Smart SoftPLC Overview

Smart SoftPLC, Backplane3 with Tealware modules

Smart SoftPLC's are versatile Programmable Automation Controllers (PACs). All features of the SoftPLC Runtime Control Software are included. Users have virtually unlimited capacity for program logic and data table, data logging, recipes, etc. Plenty of communication ports with configurable drivers and I/O interface options make Smart SoftPLC's perfect for a wide range of control applications, as well as performing communication gateway (protocol conversion) functions.

  • (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 for virtually unlimited logic and up to 100M words data registers
  • 128MB compact flash (expandable to 8GB) for applications, web pages and data logging
  • Extensive ladder logic capability for control, computations/data manipulation, 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 SoftPLC uses TOPDOC NexGen software for programming, configuration and troubleshooting. A free TOPDOC NexGen license is included with your first Smart SoftPLC purchase!
  • All Smart SoftPLCs 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 any 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 Size only applies if you are using ModbusTCP Master, Ethernet/IP, local Tealware I/O, A-B RIO or DH+ protocols. Select the Lite (LT) version if you are not using these protocols.

    The Size determines the maximum number of ModbusTCP server connections, Ethernet/IP tags, force-able discrete I/O, and Allen-Bradley logical I/O racks supported (I and O addresses). The table below summarizes the available sizes:
