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 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.
