Core Features & Benefits

1. Sampling Trace Function

    * Reduced Startup & Troubleshooting Time: This function aids in analyzing data during faults and verifying program debugging, significantly shortening equipment diagnosis and system startup periods.

    * Multi-CPU System Analysis: It is particularly useful in multi-CPU systems for measuring and verifying data exchange times between CPU modules.

    * Advanced Data Visualization & Analysis: Captured data can be analyzed using programming tools (e.g., GX Works2) and displayed in user-friendly formats like charts and trend graphs for both bit and word device data.

    * Data Export & Logging: Sampling trace results can be saved as CSV files compatible with GX LogViewer, enabling detailed display and analysis using this dedicated data logging tool.

2. High-Speed Processing for Enhanced Performance

    * Shorter Cycle Times: Supports the reduction of overall system scan time, which is crucial as applications grow larger and more complex. This is achieved by leveraging the high-speed basic instruction processing performance (e.g., 1.9 ns) of compatible Q Series CPUs.

    * Improved System Performance & Stability: Enables high-speed control traditionally associated with microcontrollers while minimizing performance deviations, leading to higher system throughput and shorter production cycle times.

3. Enhanced Capacity & Ease of Programming for Large Data Handling

    * Simplified Large-Capacity Data Management: When used with high-performance Q CPUs (like the High-Speed Universal QCPU) equipped with an 8 MB SRAM expansion card, the standard RAM and SRAM card file register areas can be accessed as a single, continuous file register space. This eliminates the need for programmers to manage boundaries between memory areas.

    * Expanded File Register Capacity: Total file register capacity can be expanded up to 4736K words, easily overcoming soft element memory limitations by installing an extended SRAM card.

    * Advanced Index Register Functionality:

        * Index registers are expanded to 32-bit, allowing programming to extend beyond the traditional 32K word limit.

        * Index modification (indexed addressing) is now supported across the entire file register area.

        * The processing speed for index modification has been increased, which is critical for efficient operations on structured data (arrays).

        * When used within loop structures (e.g., FOR-NEXT instructions), faster index modification contributes to reduced program scan times.

Typical Applications

Ideal for automation systems requiring high-density DC output, fast response, and reliable operation in industries such as packaging, material handling, assembly lines, and machine tool control, especially where system diagnostics, rapid startup, and handling of large data arrays are priorities.
