Generic Motion Control (GMC) is a groundbreaking concept introduced by B&R, designed to unify motion control across a wide range of applications. Within the GMC framework, CNC systems and robots are seamlessly integrated into a single, cohesive architecture. This integration is made possible through the advanced capabilities of B PCC, which uses the real-time operating system Automation Runtime to manage multiple tasks simultaneously. These tasks include logic control, hydraulic systems, user interface display, CNC operations, robotic movements, motion control, safety protocols, and communication processes.
Under the GMC architecture, there are no restrictions on the type of actuators used. Customers can choose the most cost-effective execution units based on their specific application needs. Options include asynchronous motors, stepper motors, DC motors, synchronous servo motors, torque motors, and more. This flexibility ensures that the system can be tailored to meet varying performance and budget requirements.
CNC systems under GMC operate differently from traditional setups. Instead of relying on dedicated systems, B Studio provides libraries for developing application interfaces that support both CNC and robotic functions. These include PLCopen standards for motion control, as well as controls for other actuator types such as hydraulics. This approach maintains the familiar software environment of traditional CNC and robot systems while offering greater flexibility and scalability.
The key changes brought by GMC include:
- The elimination of the need for dedicated CNC or robot systems.
- The preservation of traditional operating habits for CNC and robotic applications.
- A fusion of traditional CNC and robotics technology with PLC-based control.
Historically, dedicated CNC systems were developed because traditional PLCs lacked the real-time processing power required for complex CNC and robotic tasks. While PLCs excel in handling logical control tasks, they are not optimized for complex algorithmic computations, which are typically the domain of PCs. GMC leverages the B PCC control system, combining the strengths of both PLCs and PCs.
In essence, the uniqueness of a dedicated system lies more in its software than in its hardware. If the hardware meets the necessary specifications, the software can run across different platforms. This principle makes GMC a versatile and future-proof solution for modern motion control applications.
