Field Logic Controller

Let us be so bold to predict the death of PLCs as we know them

Demonstrating our commitment to flexible, custom solutions, Turck has developed the next big thing for control: the field logic controller (FLC). Turck's FLC solutions are made possible by ARGEE (A Really Great Engineering Environment), a revolutionary web-based programming environment that allows users to set conditions and actions directly at the field level. By utilizing HTML5, Turck provides a complete engineering environment for users to write, run, simulate, debug, and monitor code, all without requiring the use of a PLC.


Using FLCs, Turck's multiprotocol block I/O products can act as simple I/O devices or as standalone logic controllers. While ARGEE programming is not designed to replace a PLC outright, it can be used to change the way we think about control, allowing FLC devices to:
  • Be used without a PLC in standalone applications
  • Perform arithmetic functions, use timers, counters, and even toggle bits
  • Share data with a PLC via assigned I/O variables


Using a simple "Condition" and "Action" principle that is integrated into a flow chart user interface, ARGEE allows users with little or no programming experience to easily configure and program their Turck FLC devices. 

ARGEE challenges what an I/O device can do by creating a hybrid between simple block I/O and higher level PLCs. The result - Turck's FLC.


Added Value at Zero Cost

Turck provides the ARGEE programming environment for free with the block I/O modules TBEN-L, TBEN-S, BL compact, and FEN20. 

This allows us to partner with our customers and push the limits of control.


Industrial Internet of Things Ready

With the extra control intelligence of ARGEE, Turck's block I/O modules are ideally suited for the requirements of IIoT scenarios, as they also support necessary technologies such as Ethernet, IO-Link, and RFID.


Flexible Use Through HTML5

ARGEE is based on the latest web standards of HTML5. All functions can therefore be used with any device that is running an HTML5 capable web browser such as Chrome or Firefox, whether using a PC or tablet. Special software is not required.

Easy PLC Connection

In addition to decentralized logic processing, ARGEE can exchange and process data with higher-level control systems via PROFINET, EtherNet/IP, or Modbus TCP. This allows an FLC to be used for decentralized signal preprocessing.
