The SmartTILE-Fx (Smart TRi Integrated Logic Engine) is the brain board used on the TRi proven, top-of-the-line Fx-series Super PLCs since 2008. Beginning from 2014, TRi also offers SmartTILE-Fx to small, medium, and large OEM equipment makers to easily build their own private-labeled, low cost, network-ready Super PLC that harnesses all the flexibility and ready-made tools of an industrial grade Super PLC, and yet purpose-built to fit their equipment perfectly. Tens of thousands of SmartTILE-Fx based custom PLCs have since been reliably controlling equipments 24/7 throughout North America and Europe.


  Six Reasons Why You Should Build Your Own Custom PLC


Explore our FREE OEM Tools that help equipment makers deliver services, such as remote/protected software upgrades.

Smarttile Development Kit

Step 1: Choose a Development Kit

Each kit includes:

  • Fx1616-BA or Fx2424 SmartTILE-based PLC (two kit options)
  • SmartTILE (additional unit), Software License
  • USB to RS485 adapter for serial port development and testing
  • Software License for i-Trilogi (compatible with all TRi PLCs and SmartTILE)
  • Pin sockets for SmartTILE
  • Complete SmartTILE Design Guide

Step 2: Design a Carrier Board

  • Use our design services, or design in house
  • Create a board with I/O YOU need
  • Even have multiple versions using the same SmartTILE brain board
  • Integrate sensors and/or conditioners to reduce external components and cost
  • Private-lable the controller to make it YOURs

Step 3: Program Your Custom PLC

  • Use our standard i-Trilogi ladder logic + TBASIC programming environment
  • Avoid trying to utilize complex low-level languages
  • Simple yet powerful ladder logic and TBASIC structured text programming
  • Our PLC programming software is industry proven
  • Start with evaluation version and build on it as you design the hardware
