The Valmet A413045 is a high-performance industrial control CPU module designed for the Valmet DNA distributed control system. Serving as the central processing unit for automation applications, this module delivers robust real-time computing capabilities for demanding process industries including pulp and paper, metallurgy, and power generation.
The A413045 is built around an ARM Cortex-A72 quad-core processor operating at 1.8 GHz, providing substantial computational power for complex control algorithms. The module is equipped with 2 GB of DDR4 RAM and 8 GB of eMMC storage, expandable to 32 GB for application-specific requirements. This architecture supports simultaneous execution of multiple control tasks while maintaining deterministic response times.
The module supports both soft real-time and hard real-time operating modes. In soft real-time mode, control cycles are executed within 50 ms, suitable for general process control applications. For critical control functions, the hard real-time mode achieves cycle times of 10 ms or less, ensuring precise coordination of high-speed machinery and safety-related functions. The hardware-level time-triggered architecture guarantees deterministic instruction execution.
