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.

The 1756 PMIO Scanner will slot into a ControlLogix backplane and provide input and output assemblies which are mapped  to various Honeywell TDC 3000® IO Processors (IOPs) allowing the Logix controller to own and control the legacy IO.

The PMIO Scanner also supports Honeywell TDC 3000® IO redundancy by providing two Honeywell IO Link connections via the two 3-way connectors on the front of the module.

The PMIO Scanner supports 3 Modes ofoperation:

  • Run   - PMIO Scanner configures IOP, reads inputs & controls outputs
  • Shadow  - Listen only, provides Input & Output Readback values to Logix for checkout/testing
  • Learn  - Uploads configuration from existing pre-configured IOPs

Options to Add & Configure IOPs:

  • EB (Exception Build) File Import
  • Online Learn Option
  • Manual Configuration

Within the Slate environment each IOP can be configured to match the application.

The following IOPs are currently supported:

  • HLAI6 – High Level Analog Input Processor (16 channel)
  • AO16 – Analog Output Processor (16 channel)
  • DI – Digital Input Processor (32 channels)
  • DO16 – Digital Output Processor (16 channel)
  • DO32 – Output Processor (32 channel)
  • AO8 – Analog Output Processor (8 channel)

The configuration of the IOPs and their respective IO points (channels) can be configured manually, imported from Honeywell EB (Exception Build) files, or scanned from an online Honeywell system.

To aid in migration, the PMIO Scanner provides a number of Operational Modes, including a Shadow mode where the PMIO Scanner can run in parallel with the HPM. In this mode the APM/HPM is controlling the IOPs and the PMIO is listening-in and providing the input data to the ControlLogix.



The ControlNet Router provides an efficient method of bridging between ControlNet and Ethernet networks.

The module exchanges data with a Logix controller via a ControlNet bridge (eg. 1756-CNB) using Scheduled Class 1 communication or Unscheduled Class 3 / UCMM messaging.

The size of the produced and consumed data is user-configurable up to 400 bytes.

The IO data can be accessed via Ethernet using either the PCCC or EtherNet/IP protocols. The former allows the module to emulate user-defined PLC5-type data files simplifying the data exchange with PanelViews .

The ControlNet Router is easily configured using the Aparian Slate environment. RSNetworx for ControlNet is used to scheduled the ControlNet Router over the ControlNet network.
