Features:
- The CP52IO module connects SIMATIC TDC processor racks with the GlobalDataMemory system.
- Four Duplex SC interfaces transfer GDM data at 640 Mbit/s with CRC checking.
- Eight front LEDs separate transmit and receive activity for the four optical channels.
Siemens 6DD1660-0BG0 is the CP52IO member of the SIMATIC TDC GlobalDataMemory component group.
The module uses one rack slot and works as an optical interface board rather than the CP52M0 central memory board.
Its 20 mm front width fits the SIMATIC TDC rack format, while the specified power loss requires a rack fan.
The Siemens 6DD1660-0BG0 SIMATIC TDC CP52IO GDM Communication Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Position in GlobalDataMemory
- Central exchange: GDM permits CPU modules in networked racks to share data through central memory.
- Interface position: CP52IO boards occupy rack slots beside the CP52M0 memory module.
- Rack expansion: Each CP52IO provides the optical paths used to couple further racks.
- Order identity: The 0BG0 suffix belongs to the CP52IO interface module, not the CP52M0 memory board.
Four Optical Data Paths
- Connectors: X1 through X4 use Duplex SC fiber-optic connections.
- Channel rate: Each documented optical interface operates at 640 Mbit/s.
- Line coding: The data path uses 8B/10B coding.
- Error check: CRC verifies the transferred telegrams.
Transmit and Receive Indication
- LED pairs: Each of the four optical interfaces has one transmit and one receive indicator.
- Green indication: H1, H3, H5, and H7 show data transmission.
- Yellow indication: H2, H4, H6, and H8 show data reception.
- Channel tracing: The front sequence keeps send and receive states aligned with interfaces 1 through 4.
Slot, Rails, and Cooling
- Rack width: One slot accommodates the 20 mm wide module.
- 5 V requirement: At 25 °C, the documented typical draw is 3.0 A.
- Lower-voltage rail: The 3.3 V connection carries a documented typical draw of 0.8 A at 25 °C.
- Thermal load: Typical power loss is 18 W and operation requires a fan.
