The GOcontroll Moduline IV delivers precise, synchronized Fountain Show Control by automating pumps, lights, and music with modular, real-time performance.

Creating synchronized water, light, and sound performances requires precise real-time control and reliable hardware. The GOcontroll Moduline IV is a modular embedded controller designed to manage the complexity of Fountain Show Control. It synchronizes pumps, solenoid valves, RGB lighting, and music in perfect harmony. With flexible communication options such as CAN and Ethernet, multiple controllers can coordinate to produce breathtaking water shows—from small decorative fountains to full-scale amusement park attractions.

In Fountain Show Control, every millisecond counts. The movement of water jets, the rhythm of lights, and the beat of the music must align seamlessly. The GOcontroll Moduline IV manages this through real-time processing and modular I/O expansion. Its embedded Linux platform allows custom timing logic to be executed deterministically, ensuring flawless synchronization.

Typical control functions include:

• Coordinating pump speeds for varying water jet heights

• Triggering solenoid valves for rhythmic bursts

• Adjusting RGB lighting intensity and color transitions

• Aligning water effects with audio beats or visual patterns

Whether for architectural fountains or live entertainment installations, this level of precision creates dynamic, visually stunning effects.

The Moduline IV supports up to eight plug-in I/O modules, making it ideal for scalable fountain systems. Each module can be tailored to the hardware setup of the installation:

• Output modules control solenoid valves, high power LED drivers, or frequency inverters for pumps.

• Input modules collect data from pressure, flow, or level sensors.

• 4–20 mA modules integrate analog control for proportional valves or pump feedback loops.

The robust aluminum IP67-rated housing ensures reliable operation outdoors, even under humid and wet conditions. Its vibration resistance and sealed connectors make it perfect for installation near or beneath fountain basins.

The GOcontroll Moduline IV runs on a Linux-based operating system, compatible with MATLAB Simulink and Node-RED for flexible programming.

Using MATLAB Simulink, engineers can design timing sequences for lights, pumps, and audio synchronization using block diagrams. These are then deployed directly to the controller for real-time execution.
Meanwhile, Node-RED allows operators to create visual control flows—ideal for show scheduling, remote start/stop, or interactive displays linked to audience input.

Common control workflows include:

• Beat-synchronized lighting and pump routines

• Sequential startup and safety logic for pumps

• Water choreography triggered by preprogrammed timelines or live music signals

This combination of low-level control and high-level orchestration makes the Moduline IV powerful yet accessible.

Complex fountain installations often require multiple controllers working together. The Moduline IV supports Ethernet, CAN 2.0B, and optional Wi-Fi/Bluetooth interfaces, enabling distributed control across large setups.

Possible configurations include:

• Centralized master controller that synchronizes subordinate nodes via Ethernet

• CAN-based distributed valve control for local pump clusters

• Remote access for diagnostics, updates, or real-time monitoring through secured connections

With deterministic communication and scalable architecture, GOcontroll systems can handle hundreds of lighting channels and valves simultaneously without losing synchronization.

Beyond artistic precision, safety and reliability are crucial. The Moduline IV includes built-in monitoring features that track supply voltages, module temperature, and CPU usage. Users can implement automated shutdown sequences if pressure or water level sensors detect anomalies.

The controller’s modular architecture allows for easy redundancy—one module can take over specific tasks in case of failure, ensuring the show continues without interruption.

GOcontroll’s modularity makes Fountain Show Control highly scalable. A single Moduline IV can automate a compact decorative fountain, while multiple units can form a network for large musical water shows. Configuration changes are simple—just swap I/O modules or update the control logic.

This scalability, combined with reliable performance and easy programming, makes the GOcontroll Moduline IV the ideal backbone for creative water installations worldwide.
