Overview
The PA Link module simplifies the implementation of PROFIBUS PA by combining an EtherNet/IP and ModbusTCP Linking device with an internal isolated power conditioner and bus terminator.
The PA Link can either operate as a PROFIBUS DPV0/DPV1 master allowing EtherNet/IPThe PA Link can either operate as a PROFIBUS DPV0/DPV1 master allowing EtherNet/IP devices (e.g. Rockwell Logix platforms) or Modbus devices to exchange process, alarming, and diagnostic data with PROFIBUS PA devices as well as provide parameterization and asset management of slave devices using Device Type Managers (DTMs).
The module supports up to 32 PA slave devices and is capable of exchanging up to 2 kilobytes of PROFIBUS data with either a Rockwell Automation Logix controller or any Modbus TCP master or slave device.
The internal power conditioner is capable of supplying up to 420 mA with a software configurable over-current limit. It can also be disabled for applications requiring an external power conditioner.
The PA Link can synchronize to an NTP Server allowing for automatic time synchronization. The PA Link can synchronize to an NTP Server allowing for automatic time synchronization. It also supports an onboard non-volatile event log for improved fault finding.
The PA Link supports module redundancy allowing two PA Link masters to be connected to the same PROFIBUS PA segment in a one-active-one-standby strategy.
The module hosts two Ethernet ports which can be configured in a Device Level Ring or Linear topology.
Configuration is achieved using Aparian's free downloadable Slate configuration environment. Slate generates PROFIBUS PA device specific UDTs and mapping code which can be imported into Studio 5000, allowing even complex systems to be configured in minutes.
The PA Link also provides DPV1 communication allowing the user to exchange DPV1 Class 1and Class 2 data with each slave device. The PA Link Gateway DTM can be used to configure and parameterize each slave device using Device Type Manager (DTM) technology.
The PA Link will allow the user to monitor and extract DPV1 alarms from each slave device on the connected PROFIBUS PA fieldbus.
The PA Link provides a range of statistics and tools to provide a detailed diagnostic overviewof each PA Link which speeds-up fault finding. The Slate configuration utility allows the user to perform a PROFIBUS PA packet capture of the running fieldbus which can be used to analyse the bus behaviour and packets received. The PA Link also provides global and device specific statistics.
