Reliable radio control in stage technology - "Beauty and the Beast" in Madrid

Numerous moving elements are used in the elaborately designed stage production, which have to interact precisely with each other. They are controlled wirelessly via DATAEAGLE 3000 Wireless PROFIBUS, which ensures reliable communication between the control system and the stage mechanisms. Even the smallest signals - such as the opening of a gate at exactly the right time - must be transmitted without errors to ensure that everything runs smoothly on stage.

Initially, low-cost radio systems from a well-known competitor were used. However, it became apparent during commissioning that this solution could not guarantee the necessary availability. Despite the supposedly simple task - the transmission of a single bit to control a stage element - Profibus errors occurred time and again. This was unacceptable for the actors and the technical team, because in a live situation, every signal has to be correct.

Fülling + Partner Ingenieurgesellschaft therefore opted for the DATAEAGLE Wireless PROFIBUS system from Schildknecht AG. This system impresses with its patented data pre-processing, which intelligently prepares incoming signals before they are sent. As a result, the wireless connection remains stable and fail-safe even in environments with many potential sources of interference. Bus errors, which occurred with other systems, are now a thing of the past.

• PROFIBUS radio data transmission system
• DATAEAGLE 3703 radio module

Since using the DATAEAGLE radio solution, the control of the moving stage elements has been absolutely reliable. Every signal is transmitted precisely at the right moment - even with high levels of radio interference in the surrounding area. As a result, the solution not only ensures greater safety and stability during operation, but also what is important in show business: perfect staging.
