The FX3U-64CCL is Mitsubishi Electric’s CC-Link Ver.2 intelligent device station module for the MELSEC FX3U compact PLC series, enabling any FX3U base unit to participate in a CC-Link network as an intelligent slave device — allowing a higher-level MELSEC-Q, MELSEC iQ-R, or any CC-Link master to read and write FX3U data via the CC-Link network, integrating the FX3U into distributed control hierarchies managed by a larger PLC system. As the intelligent device slave counterpart to the FX3U-16CCL-M master module, the FX3U-64CCL is the standard specification for FX3U subsystem controllers that must report production data, receive recipe setpoints, and exchange status information with a supervisory MELSEC-Q master without requiring Ethernet or serial communication infrastructure.

What Is the FX3U-64CCL?
The FX3U-64CCL is a MELSEC FX3U series special function module implementing the CC-Link Ver.2 intelligent device station protocol — the slave station specification that allows a FX3U controller to appear as a CC-Link intelligent device station on a CC-Link network managed by any CC-Link master. In this configuration, the CC-Link master (typically a MELSEC-Q with QJ61BT11N module, or a MELSEC iQ-R with RJ61BT11 module) manages the CC-Link cyclic data exchange, reading remote I/O data (RY outputs and RWw register data written by the master are received by the FX3U-64CCL and mapped to FX3U device memory) and reading the FX3U’s status data (RX inputs and RWr register data from the FX3U are transmitted to the master via the CC-Link cycle). The FX3U-64CCL supports CC-Link Ver.2 extended cyclic modes (×2, ×4, ×8), enabling up to 512 RX/RY remote I/O points and 128 RWr/RWw remote register words to be exchanged between the master and the FX3U in each network scan cycle — sufficient for comprehensive production data reporting and recipe management without supplementary communication channels.

Typical Industrial Applications
The FX3U-64CCL is deployed in hierarchical control architectures where a central MELSEC-Q or iQ-R system manages multiple FX3U subsystem controllers via CC-Link. In automotive assembly lines, a MELSEC-Q supervisory controller with a QJ61BT11N CC-Link master manages 20–30 FX3U station controllers — each FX3U equipped with a FX3U-64CCL — exchanging production counts, cycle time data, fault codes, and operation mode commands via the CC-Link network without requiring dedicated Ethernet drops to each station. The FX3U-64CCL’s auto-refresh function maps the CC-Link received data (RWw registers from master) to FX3U D register addresses automatically, allowing the FX3U ladder program to read recipe parameters from D registers as if they were locally set values rather than network-received data. In food and beverage packaging facilities, FX3U filling machine controllers with FX3U-64CCL modules report fill counts, weight averages, and reject reasons to a MELSEC-Q plant controller via CC-Link, enabling centralised production tracking without requiring individual Ethernet connectivity at each filling machine. Textile manufacturing uses the FX3U-64CCL to connect individual loom FX3U controllers to a production management MELSEC-Q system, reporting metre counts, end-break events, and pattern change commands via the CC-Link infrastructure already installed in the weaving shed for legacy MELSEC-A device stations.
Replacement & Upgrade Notes
The FX3U-64CCL is the direct replacement for the legacy FX2N-64CL-M (which provided CC-Link Ver.1 local station functionality) in retrofit projects migrating FX2N subsystem controllers to FX3U while retaining the existing CC-Link infrastructure. When replacing an FX2N-64CL-M with an FX3U-64CCL, note that the FX2N-64CL-M operated as a local station (a CC-Link station type with its own program and I/O resources) while the FX3U-64CCL operates as an intelligent device station (a simpler slave type with only remote I/O and remote register data exchange). If the original FX2N installation used CC-Link local station features (such as accessing the local station’s I/O from its own program independently), the FX3U-64CCL’s intelligent device station architecture may require adaptation of the control strategy — consult Mitsubishi’s CC-Link migration guide for FX2N-to-FX3U network architecture considerations. For new system designs using CC-Link, Mitsubishi recommends evaluating the FX5U iQ-F series for future-proof CC-Link IE Field Network compatibility — the FX5U provides built-in CC-Link IE Field master capability without requiring a separate module, while retaining backward compatibility with CC-Link Ver.2 via the FX5-CCL-MS add-on module for legacy slave device integration.
Frequently Asked Questions
Q: Can the FX3U-64CCL be used in the same FX3U system as the FX3U-16CCL-M master module?
A: No. A single FX3U system cannot simultaneously act as both a CC-Link master (FX3U-16CCL-M) and a CC-Link slave (FX3U-64CCL) — the two modules serve opposite roles on the CC-Link network and cannot coexist in the same FX3U base unit. A given FX3U system must be configured as either master or slave for a CC-Link network, not both simultaneously.
Q: How is the FX3U-64CCL station number and occupied station count configured?
A: The FX3U-64CCL station number (1–64) and occupied station count (1–4 stations) are configured via DIP switches on the module’s front panel. The station number must be set to a unique value that does not conflict with any other CC-Link station on the network. The occupied station count determines the number of CC-Link cyclic data points allocated — 1 occupied station provides 16 RX/RY + 4 RWr/RWw in Ver.1 mode; with Ver.2 ×8 extended cyclic and 4 occupied stations, up to 512 RX/RY + 128 RWr/RWw can be exchanged. The master station’s GX Works2 configuration must match the occupied station count set on the FX3U-64CCL module for the slave to initialise correctly.
Q: Can the FX3U-64CCL exchange data with a MELSEC iQ-R CC-Link master?
A: Yes. The FX3U-64CCL is a standard CC-Link Ver.2 intelligent device station and is compatible with any CC-Link master regardless of the master’s CPU platform — MELSEC-Q (QJ61BT11N), MELSEC iQ-R (RJ61BT11), or any CLPA-certified third-party CC-Link master. The master configures the FX3U-64CCL using Mitsubishi’s CSP (CC-Link Station Profile) file in the master’s engineering software, and the cyclic data exchange proceeds automatically once the network is configured and powered.
