Page 6: Preface
This manual describes the installation, operation, and diagnostics of the ProSoft PLX51-PBM PROFIBUS DPV0/DPV1 Master/Slave module. The PLX51-PBM allows the user to interface PROFIBUS DP to EtherNet/IP or Modbus (RTU232, RTU485, TCP/IP). The PLX51-PBM can either operate as a PROFIBUS DPV0/DPV1 Master or multiple PROFIBUS DPV0/DPV1 Slaves.
Page 7: Features
The PLX51-PBM will allow the user to interface PROFIBUS DPV0/DPV1 to either EtherNet/IP or Modbus. The PLX51-PBM can be set to operate as either a PROFIBUS DP Master or Slave. The PLX51-PBM, when configured as a Master can exchange up to 2 kilobytes of PROFIBUS device and status data (72 bytes are reserved for master status, and 8 bytes for each configured slave).
Page 8: Profibus Master
The latter ensures alignment with the 16-bit data structure. The PLX51-PBM also provides DPV1 communication allowing the user 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.

Page 12: Installation
Installation Module Layout The PLX51-PBM has one RS485 PROFIBUS DP port as well as two Ethernet ports at the front of the module. The Ethernet cable must be wired according to industry standards which can be found in the additional information section of this document.
Page 13 PROFIBUS DPV0/DPV1 Master or Slave to EtherNet/IP™ or Modbus® Gateway User Manual The PLX51-PBM has an input voltage range of 10-36Vdc that needs to be applied to the module via the power connector. The power connector also provides an Earth connection for the PLX51-PBM.
Page 14 This DIP Switch 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 DIP Switch is set at bootup it will force the module Ethernet IP address to 192.168.1.100 and network mask 255.255.255.0.
