

The PLX51-PBS 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-PBS can synchronize to an NTP Server, allowing for automatic time

synchronization. The PLX51-PBS also supports an onboard non-volatile event log for improved

fault finding.

PROFIBUS Slave

The PLX51-PBS can emulate up to 10 PROFIBUS slave devices, providing up to 1536 bytes of

Input and Output Cyclic I/O data between EtherNet/IP or Modbus devices and a PROFIBUS DP

master. Each slave device emulated by the PLX51-PBS 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-PBS 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-PBS also provides

global and device specific statistics.

2. INSTALLATION

MODULE LAYOUT

The PLX51-PBS has one RS485 PROFIBUS DP port as well as two Ethernet ports. 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.

Figure 2.1 –PLX51-PBS Side and Front view

Installation

Page 10 of 111

At the bottom of the module, there is one 3-way power connector.

Figure 2.2 –PLX51-PBS Power connector

The PLX51-PBS 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 PLX51-PBS.

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.

Figure 2.3 –PLX51-PBS Top view

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-PBS 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.
