Patlite Expands LR5-LAN Signal Tower Series, Adds EtherNet/IP Models

Patlite has added EtherNet/IP (LR5-I) models to the LR5-LAN Ethernet signal tower lineup, giving more options for connecting to PLC-based factory automation systems. The new models support EtherNet/IP natively and still offer direct LAN control, making them a good fit for smart factories and industrial IoT setups that want simpler wiring and quicker setup.

Expanded Line Targets PLC-Centric Automation Systems

The new EtherNet/IP-specific models are featured as an addition to Patlite’s LR5-LAN signal tower series. This update is aimed at facilities that use EtherNet/IP for device communication, so signal towers can now work as network devices instead of just standalone I/O units.

A key benefit of the new EtherNet/IP model is its support for EDS files, which store device configuration details. Users can import the EDS file into PLC software and set up the device using the usual network setup steps, instead of writing custom ladder logic or entering parameters by hand.

Typical steps include setting network details like IP addresses, importing the EDS file, adding the device to the PLC project, and controlling the signal tower through EtherNet/IP. This process saves engineering time and helps prevent setup mistakes.

Direct LAN Control Replaces Traditional I/O Wiring

Previously, many industrial PC-based systems needed digital output boards to control signal towers and buzzers, which added more parts and made spare part management harder. Patlite’s LR5-LAN series lets users control lights and sounds directly over the network using HTTP(S), Modbus/TCP, or EtherNet/IP.

The LR5-LAN works with several communication protocols to fit different needs. The EtherNet/IP models are made for PLC integration, while the standard LR5-LAN units support Socket communication, Modbus/TCP, and HTTP(S). This flexibility means the new signal towers can be used with PLCs, industrial PCs, and higher-level systems like SCADA and production management platforms.

Designed for Smart Factory and IIoT Environments

The LR5-LAN series is designed for smart factories and industrial IoT applications. It includes a built-in web server so users can set it up in a browser and change settings without extra software. The signal towers are rated up to IP65 for protection, helping them work reliably on the factory floor. Central control of LED lights and alarms keeps status signals consistent across production lines. This solution provides signaling for industries such as semiconductor, automotive, and chemical, as well as notifications for upper-level SCADA systems.

To make software development easier, the LR5-LAN offers a browser-based command generation feature. After logging into the signal tower, users can choose the desired operation from a setup screen, which automatically creates control commands. This allows users to verify behavior without needing to check manuals. Sample source code is available in several programming languages for both Linux and Windows, making integration and testing faster. The solution also includes seven preset LED flashing patterns, so flashing can be controlled with simple commands instead of PLC timing logic.

Expanding Network-Based Signalling on the Factory Floor

The new LR5-LAN uses the same stackable modular design as other LR series signal towers. Users can easily change the order of the LED colors without tools, allowing flexible customization for different needs. Patlite’s addition of EtherNet/IP-compatible models to the LR5-LAN series extends network-based signaling to more factory systems, reduces wiring complexity, and improves visibility of machine and system status, all of which are important features for the constantly evolving modern smart factories.
