New Patlite LR5-LAN smart factory signal lights with EtherNet/IP support
09 March 2026
The LR5-LAN series is designed specifically for smart factories and IIoT platforms. With direct LAN control via HTTP(S), Modbus/TCP or EtherNet/IP, this product line centralizes both light and sound signaling. The built-in web server and high protection class (IP65) combined with a simplified system design significantly minimizes the requirements for field maintenance.
Direct LAN control is performed by industrial computers (IPCs) and programmable logic controllers (PLCs). The new dedicated EtherNet/IP model enables even more intelligent and easy-to-implement light and sound signaling.
A smart solution to a traditional challenge
PC-based industrial systems have until recently relied on digital output interface boards, and the increased number of components has seriously complicated supply and inventory management.
With support for HTTP(S), Modbus/TCP and EtherNet/IP, Patlite signal lights and sounders can now be controlled via the network architecture, eliminating the need for output interface modules. Configuration via a web browser further simplifies design and maintenance.
LR5-LAN EtherNet/IP models – with integrated control and data acquisition for complex industrial automation applications in digitalized factories;
LR5-LAN models – with direct LAN control via industrial computers and PLC controllers, simplified configuration and easy notification setup.

Leading advantages and capabilities:
- Easy setup – support for EDS (Electronic Data Sheets) files and registration in the PLC software;
- Simplified software design – automatic command generation function and sample source code with support for multiple programming languages under Windows and Linux;
- Wide range of predefined light patterns – seven ready-made LED flashing modes;
- Advanced indication of machine status and higher-level system functions;
- Minimized requirements regarding I/O architecture;
- Visualization of status indications and warnings from SCADA systems and production management platforms via standard protocols;
- Monitoring of host device connectivity – in case of loss of communication, the LED module displays an immediate warning.

Key applications:
- Semiconductor manufacturing;
- Automotive industry;
- Chemical and pharmaceutical industry, etc.
