Prosoft PLX51-PBM PROFIBUS DP Master/Slave to EtherNet/IP™, Modbus TCP/IP®, or Modbus® Serial Gateway

The PLX51-PBM gateway provides connectivity to EtherNet/IP™, Modbus TCP/IP®,

or Modbus® Serial networks for PROFIBUS DP networks by operating as either a

Master or Slave device on the PROFIBUS DP network.

For easy integration to a Rockwell Automation Controller, the gateway and

configuration software create dynamic AOI’s based on the user configuration to add

logical tag names to the PLC project file. Thus, reducing the overall programming

time for EtherNet/IP applications.

For configuration of Modbus TCP/IP or Modbus Serial Networks, the module will

automatically map PROFIBUS DP data points to registers on a Modbus network.

With advanced tools such as PROFIBUS device discovery and a built-in PROFIBUS

DP packet capture utility, PROFIBUS DP network commissioning time can be greatly

reduced.

Dual Ethernet ports of the module can support either DLR (Device Level Ring)

topology, or can be used as an embedded switch for flexible installation options.

With support for up to 1536 bytes of Input and Output data, and up to 4 EtherNet/IP

connections to the processor, this module provides performance and data throughput

back to the processor for even the most demanding of PROFIBUS applications.

When used as a PROFIBUS DP slave, the module can operate as 1 to 10 slaves,

providing up to 1536 bytes of Input and Output Cyclic I/O data between EtherNet/IP,

Modbus TCP/IP, or Modbus Serial devices and a PROFIBUS DP master.

Features

 Supports DLR for EtherNet/IP networks

 Support for either EtherNet/IP, Modbus TCP/IP, or Modbus Serial Communication networks

 PROFIBUS master or slave (with multi-slave support)

 Built-in PROFIBUS packet capture tool

Configuration

The PLX50 Configuration Utility software is used for configuration and troubleshooting of 

the module. The stand-alone configuration utility allows users to define the setup and

configuration of the PROFIBUS DP network, connections with Rockwell Automation

controllers and devices over EtherNet/IP, and build custom Add-On Instructions (AOIs)

to be imported into Studio 5000 applications.

With the ability to import custom AOI’s into the Studio 5000 environment and advanced

PROFIBUS DP tools such as the packet capture utility, commissioning time of a network

can be greatly reduced.

EtherNet/IP Server (Class 1 Adapter)

As an EtherNet/IP server, the gateway operates as an Adapter with up to 4 Class 1 I/O

connections to a Controller (Scanner) on an EtherNet/IP network. The use of

EtherNet/IP Class 1 I/O connections for transfer of PROFIBUS DP cyclic data, provides

fast data transfer between networks for increased performance on time critical

PROFIBUS DP applications.

Modbus TCP/IP

On a Modbus TCP/IP network, the module will operate as either a Modbus TCP/IP

Client or Server device.

As a Modbus TCP/IP client the module can be configured to automatically read/write all

PROFIBUS DP data with a slave device for easy setup and configuration, or the

Modbus Auxiliary Map feature will allow you to configure data transfer to customize the

mapping to meet specific application requirements.

As a Modbus TCP/IP Server all information from the PROFIBUS DP network is stored in

continuous registers in the module for easy configuration and efficient mapping of data

to a Modbus TCP/IP client.

Modbus Serial

On a Modbus Serial network the module will operate as either a Master or a Slave

device supporting either RS232 or RS485 communication networks.

As a Modbus Serial Master the module can be configured to automatically read/write all

PROFIBUS DP data with a slave device for easy setup and configuration, or the

Modbus Auxiliary Map feature will allow you to configure data transfer to customize the

mapping to meet specific application requirements.

As a Modbus Serial Slave all information from the PROFIBUS DP network is stored in

continuous registers in the module for easy configuration and efficient mapping of data

to an attached master device.

PROFIBUS DP Master V1

Cyclic or acyclic data can be transferred with Class 1 or Class 2 DPV1 services,

allowing communication with slave devices supporting PROFIBUS DPV0 or V1

protocols. The gateway acts as an input/output link between the PROFIBUS network

and the EtherNet/IP protocol. Data transfer by the EtherNet/IP protocol is asynchronous

from data transfer on the PROFIBUS network.
