1.2 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).
The PLX51-PBM has two Ethernet ports allowing the user to have either a Linear or
Ring (Device Level Ring – DLR) Ethernet topology. The Ethernet ports can also be
setup 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.
