JANCD-FC510
Description
1. General Description
2. Basic Specifications
Applicable system: YASNAC I80 / I80M (requires FC500 PLC board)
Backplane: JANCD-FC001 (1 full slot, adjacent to FC500)
Board size: Full-length (≈267 × 140 mm, matches FC500/FC4xx)
Power supply: DC 24V ±10%, approx. 0.8 A (low power)
Operating temperature: 0 to +45°C
Storage temperature: −20 to +60°C
3. Core Expansion Functions (vs. Base FC500)
A. Memory Expansion (Key Upgrade)
| Memory Type | FC500 (Base) | FC500 + FC510 (Expanded) |
|---|---|---|
| PLC Load Memory | 8 MB | 32 MB (4× expansion) |
| PLC Work Memory | 8 MB | 32 MB (4× expansion) |
| Retentive Bit Memory | 16 KB | 64 KB (4× expansion) |
| Max Ladder Logic Program Size | 64 KB/block | 256 KB/block |
B. I/O Processing Enhancement
Increases I/O scan speed from ≤0.8 ms to ≤0.2 ms (critical for high-speed safety interlocks)
Supports additional 128 I/O points (total system I/O up to 448 points with FC440)
Reduces PLC-CNC communication latency by 30% (for 5–6 axis motion synchronization)
C. Communication Interfaces
CN51: Expansion bus (dedicated link to FC500, high-speed data exchange)
CN21: Auxiliary I/O bus (for high-speed I/O boards like FC430/FC440)
LEDs: Power, expansion bus status, memory access, fault indicators
4. System Compatibility & Combinations
Mandatory Pairing
PLC core board: JANCD-FC500 (FC510 is an expansion, not a replacement)
CPU board: JANCD-FC250 (standard) or FC251 (high-grade)
Backplane: JANCD-FC001 (2 full slots: 1 for FC500, 1 for FC510)
Recommended Configurations
Standard expanded setup: FC250 + FC500 + FC510 + FC400 (32IN/32OUT)
High-density expanded setup: FC251 + FC500 + FC510 + FC430 (128IN/128OUT)
Max I/O expanded setup: FC251 + FC500 + FC510 + FC440 (160IN/160OUT)
Limitations
1 board per I80 system maximum (only one expansion slot for FC510)
Cannot replace FC500 – FC510 is strictly an expansion
Occupies 1 full slot on FC001 (must reserve adjacent slot to FC500)
5. FC510 vs. FC500 vs. FC4xx
| Item | FC510 (Expansion) | FC500 (PLC Core) | FC4xx (I/O Boards) |
|---|---|---|---|
| Role | Memory/I/O expansion | PLC logic execution | Physical I/O (sensors/actuators) |
| Memory | 32 MB load/work | 8 MB load/work | No PLC memory |
| I/O points | +128 points | Base 320 points | 32–160 IN/OUT |
| Dependency | Requires FC500 | Works with FC250/FC251 | Controlled by FC500+FC510 |
| Slot usage | 1 full slot | 1 full slot | 1 full/half slot |
6. Common Faults & Alarms
A.510 Expansion bus error: CN51 loose, FC500 communication failure, bus chip fault
Memory mismatch: FC510 not detected by FC500, incompatible firmware revision
I/O scan timeout: Excessive I/O points without FC510, FC4xx board overload
All LEDs off: 24V supply missing, internal fuse blown, backplane contact issue
Retentive data loss: Faulty FC510 memory chip, insufficient backup power
7. Applications
5-axis/6-axis high-complexity machining centers (large ladder logic programs, 100+ I/O points)
Multi-station transfer lines (high-speed synchronized I/O, large data logging requirements)
Fully automated production cells (machine + robotics + inspection + material handling integration)
Legacy I80 system upgrades (memory expansion without full CNC replacement for large machines)
High-end multi-spindle turn-mill centers (complex sequence control for dual spindles/B/C axes)
