Mitsubishi MELSEC iQ-R vs iQ-F (FX5U): PLC Migration & CC-Link IE TSN Setup
Mitsubishi Electric's MELSEC controller architecture spans the modular flagship MELSEC iQ-R Series (high-speed synchronized processes) and the compact MELSEC iQ-F Series (FX5U / FX5UJ) replacing the legendary FX3U.
1. MELSEC iQ-R vs iQ-F (FX5U) Comparison

|---|---|---|
| Program Capacity | Up to 1200k steps | Up to 128k steps (FX5U) |
| LD Instruction Speed | Ultra-fast 0.98 ns | High-speed 34 ns |
| Motion Synchronization | Multi-CPU architecture (Up to 64 axes / CPU) | Embedded 4-axis 200 kHz pulse positioning |
| Network Protocol | CC-Link IE TSN (Gigabit Real-Time Bus) | CC-Link IE Field Basic / Ethernet / Modbus |

2. GX Works3 Project Migration from FX3U
When converting legacy FX3U ladder logic to FX5U in GX Works3:
- Ladder instructions (e.g.
PLSY,PWM,DMOV) are automatically converted to standardized Structured Text (ST) and Module FB blocks. - Hardware analog inputs (
0-10Von FX5U CPU) replace externalFX2N-2ADmodules, saving cabinet space.
