This article highlights the technical features, applications, and benefits of this control center.

Node-RED: Intuitive Automation with Serial Interface

The rule.box RS232/422/485 comes pre-installed with Node-RED, an open-source development tool that has been used since 2013 for IoT and automation applications. Node-RED enables creation of automation workflows by dragging connections between input, output, and processing nodes in a browser-based editor. This intuitive user interface requires no deep programming knowledge, making the rule.box especially attractive to users without extensive programming experience. The switchable serial interface (RS232/422/485) enables connection of serial end devices such as measuring instruments, controllers, or modems that communicate via standardized serial protocols. For example, users can read data from a serial sensor to monitor process parameters or send control commands to a serial device to operate machines. Pre-installed nodes allow direct connection of Wiesemann & Theis devices such as Web-IOs, Web thermometers, and Com servers to read and control data such as temperature, switch states, or serial signals. The range of installable additional nodes permits integration of devices from other manufacturers, such as IoT sensors, cloud services, or protocols like Modbus. The created flows are executed energy-efficiently and reliably, making the rule.box an efficient solution for complex automation tasks.

Interfaces and Connectivity

The rule.box RS232/422/485 features a network interface that enables easy integration into existing networks. This interface supports communication with a wide variety of devices and systems, making the rule.box a central control center for IoT and automation projects. The switchable serial interface (RS232/422/485) offers flexibility for connecting devices with different serial protocols, such as RS232 for short distances, RS422 for point-to-point connections, or RS485 for multipoint networks. This interface is suitable for applications in industrial automation, where serial devices are widespread. Pre-installed nodes for Web-IOs, Web thermometers, and Com servers from Wiesemann & Theis enable seamless connection of these devices. Installable nodes extend compatibility to devices from other manufacturers, such as sensors or cloud services. Integration of non-public nodes is available upon request, enhancing flexibility for specific applications. Data access and configuration are done via an internal web server that provides web-based management. Commissioning is quick via WuTility, a tool that enables configuration in just three clicks.

Power Supply and Energy Efficiency

The rule.box RS232/422/485 offers flexible options for power supply, including Power over Ethernet (PoE) and external supply via screw terminal connection. PoE supports phantom power over data pairs as well as power supply over unused wire pairs, simplifying installation in networks without separate power. Buffer capacitors ensure controlled shutdown when disconnecting from the power supply, preventing data loss. The energy-saving architecture, supported by Node-RED’s efficient flow execution, minimizes power consumption and makes the device environmentally friendly. These features are especially advantageous in applications where energy efficiency and reliability are critical, such as building automation or production environments.

Please note: NO power supply is included in the scope of delivery.

Data Processing and Visualization

The rule.box RS232/422/485 enables data storage via a file system, MariaDB, or SQLite, allowing flexible data management for automation projects. For example, data from serial devices such as measurement values or control commands can be stored in a database and used for analysis or long-term monitoring. The Node-RED dashboard offers a user-friendly way to visualize data and automation workflows. Users can create dashboards to display real-time data such as serial measurement values or switch states from Web-IOs and control devices directly via the interface. This functionality makes the rule.box ideal for applications that require both data processing and user interaction, such as in smart buildings or Industry 4.0.

Standard Compliance and Reliability

The rule.box RS232/422/485 meets stringent standards for immunity (EN 61000-6-2) and emissions (EN 55032:2015 + A1 Class B, EN 61000-3-2, EN 61000-3-3), qualifying it for use in residential, commercial, and industrial environments. The high immunity ensures reliable operation even in environments with electromagnetic interference, such as production facilities. The CE marking and UL approval confirm suitability for international applications, while the robust design is engineered for continuous operation. With a five-year warranty, the rule.box offers a low-maintenance and durable solution for professional users.

Versatile Applications

The rule.box RS232/422/485 is ideal for automation in building automation and Industry 4.0. It is especially suitable for scenarios where serial devices need to be centrally controlled, such as measuring instruments, controllers, or modems. For example, users can read data from a serial temperature sensor to control the air conditioning in a building or send serial control commands to a machine. The connection of Web-IOs, Web thermometers, or Com servers as well as devices from other manufacturers via installable nodes makes the rule.box a universal control center for IoT projects. The wide operating temperature range and flexible power supply enable use in demanding environments such as production halls or data centers. Easy commissioning via WuTility and web-based management significantly reduce configuration effort.
