Programmable Controller MICREX-SX Series (SPH3300・SPH2200 )

A New Computational Engine-Measurable Speed Gains

Fuji Electric benchmarked SPH3300 and SPH2200 directly against their predecessor CPUs, and the gains are substantial rather than incremental:

• SPH3300 sequence instruction execution: ≥5 ns/instruction-1.8× faster than SPH3000(D) (≥9 ns) and 4× faster than SPH300 (≥20 ns).
• SPH3300 applied instruction execution: ≥4.4 ns/instruction-1.8× faster than SPH3000(D) and 9× faster than SPH300.
• SPH2200 sequence instruction execution: ≥12 ns/instruction-2.5× faster than SPH2000 (≥30 ns).
• SPH2200 applied instruction execution: ≥11.2 ns/instruction-3.5× faster than SPH2000 (≥40 ns).
• Sequence control task execution time: SPH3300 runs a representative sequence application roughly 2.7× faster than SPH3000 and roughly 6.5× faster than SPH300 across the full program memory range.
• Motion control task cycle: for a 40 Kstep program with 10 axes under synchronization control, SPH3300 achieves a default 2 ms cycle (2× faster than SPH3000D's 4 ms default), with a 1 ms fixed cycle option available.

(Fuji Electric notes these are representative values from sample applications, not guaranteed performance, actual results depend on the specific application and memory usage.)

Full Motion Instruction Support Built In

• Supports standard built-in motion function blocks (FBs) and 64-bit operation instructions, previously only available on SPH3000, Das native features, not an add-on.
• SPH3300 controls up to 32 axes at a 2 ms cycle, approximately 2× the axis count of SPH3000 (16 axes/2 ms) and 4× that of SPH300 (8 axes/2 ms).
• Ready-made FB types include PTP (point-to-point) positioning, 2-axis linear/circular interpolation, and flying shear control with main-axis speed control and interval synchronization, covering common packaging, cutting, and conveyance motion patterns without custom low-level code.

Faster Application Downloads

Communication performance improvements translate directly into shorter commissioning and update cycles:

• SPH2200 (32 Kstep program): downloads in about 3.5 seconds, roughly 4× faster than SPH2000's 14.3 seconds.
• SPH3300 (245 Kstep program): downloads in about 17.2 seconds, roughly 13× faster than SPH300's 219 seconds and well ahead of SPH3000(D)'s 44 seconds.

Standard Logging Function for Troubleshooting

• Collects and saves CPU module data (temperature, pressure, distance/displacement, servo speed/torque, work ID/equipment ID, error alerts, and more) at any desired timing, without affecting scan time or machine operation.
• Data is stored to SD card in chronological order and can be played back and analyzed later : including export to Excel or CSV for downstream data analysis : turning post-incident troubleshooting from guesswork into a data-driven review.
• Waveform monitor displays the collected variable data on a time axis, connecting directly to servo systems, proximity switches, displacement sensors, and pressure sensors over the SX bus.
• SX monitor goes a step further, replaying the actual user program logic around a trigger event (pre-trigger, at-trigger, and post-trigger cycles) so engineers can see exactly what the ladder logic was doing when a fault occurred. (SX monitor requires SX-Programmer Expert/D300win.)

Model Transition Function-Migration Without a Rebuild

A four-step, GUI-driven migration path is built into the programming software:

1. From the "Project" menu, select Model Transition.
2. Confirm the project name: overwrite the source project or save under a new name.
3. Check the migration CPU and select which resources transfer (per-resource before/after CPU type is shown, and individual resources can be excluded).
4. Execute: the tool produces a migrated project ready to download, without manually re-entering system definitions or resource settings.

Applications

• Printing and web-handling machinery: SPH3300 over the SX bus drives multiple servo axes and position sensors along a print/laminate line, with analog signal feedback for tension or registration control.
• Equipment monitoring systems: SPH3300 and SPH2200 report into an operation-room HMI over Ethernet while separately managing plant equipment (servo systems, inverters, UPSs, motors, distribution panels, ultrasonic flowmeters, differential pressure/pressure transmitters) via SX bus or T-link.
• High-speed motion applications: packaging lines (PTP positioning), converting/cutting operations (2-axis linear interpolation), and flying shear / rotary cutting (main-axis speed control with interval synchronization).
• Retrofits of SPH2000, SPH3000(D), and SPH300 installations: the model transition function and documented replacement mapping make SPH2200/SPH3300 the direct upgrade path without a system redesign.
