Why Engineers Specify This Model
- High-Speed Execution: 0.065 µs per basic instruction enables tight scan-time control for demanding motion and process applications.
- Generous I/O Density: 80 onboard I/O points reduce panel footprint and wiring complexity versus multi-unit configurations.
- Relay Output Versatility: Dry-contact relay outputs switch AC and DC loads without external interface relays, simplifying BOM and reducing failure points.
- Scalable Architecture: Expand to 256 I/O points and add analog, positioning, or fieldbus modules as application requirements grow.
- Wide Ecosystem: Compatible with GX Works2/GX Works3 programming software, GOT HMI series, and the full MELSEC FX3U expansion library.
- Proven Reliability: MTBF exceeds 100,000 hours under rated conditions; widely deployed in Tier-1 automotive and electronics manufacturing.

Application-Specific FAQ
Q: What is the difference between FX3U-80MR/ES and FX3U-80MR/ES-A?
A: The FX3U-80MR/ES-A is the updated revision of the FX3U-80MR/ES. Both share identical electrical specifications and are fully interchangeable. The “/ES-A” suffix denotes a minor hardware revision with no functional difference for end users.
Q: Can the FX3U-80MR/ES control servo drives directly?
A: The base unit supports high-speed pulse output (up to 100 kHz on Y0/Y1/Y2) for open-loop stepper control. For closed-loop servo control, add the FX3U-20SSC-H SSCNET III positioning module.
Q: Is this PLC compatible with GX Works3?
A: The FX3U series is fully supported in GX Works2. GX Works3 supports FX3U via a compatibility mode. For new projects, Mitsubishi recommends GX Works2 for FX3U programming.
Q: What communication protocols does the FX3U-80MR/ES support?
A: Natively supports Mitsubishi’s proprietary protocol via RS-422. With optional modules, it supports Modbus RTU/ASCII (FX3U-485ADP-MB), PROFIBUS-DP (FX3U-64DP-M), CC-Link (FX3U-16CCL-M), and Ethernet/IP (FX3U-ENET-ADP).
Q: What is the maximum number of expansion modules?
A: Up to 8 special function modules and enough extension units/blocks to reach 256 total I/O points can be connected to the right side of the FX3U-80MR/ES base unit.
Q: Does this unit support data logging or recipe management?
A: Yes. With the FX3U-FLROM-64L memory cassette and appropriate programming, the FX3U supports data logging to internal registers. For advanced recipe management, integration with a GOT HMI or SCADA system is recommended.
