The Baumüller b maXX PLC di is a drive-integrated programmable logic controller that sets a new standard for decentralized automation. By embedding complex motion control, technology, and control functions directly within the drive, the PLC di enables highly synchronous processes, reduces fieldbus load, and paves the way for modular machine designs. Its open, Linux-based runtime environment and support for modern IoT protocols make it a future-proof solution for demanding industrial applications.

Highly Synchronous Motion Control

The b maXX PLC di excels in applications requiring extreme precision and speed. Thanks to its direct integration in the drive, it achieves minimum cycle times of up to 125 μs. This internal communication path between the PLC and the servo-controller provides "hard real-time" access to drive parameters such as torque, speed, and position. Furthermore, the PLC di can function as an EtherCAT master, allowing it to control other drives on the network and, in many cases, eliminate the need for a separate, higher-level PLC entirely. This reduces hardware costs and simplifies system architecture.

Open System and Advanced Programming

Baumüller embraces open standards with the b maXX PLC di's entirely in-house developed runtime environment. Based on Linux, this platform supports programming according to IEC 61131-3 and also allows the integration of high-level languages like C++. This unique combination offers maximum flexibility, enabling machine builders to implement custom algorithms, protect intellectual property, and seamlessly integrate the controller into diverse IT/OT environments. The openness extends to connectivity, with native support for OPC UA, MQTT, and standard Ethernet protocols, making the PLC di fully prepared for Industry 4.0 and IIoT applications.

Real-Time Communication and Smart Monitoring

Speed is not limited to the control loop. The digital inputs of the b maXX PLC di are designed to react in real-time to critical external events, such as touch probes, ensuring precise synchronization and immediate response. The analog high-speed inputs offer a minimum scanning time of just 1 μs without any additional hardware. This capability enables advanced condition monitoring solutions, like the integrated Smart Vibration Monitoring software, which can detect imbalances or misalignments in motors and pumps directly within the PLC, facilitating predictive maintenance and reducing downtime.

Applications

The Baumüller b maXX PLC di is ideally suited for applications that demand high performance, modularity, and openness:

• Highly synchronous multi-axis applications (e.g., printing, packaging, converting)
• Modular machine designs requiring independent, pre-commissioned modules
• Condition monitoring and predictive maintenance systems (vibration analysis)
• IIoT-enabled machinery requiring OPC UA and MQTT connectivity
• Decentralized control architectures where a central PLC is cost-prohibitive
