Smart Gateway Overview

Multi-protocol gateway, data logger, virtual HMI

A complete solution for industrial data communication and management! Smart Gateways are the most powerful and flexible communication protocol converters, bridges, and data concentrators available.

  • Protocol Bridge - Read/Write data between up to 16 simultaneous networks. Virtually unlimited data capacity.
  • Data Logging - Store time-stamped information in choice of file formats. Store data locally, on a network drive or in the cloud.
  • Alarm Notification - Send email or text messages. Highly customizable alarm triggers and list of recipients.
  • Reporting - Generate text or CSV reports. Send reports or data logs as email attachments, or store on any accessible drive.
  • Remote Access/Control - Embedded web server provides ability to view and change data values/states via web pages.
  • Virtual HMI - Embedded Web Studio runtime provides HMI functions, including sophisticated alarm managment, real-time trending, remote SQL database interface and more.

Smart Gateways are ideal for moving data between equipment controlled by different vendors, providing a path for staged migration from older technology based on proprietary networks to new and ethernet-based systems, or combining data from multiple networks to a single ethernet/cellular channel for data analysis or other high-level systems, plus many other applications.


  • (4) port managed Ethernet switch/router, user-configurable protocols
  • (6) serial ports, user-configurable protocols
  • Options for added internal hardware interfaces for protocols such as A-B DH+, A-B RIO, CAN/J1939 and more
  • Supports up to 16 simultaneously active user-selectable Ethernet/serial/proprietary protocols to hundreds of I/O products, devices and networks
  • 63MB RAM user memory, up to 100M words data registers for mapping, plus logic
  • 128MB compact flash (expandable to 8GB) for applications, web pages and data logging
  • Extensive logic capability for data concentration, scaling, mapping between networks, and more
  • Alarm notification via email or text message, reports/logs can be sent via email attachments
  • Embedded web server option with read/write data ability
  • Embedded virtual HMI option for operator interface via any web browser, remote SQL database interface, and more (Web Studio runtime)

Ordering Information

  • Note: Smart Gateway uses TOPDOC NexGen software for configuration. A free TOPDOC NexGen license is included with your first Smart Gateway purchase!
  • All Smart Gateways include all supported serial and ethernet protocols as standard, configurable in any mix. If you desire support for Allen-Bradley Data Highway Plus (DH+), Remote I/O (RIO) and/or CAN, these must be factory installed - specify them above for COM5 and/or COM6 options.
  • COM6 options (except the phone modem) require purchase of the SM-COM6CBLTB to provide a terminal block interface for field wiring.
  • Select the desired remote access and/or virtual HMI features. If the remote access connection will be other than wired Ethernet, an external modem/interface is required. See Modems/Wireless for options, or contact SoftPLC to discuss TagWell cloud-based solutions and approved third-party interfaces.
  • The Gateway Size only applies if you are using ModbusTCP Master, Ethernet/IP, A-B RIO or DH+ protocols. Select the Lite (LT) version if you are not using these protocols.

    The Gateway Size determines the maximum number of ModbusTCP server connections, Ethernet/IP tags and Allen-Bradley logical I/O racks supported (I and O addresses). (All Gateway Sizes support up to 254 ModbusTCP client connections when the Gateway acts as a ModbusTCP Slave, and unlimited data points for all protocols.) The table below summarizes the available sizes:
