Low cost, powerful A-B gateways

Solutions for Allen-Bradley Remote I/O and Data Highway Plus Migrations

SoftPLC Gateways allow you to upgrade your outdated Allen-Bradley PLC-based control systems in phases - eliminating the need to obtain major project funding and scheduling a lengthy downtime for a complete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 VFD) on an Allen-Bradley RIO network
  • Replace HMI's (eg: PanelView) on Allen-Bradley RIO network
  • Replace HMI/SCADA on a Data Highway Plus network
  • 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, 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 System

  • 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

    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.

    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 9 communication ports:

    • 4-port 10/100MB managed Ethernet switch with two Ethernet interfaces (MAC ID's) to support routing and firewall functions
    • (1) RS-485 + (4) RS-232 serial communications ports

    For very low cost, these factory installed communication port options are also available:

    • Allen-Bradley Remote I/O Master or Slave (Up to 2 ports - replaces COM5 and/or installs at COM6)
    • Allen-Bradley Data Highway Plus (Up to 2 ports - replaces COM5 and/or installs at COM6)
    • Additional RS-485 port, with 2 and 4-wire support (installs at COM6)
    • CAN / J1939 (installs at COM6)

    It's easy to choose options and price your Gateway using our webstore ordering page, or you can contact us for assistance.

    SoftPLC NeoPAC

    NeoPAC Gateways

    A NePAC Gateway are powerful, low cost RIO/DH+ interfaces. NeoPAC Gateways are factory configured with your selected options, then undergo a system-level test prior to shipment.

    NeoPACs provide these communication ports:

    • (1) GB Ethernet port
    • (1) RS-485 serial communications port
    • (1) RIO/DH+ "bluehose" port
    • (2) USB ports

    It's easy to choose options and price your Gateway using our webstore ordering page, or you can contact us for assistance.

    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.
