Product Overview
| Parameter | Details |
|---|---|
| Part Number | 6DD1661-0AD0 |
| Product Name | SIMATIC TDC CS51 Communication Module |
| Application | High-speed, deterministic communication for SIMATIC TDC and SIMADYN D control systems in complex drive, motion, and process automation applications |
| Compatibility | - SIMATIC TDC (CPU55x, SM500, GDM) - SIMADYN D subsystems - TDC rack via backplane - Supports PROFIBUS DP, PROFINET, Drive-CLiQ, and peer-to-peer links |
| Function | Provides dual-port PROFIBUS DP master/slave, PROFINET IO controller, Drive-CLiQ interface, and high-speed peer-to-peer data exchange; enables isochronous real-time (IRT) communication with cycle times down to 31.25 µs |
Functional Specifications
| Parameter | Details |
|---|---|
| Communication Interfaces | - 2 _ PROFIBUS DP (RS485, 12 Mbps, master/slave) - 1 _ PROFINET IO (2-port switch, 100 Mbps, IRT) - 1 _ Drive-CLiQ (Siemens servo/motor interface) - 1 _ Ethernet (100 Mbps, diagnostics/web server) |
| PROFIBUS DP | - Up to 125 slaves per port - DP-V1/V2 acyclic services - Isochronous mode (sync with TDC cycle) |
| PROFINET IO | - IRT (Class C), RT support - Up to 128 IO devices - Shared Device, MRP, Media Redundancy |
| Drive-CLiQ | - Up to 8 nodes (drives, encoders, I/O) - 1 MHz sampling, topology-based auto-config |
| Peer-to-Peer (TDC-GDM) | - 64 KB cyclic data per link - 31.25 µs cycle (synchronous with TDC) |
| Synchronization | - IEEE 1588 PTP, DC-BUS sync, TDC global clock |
| Diagnostics | - Channel-level LED (LINK, ACT, ERR per port) - Web server (module status, topology, logs) - SNMP, LLDP, PROFINET diagnostics |
| Configuration | - TIA Portal V18+ (with TDC library) - SIMATIC TDC Engineering Tool - GSDML / GSD files |
| Firmware | Field-upgradable via PROFINET, USB, or TDC backplane |
