YOKOGAWA F3XP01-0H – High-Speed Counter Module | FA-M3 Series PLC
Engineering Background: The YOKOGAWA FA-M3 series is a high-performance modular PLC platform widely deployed in process industries, semiconductor manufacturing, and precision motion control. The FA-M3 architecture supports distributed I/O, high-speed data acquisition, and deterministic real-time control — making it a benchmark platform for demanding industrial automation projects.
Product Positioning: The F3XP01-0H is a dedicated high-speed counter module for the FA-M3 rack system. Designed for procurement engineers who require precise pulse counting, encoder feedback, and frequency measurement in high-throughput production environments. It eliminates the need for external counter hardware by integrating counting logic directly into the PLC backplane, reducing wiring complexity and improving signal integrity.

Engineering Advantages
- 200 kHz per channel — handles high-resolution encoders and fast pulse trains without external hardware.
- 32-bit counter depth — no rollover issues in long-run production without software intervention.
- Photocoupler isolation — protects the FA-M3 CPU from field-side noise and ground loops.
- Preset comparison output — hardware-level trigger reduces CPU scan-cycle dependency for time-critical events.
- Multi-voltage input — compatible with 5 V TTL encoders, 12 V and 24 V industrial sensors without signal converters.
- Single-slot form factor — maximizes rack density in space-constrained control panels.
- Backplane power only — no external 24 V module power supply required, simplifying panel design.
System Architecture & Signal Flow
The F3XP01-0H plugs directly into any slot of a FA-M3 base unit (F3BU series). Pulse signals from encoders or sensors enter via the front terminal connector, pass through photocoupler isolation, and are processed by the module’s onboard counter ASIC. Count values are written to the FA-M3 shared memory map and are accessible by the CPU module (F3SP series) within each scan cycle. The comparison register triggers a dedicated DO output independently of the CPU scan, ensuring sub-millisecond response for preset events.
Typical wiring path: Encoder / Pulse Sensor → F3XP01-0H Terminal Block → Photocoupler → Counter ASIC → FA-M3 Backplane Bus → CPU (F3SP□□) → HMI / SCADA

Technical FAQ
Q: Can the F3XP01-0H accept differential (RS-422) encoder signals?
A: The standard F3XP01-0H accepts single-ended (open collector / voltage) inputs. For differential RS-422 encoders, an external line receiver or signal converter is required before the module input terminals.
Q: Is the F3XP01-0H compatible with the FA-M3R (redundant) system?
A: Yes. The module occupies a standard I/O slot and is compatible with FA-M3R redundant CPU configurations. Counter data is accessible from both primary and standby CPUs via the shared memory architecture.
Q: What is the maximum cable length for pulse input signals?
A: YOKOGAWA recommends shielded twisted-pair cable up to 100 m for 24 V input signals at frequencies below 10 kHz. For 200 kHz operation, cable length should be kept under 10 m to maintain signal integrity.
Q: Can I use the F3XP01-0H for frequency measurement (not just counting)?
A: Yes. The module supports frequency measurement mode by reading the count value over a fixed gate time interval via the CPU ladder program. No additional hardware is required.
Q: What is the difference between F3XP01-0H and F3XP02-0H?
A: The F3XP01-0H provides 4 counter channels. The F3XP02-0H provides 8 channels in the same single-slot form factor, suitable for applications requiring more simultaneous encoder inputs.
