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

Description

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.

Architectures

Features and Benefits

• 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.

Specifications

EtherNet/IP™ Server

As an EtherNet/IP server, the gateway can support up to 4 Class 1 I/O connections back to a Controller on an EtherNet/IP network. Additionally, the server can respond to Class 3 messages from an EtherNet/IP client for the transfer of Status and PROFIBUS DP data.

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.
