The Siemens Logo! (Steuerung) is a compact logic controller designed for small automation tasks, aiming to simplify the complexity of traditional relay and timer systems. It’s a programmable brain that replaces multiple relays and timers with one device, freeing up panel space and simplifying troubleshooting. The Logo! is backed by Siemens AG, a well-established name in industrial automation, and has become a standard in workshops, plant rooms, and control cabinets worldwide.
The Logo! is approachable, modular, and can communicate with other devices, making it an ideal solution for small automation projects. It’s designed for applications such as controlling lighting scenes, managing pump and fan sequences, gate and door control, irrigation systems, and simple conveyor or machine automation. The device is programmable using the Logo! Soft Comfort software, which features a drag-and-drop interface with intuitive function blocks.
Users praise the Logo! for its rock-solid reliability, beginner-friendly interface, and great performance in one-off or custom projects. However, some critics note that it may not be suitable for very complex systems and that the software can be limited. Despite this, the overall sentiment is positive, with many users appreciating the device’s dependability and flexibility.
The Logo! competes with other smart relays and mini-PLCs, as well as full-size PLC systems and DIY microcontroller projects. However, its industrial-grade design, long-term reliability, and support from Siemens AG set it apart from hobbyist solutions. The device is an attractive choice for installers and OEMs who need to support their systems for many years.
In conclusion, the Siemens Logo! is a reliable and flexible controller that’s perfect for small automation projects. It’s a great solution for those fighting with panels full of mechanical relays, hard-to-modify timer chains, or small projects bloated by overspec’d PLCs. With its compact, modular design and visual programming environment, the Logo! is an excellent choice for anyone looking to simplify their control systems and improve their overall automation experience.
