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 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.
