Rack-free modular controller


The L series is a powerful but compact modular controller with many features built-in to the CPU itself. With its excellent cost performance and usability it is ideal for use in mid-size control applications.

High system flexibility

The rack-free design promotes high system flexibility with minimum form factor. The single-CPU architecture includes built-in Ethernet and Mini-USB interfaces, a SD/SDHC memory card slot for program storage and data logging, and 24 digital I/O for simple high-speed counting and positioning functions. The high-performance CPU also includes a CC-Link V2 Master/Local station for connection to the powerful open field network CC-Link.

Besides the functions already built-in, the CPU can be supplemented with up to 10 extension and special function modules for additional digital and analog I/Os, highspeed counters, communications interfaces, Simple Motion, positioning etc.

The compact size, easy expandability, networking capabilities, and multitude of built-in high-powered functions makes the L series ideal for both stand-alone machines as well as networked stations in larger applications.

Data logging

The built-in data logging function provides an easy way to collect information for troubleshooting, performance evaluation, and other uses. The included configuration tool makes setting up the data logging function a breeze with a step-by-step wizard like interface. Using GX LogViewer, the captured data is easy to interpret and understand.

USB and Ethernet as standard

The built-in USB 2.0 port or Ethernet interface can be used to connect directly at the installation site. The Ethernet interface supports direct connection and does not require any configuration of the PLC or PC to operate.

Advanced programming software

GX Works2 represents the next generation in PLC maintenance and programming software and is perfectly suitable for the L series.
