1.2.1
PROFIBUS Master
The PLX51-PBM can exchange process data (DPV0) with up to 125 PROFIBUS DP
slave devices. The data is formatted into the engineering units for use in either a
Logix platform or Modbus device by using the automatically generated mapping
imports for Logix User Defined Data Types (UDTs) or padding for Modbus Registers.
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.
The PLX51-PBM will allow the user to monitor and extract DPV1 alarms from each
slave device on the connected PROFIBUS DP fieldbus from either a Logix controller
or Modbus Master device.
1.2.2
PROFIBUS Slave
The PLX51-PBM can also be configured to emulate up to 10 PROFIBUS slave
devices. Each slave device emulated by the PLX51-PBM can be configured to
provide DPV0 data exchange with a PROFIBUS Master on the network.
The data will be formatted into the engineering units for use in either a Logix platform
or Modbus device by using the automatically generated mapping imports for Logix
User Defined Data Types (UDTs) or padding for Modbus Registers. The latter
ensures alignment with the 16-bit data structure.
Each emulated slave can also be configured to exchange DPV1 Class 1 data by
mapping either Logix tags or Modbus registers for the relevant DPV1 data exchange.
Each emulated slave will also be able to provide DPV1 alarming for the PROFIBUS
Master.
The PLX51-PBM provides a range of statistics and tools to provide a detailed
diagnostic overview of each PLX51-PBM which speeds-up fault finding. The
Configuration Utility allows the user to perform a PROFIBUS DP packet capture of
the running fieldbus which can be used to analyse the bus behaviour and packets
received. The PLX51-PBM also provides global and device specific statistics.
