More Information

Overview Manuals GDM Role Fiber Channels LED States Rack Power

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.
Description
Siemens 6DD1660-0BG0 is the SIMATIC TDC CP52IO communication module that connects processor racks to GlobalDataMemory so CPU modules can exchange data through the central GDM structure.

Inside a GDM rack, 6DD1660-0BG0 occupies one slot beside the CP52M0 memory module, and each fitted CP52IO board extends the optical paths used to couple additional SIMATIC TDC racks.

Four Duplex SC channels on 6DD1660-0BG0 move data at 640 Mbit/s with 8B/10B coding and CRC checking; paired transmit and receive LEDs show activity for each optical interface.

The rack supplies 6DD1660-0BG0 from its 5 V and 3.3 V rails, while the module's 18 W typical power loss requires forced-air cooling in the installed frame.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can 6DD1660-0BG0 be separated from the CP52M0 memory board?
The 6DD1660-0BG0 is the CP52IO optical interface module; the CP52M0 is the separate central memory module in the GDM rack.
Which connection pattern belongs to 6DD1660-0BG0?
Four Duplex SC interfaces labeled X1 through X4 belong to 6DD1660-0BG0 and carry the GDM optical links.
Why does 6DD1660-0BG0 have eight front LEDs for four interfaces?
Each optical channel on 6DD1660-0BG0 has separate transmit and receive indication, producing four green and four yellow LEDs.
What rack resources must be reserved for 6DD1660-0BG0?
Reserve one SIMATIC TDC rack slot and forced-air cooling for 6DD1660-0BG0 because its typical power loss is 18 W.
Does 6DD1660-0BG0 use ordinary serial coding on its fiber links?
No. The optical links of 6DD1660-0BG0 operate at 640 Mbit/s with 8B/10B coding and CRC telegram checking.
