WERMA eSIGN signal tower with PROFINET and PoE
The smart signalling solution for Industry 4.0
The combination of digitally configurable LED signalling, direct PROFINET connection and Power over Ethernet (PoE) ensures minimal installation effort and maximum transparency in modern production environments.
Intelligent signal tower for PROFINET networks
The WERMA eSIGN with PROFINET was developed specifically for networked machines and systems. It is integrated directly into the industrial Ethernet and can be controlled from the PLC without additional I/O modules. Status messages, warnings and process statuses are visualised clearly and without delay.
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
Power over Ethernet (PoE) –
Data and power via a single cable
Thanks to Power over Ethernet support, the signal tower requires only a single cable for communication and power supply. This greatly simplifies installation and reduces cabling costs – especially in distributed system structures or retrofit projects.
PoE added value in practice:
- Single-cable solution for power and data
- Significantly reduced wiring effort
- Faster commissioning
- Flexible mounting positions
- Ideal for retrofits and Industry 4.0 upgrades
- Fewer connection errors and lower maintenance costs
Industry 4.0 ready –
transparency down to the field level
In Industry 4.0 environments, consistent data availability and clear visual communication are crucial. The WERMA eSIGN PROFINET signal tower is fully network-compatible and supports digital production concepts, smart factories and networked production lines.
The freely configurable LED segments enable status-dependent visualisation of complex processes – from machine status and escalation levels to Andon or OEE displays. Adjustments are made via software instead of hardware modifications.
Industry 4.0 advantages:
- Network-based signalling in real time
- Flexible segment and colour configuration
- Ideal for Andon and condition monitoring concepts
- Supports digital shop floor transparency
- Scalable for modular plant concepts
Freely configurable LED signalling
The eSIGN signal tower offers segment-controlled LED zones with high luminosity and clear colour representation. Colours, flashing modes and animations can be individually defined to suit the machine, process or company standard.
Typical applications:
✔ Machine and plant status displays
✔ Fault and warning messages
✔ Production progress and material requirements
✔ Logistics and line visualisation
✔ Control station and Andon systems
Efficient, durable and low-maintenance signalling
Thanks to modern LED technology, WERMA eSIGN is energy-efficient and low-maintenance. In conjunction with PROFINET and PoE, it creates a particularly economical signalling solution for mechanical engineering, the manufacturing industry and automated intralogistics.
The WERMA eSIGN signal tower with PROFINET and Power over Ethernet is the ideal choice for anyone who wants to consistently expand their PROFINET environment to include visual signalling – integrated, flexibly configurable and ideal for Industry 4.0 applications.
Frequently asked questions
PROFINET enables direct PLC control without IO modules, real-time communication and advanced diagnostics. The signal tower reduces hardware costs, cabling and commissioning time – ideal for networked production environments.
PoE supplies the eSIGN signal tower with power and data via a single cable. This minimises wiring effort, is suitable for retrofit projects and enables flexible installation in distributed systems.
Yes, up to 9 LED segments can be controlled individually for colours, flashing modes and animations. Suitable for machine status, Andon systems, OEE displays or logistics visualisation – software-based without hardware conversion.
Perfect for mechanical engineering, manufacturing and intralogistics: status displays, fault/warning messages, production progress or control station monitoring. It promotes shop floor transparency in Industry 4.0 environments.
