WERMA Signaltechnik is a leading manufacturer of signalling solutions, with crafting new and innovative solutions to make applications more efficient and reliable. WERMA Signaltechnik have introduced a new innovative version of their most successful signal tower… the eSIGN.
Intelligent signal tower for PROFINET networks
The WERMA eSIGN signal tower with PROFINET and PoE is the perfect solution for extending your industrial Ethernet network to include visual signaling. By integrating directly into the network, it eliminates the need for extra I/O modules and allows for direct PLC control. This ensures all status messages and process warnings are displayed with real-time accuracy.
ADVANTAGES OF PROFINET INTEGRATION
- Direct integration into existing PROFINET infrastructures
- Real-time signal transmission
- Central control via PLC/controller
- Fast project planning in common engineering tools
- Extended diagnostic options via the network
- Reduction in additional hardware components
- High investment and future security
- Improved integration options and maximum flexibility
What would be more innovative than the eSIGN?
WERMA have introduce a new version featuring PROFINET interface. The eSIGN series is already much more than a classic signal tower – it is a powerful visual communication system for machines, plants, and production environments. The company’s core product offers even more flexibility for integration into complex environments, this once again shows what WERMA signal technology provides within modern applications.
More Colours… More Freedom. 
With the classic signal tower getting an upgrade users can experience excellent LED technology with freely programmable colours and light effects, full- surface signalling and an modern industrial design that won the "iF design award 2025. With the new PROFINET version, development is now continuing consistently – towards a fully networked, real-time communicating signalling solution for Industry 4.0.
Real-time communication and Power over Ethernet
WERMA eSIGN PROFINET enables users to see real time communication between the signal device and the control system. Machine statuses can thus be displayed and evaluated without delay – a decisive advantage in automated and safety-relevant applications.
In addition to this, the signal tower is powered via power over etherne (PoE), meaning that data and energy are transmitted via single cable. By having this innovative feature this reduces installation costs and material costs whist ensuring a tidy, efficient system layout. The eSIGN PROFINET supports both PoE and PoE+ and is connected via a 4-pin M12 socket – robust, industry-standard, and future-proof.
Easy commissioning – intelligent diagnostics
Incorporating the new eSIGN is extremely easy, by simply connecting the device and it ill automatically recognised by the network. The signal tower can be integrated directly into the existing network topology.
The PROFINET version offers extended diagnostic options – errors in communication between the product and the control system are detected more quickly and localized more precisely.
This allows the causes of errors to be traced immediately, which noticeably simplifies maintenance and service and increases system availability.
Even more flexibility in control. Compared to the IO-Link version, WERMA new PROFINET variant offers even greater flexibility. Users can switch between all modes and colours and control each segment individually – ideal for dynamic processes in which statuses, warnings, or process progress must be visualized precisely.
This makes the eSIGN PROFINET not just a signal source, but an intelligent communication module that integrates seamlessly into any industrial environment.
PROFINET or IO-Link – complete freedom of choice for every application
WERMA customers can now choose between two powerful communication interfaces. The IO-Link version is optimized for machine-level control, while the new PROFINET model empowers large-scale industrial networks with real-time connectivity, integrated diagnostics, and simplified PoE installation.
Future-proof signalling technology – developed for Industry 4.0
WERMA continues to lead industrial innovation with the launch of its PROFINET-compatible eSIGN. This modular, networked system defines the future of signalling—delivering the uncompromising reliability and seamless communication required by today’s high-tech environments.
