Great Solutions for Allen-Bradley Migrations

SoftPLC's Allen-Bradley Remote I/O (RIO) and Data Highway Plus (DH+) Gateways allow you to upgrade your outdated Allen-Bradley PLC-based control systems in phases - eliminating the need to obtain major project funding and scheduling a lengthy downtime for a complete replacement. Our migration solutions are suitable whether you want to continue to use Rockwell Automation products, or move to another vendor's products. SoftPLC Gateways are perfect solutions when you want to:

Replace Obsolete Components

  • Replace drives (eg: 1336/1395 VFD's) on an Allen-Bradley RIO network
  • Replace HMI's (eg: PanelView) or SCADA systems on Allen-Bradley RIO or DH+ networks
  • Replace robots, scales or other equipment on an Allen-Bradley RIO or DH+ network
  • Replace an A-B PLC, while still maintaining existing DH+ communications
  • Replace an A-B PLC CPU, without changing anything else
  • Replace an A-B PLC with a DCS or other brand controller, without changing the RIO
  • Replace RIO/DH+ cabling without changing PLC's or RIO

Expand Existing Systems

  • Connect new and old systems to a common network
  • Communicate data between devices on different network types
  • Add I/O from another vendor to an existing A-B PLC system
  • Add A-B I/O to an existing A-B PLC system

The Applications tab below provides additional examples of how SoftPLC A-B RIO/DH+ Gateways can be used.

Here's a short video that describes how SoftPLC Gateways solve A-B migration challenges:


    RIO/DH+ Gateways

    Overview

    Protocols implemented via "blue hose" port(s)*

    • A-B RIO Master (Scanner)
    • A-B RIO Slave (Adapter)
    • A-B Data Highway Plus (DH+)

    * These protocols require factory installed hardware.

    SoftPLC Gateway ports and protocols are configured with TOPDOC NexGen, included free with your first Gateway purchase. Communication drivers are configured with an easy to use editor, that includes a sample template. Many drivers also report status to diagnostic registers that are available to HMI's, other connected devices, email messages/reports, etc.

    SoftPLC Gateway Models

    All SoftPLC Gateways provide a base set of features, the differences are primarily in the number of communication ports. Detailed information and specifications on all standard models can be found here: SoftPLC Gateways. For "bluehose" RIO/DH+ gateways, we offer 2 models - Smart Gateways and NeoPACs.

    SoftPLC Gateways are, in reality, SoftPLC controllers. For more details on advanced features, additional hardware/firmware options and available accessories, refer to SoftPLC Controllers and universal SoftPLC features information.

    Smart Gateway

    Smart Gateways

    A Smart Gateway has a base set of features, to which you can add both hardware and firmware options. Smart Gateways are factory assembled with your selected options, then undergo a system-level test prior to shipment.

    All Smart Gateways include this base set of communication ports:
