Product Description

The MFP module is characterized by its dual-domain architecture:

• Real-Time Control Domain (RTD): This domain is dedicated to executing the standardized PLC program (e.g., using Ladder Logic or SCL) with deterministic cycle times and guaranteed real-time performance. This core handles all critical I/O, safety, and motion control tasks.
• High-Level Language Domain (HLLD): This domain runs a separate, often Linux-based, operating environment that is shielded from the RTD. It allows users to execute High-Level Language (HLL) applications (e.g., C/C++, Python, or custom executables) that require complex data processing or advanced connectivity.
• Data Exchange: The two domains communicate via a fast, internal mechanism or shared memory, ensuring seamless, high-speed data exchange without relying on external network protocols.

Product Parameters

Key performance and technical parameters for MFP modules include:

• Architecture: Multi-core processor design, with cores dedicated to the PLC task and the HLL application environment, respectively.
• Memory: Significantly large and segmented memory space, with dedicated memory partitions for the PLC program/data and the HLL application’s OS, libraries, and runtime environment.
• Processing Speed (RTD): Extremely fast processing times for standard bit and word instructions to maintain real-time performance in the control domain.
• HLL Environment: Supported operating system (e.g., Linux) and development environment for non-PLC code execution.
• Integrated Interfaces: Multiple high-speed network interfaces (e.g., PROFINET IO RT/IRT) for standard automation traffic, plus potentially separate interfaces for the HLL domain’s IT connectivity.
• Data Communication: Guaranteed maximum bandwidth and latency for internal data exchange between the RTD and HLLD.

Product Advantages

The integration offered by the MFP module provides powerful benefits:

• Consolidation and Cost Reduction: Eliminates the need for a separate Industrial PC (IPC) to handle data processing tasks, saving hardware, cabinet space, and cabling costs.
• Performance Offloading: Complex, non-deterministic tasks (such as sophisticated data calculations, custom communication stacks, or image processing algorithms) are offloaded to the HLLD, freeing up the PLC core to maintain its critical, deterministic cycle time.
• Flexibility and Customization: Engineers can leverage standard HLL programming tools, libraries, and open-source software, providing immense flexibility for specialized functions that are difficult to implement using traditional PLC languages.
• Secure Integration (Domain Separation): The deterministic PLC control is protected from stability issues or security risks arising from the non-deterministic HLL application, as the two environments are logically separated.
• High-Speed Data Access: Enables faster, more direct data transfer between the control system and external applications compared to standard network communication.

Precautions and Notes

Due to its complexity and connectivity, specific attention is required:

• Dual Expertise: Requires personnel who possess knowledge in both industrial automation (PLC programming) and IT/software development (High-Level Language programming and OS management).
• Security Management: The HLL domain, often running an open OS like Linux, introduces potential IT security vulnerabilities. A robust Industrial Security concept (including network segmentation, strong firewall rules, and mandatory OS/library patching) is critical.
• Resource Allocation: Proper management of CPU and memory resources is required to ensure that the HLL application does not inadvertently impact the performance or stability of the real-time PLC task.
• Intended Use: The module must only be used for the applications described in the relevant technical documentation. All environmental and installation guidelines must be strictly followed.

Product Applications

MFP modules are deployed in high-end, data-intensive automation scenarios:

• Edge Computing and Data Pre-processing: Running advanced algorithms to filter, compress, or analyze large volumes of sensor data directly at the machine before transferring it to the cloud or MES/ERP systems.
• Custom Communication Stacks: Implementing proprietary or non-standard protocols (e.g., OPC UA client/server, specific IT protocols) that are not natively supported by the standard PLC operating system.
• Complex Process Algorithms: Executing sophisticated mathematical models, advanced control algorithms, or predictive maintenance models using HLL libraries.
• Image Processing and Vision Systems: Running compact vision applications or processing data from high-resolution cameras for quality control or robotic guidance directly on the processor.
• Interfacing with IT Infrastructure: Providing a secure gateway between the operational technology (OT) network and the enterprise IT network.
