ABB VBS01

Product introduction

The VBS01 is a high-performance safety bus module developed by ABB, specifically designed to enable secure communication between safety-related devices in industrial automation systems. It acts as a central hub for safety data transmission, ensuring that critical safety signals, such as emergency stop commands and safety gate interlocks, are transmitted reliably and in real-time between components like the DSTS104 3BSE007285R1 safety relay and the DC541-CM 1SAP270000R0001 controller module.

This safety bus module utilizes Safety over Ethernet (FSoE) protocol, which provides a dedicated and secure communication channel that is independent of standard data networks. The VBS01 integrates seamlessly with ABB’s safety product portfolio, enhancing the flexibility and scalability of safety systems. By consolidating safety signals onto a single bus, it reduces wiring complexity, simplifies system design, and makes troubleshooting more efficient.

With its SIL 3 and PL e certifications, the VBS01 is suitable for high-risk industrial environments where the failure of safety systems could lead to serious accidents. It ensures that safety functions are coordinated across the entire automation system, providing a robust layer of protection for both workers and equipment.

Core advantages and technical highlights

Secure and reliable communication

The VBS01 employs Safety over Ethernet (FSoE) protocol, which incorporates built-in mechanisms for data integrity checks, error detection, and retransmission of lost data. This ensures that safety signals are transmitted without corruption or delay, even in noisy industrial environments. In a automotive assembly plant, for example, this reliability is crucial when transmitting emergency stop signals from multiple safety relays to the main controller via the VBS01, ensuring that all machines in the line stop simultaneously when a hazard is detected.

Scalable safety networks

The VBS01 can connect up to 32 safety nodes, allowing for easy expansion of safety systems as production lines grow or new equipment is added. This scalability eliminates the need for major rewiring or system redesigns when expanding. For instance, in a food processing facility, adding a new packaging line with its own set of safety devices can be seamlessly integrated into the existing safety network by simply connecting the new safety relays to the VBS01, reducing installation time and costs.

Simplified system integration

By consolidating safety communication onto a single bus, the VBS01 reduces the amount of wiring required compared to traditional hardwired safety systems. This not only saves space in control cabinets but also makes installation and maintenance easier. Technicians can quickly identify and resolve communication issues using the module’s LED indicators, which provide clear status updates on network connectivity and fault conditions. The VBS01 also integrates smoothly with ABB’s standard automation components, such as the 3BHE009017R0102 power supply module, ensuring a cohesive and reliable system.

Typical application scenarios

In a large-scale robotic welding facility, the VBS01 serves as the central safety communication hub. It connects multiple DSTS104 3BSE007285R1 safety relays, each monitoring emergency stops and safety gates around individual robot cells. The VBS01 transmits safety signals from these relays to the DC541-CM 1SAP270000R0001 controller, which coordinates the shutdown of all robots if any safety device is triggered.

During operation, if a worker opens a safety gate in one robot cell, the VBS01 ensures that the safety signal is transmitted to the controller within 10 ms, triggering an immediate stop of all robots in the facility. This synchronized shutdown prevents potential collisions between robots and workers, adhering to strict safety standards. The VBS01 also sends diagnostic data to the controller, allowing maintenance teams to quickly identify which safety device was activated, reducing downtime during investigations.

Powered by the 3BHE009017R0102 power supply module, the VBS01 maintains reliable operation even in the harsh environment of the welding facility, withstanding temperature fluctuations and electromagnetic interference from welding equipment.

Installation, commissioning and maintenance instructions

Installation preparation

Before installing the VBS01, ensure the control cabinet is clean, dry, and well-ventilated. The ambient temperature should be within -25°C to +60°C, with relative humidity below 95% (non-condensing). Required tools include a screwdriver, wire strippers, and a torque wrench.

Mount the VBS01 on a 35 mm DIN rail, leaving at least 15 mm of space on all sides for heat dissipation. Connect the 24 V DC power supply (from a 3BHE009017R0102) to the designated terminals, ensuring correct polarity. Use shielded twisted-pair cables for FSoE communication, with shields grounded at both ends to minimize electromagnetic interference. Connect safety devices, such as the DSTS104 3BSE007285R1, to the communication ports using the appropriate connectors.

Maintenance suggestions

For daily maintenance of the VBS01, check the LED indicators regularly: a steady green power LED and a flashing green communication LED indicate normal operation. A red fault LED signals issues such as communication errors or power loss—refer to the manual to diagnose specific faults.

Test the safety communication network monthly by activating each safety device and confirming that the VBS01 transmits the signal to the controller correctly. Clean the module with a dry cloth quarterly to remove dust. If a fault persists after checking wiring and connections, reset the VBS01 to factory defaults and reconfigure it. When replacing the module, use an ABB-approved spare to maintain safety integrity. Always power down the system before replacing the VBS01 to avoid communication disruptions.
