More Information

Overview Manuals Protocol Role CS7 Integration Configuration Product Applications

Features:

  • Protocol support: Handles PROFIBUS-FMS, PROFIBUS-DP, and MPI communication.
  • Host architecture: Installs on a configured Siemens CS7 support module.
  • CPU exchange: Uses the CS7 16 KB dual-port RAM for data transfer.
Protocol role and CS7 receptacle are project-specific selection details.

X5 provides the isolated RS485 PROFIBUS interface and optical-link-module supply.

The COMSS5 database and HWConfig record help preserve the intended network behavior.

For Siemens 6DD1688-0AE0 SIMADYN D SS5 Communication Module projects, Apter Power supports CS7 records, technical documents, sourcing review, and quotations.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • PROFIBUS-FMS: Supports the documented master communication function.
  • PROFIBUS-DP: Can operate as a configured master or slave with shared-input, SYNC, and FREEZE functions.
  • MPI: Provides the Siemens multipoint protocol path where configured.
  • Role control: Retain the configured protocol role with the module record before any network change.
  • Receptacle: The SS5 position is assigned together with its CS7 support module.
  • Module count: A maximum of three communication modules can be installed on one CS7.
  • CPU path: Data reaches processor modules through the CS7 dual-port RAM.
  • Position record: Keep the CS7 receptacle and adjacent-module layout with the HWConfig evidence.
  • HWConfig: Defines the CS7, SS5, and selected receptacle.
  • COMSS5: Provides the required communication database for SS5 operation.
  • Bus record: Protocol role, station addresses, and terminating arrangement should remain documented.
  • Legacy PROFIBUS: Connects SIMADYN D controls to documented FMS or DP networks.
  • Controller integration: Supports communication where a CS7 hosts the required SS5 position.
  • Maintenance projects: Relevant to retaining established bus roles and network configuration.
Description
Adding fieldbus communication to a SIMADYN D system, 6DD1688-0AE0 is the Siemens SS5 module inserted on a CS7 support module. Siemens documents PROFIBUS-FMS master operation, PROFIBUS-DP master or slave operation, and MPI support.

The CS7 hardware configuration defines the receptacle used by 6DD1688-0AE0, with up to three communication modules per support module. CPU data moves through the CS7’s 16 KB dual-port RAM, while X5 provides the isolated RS485 PROFIBUS interface and power for optical link modules.

Before service, the COMSS5 database and HWConfig assignment should be retained with the network records. Siemens lists the article at the end of its product lifecycle, and Apter Power can support 6DD1688-0AE0 quotations, documentation, and exact-position matching for legacy projects.

Technical notes
For 6DD1688-0AE0, retain the CS7 receptacle assignment, HWConfig record, COMSS5 database, PROFIBUS role, station addressing, and X5 bus connection. These records define how SS5 participates in the network. Apter Power can compare the exact module position and communication evidence before coordinating official documents, sourcing review, and an accurate quotation.

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.
A spare 6DD1688-0AE0 arrives configured as a DP slave, but the installed position is a master. What should be restored?
Restore the intended HWConfig and COMSS5 database, then verify the bus role, address, termination, and connected nodes before commissioning the spare.
Communication remains offline after replacing 6DD1688-0AE0. Which identity detail should be checked first?
Confirm the assigned CS7 receptacle and that the saved configuration addresses that same position. A correct module in the wrong logical position can remain unavailable.
Engineering wants to move 6DD1688-0AE0 to another CS7 receptacle. Is the physical move sufficient?
No. The HWConfig, communication database, bus cabling, addresses, and project record must follow an approved change so the processor uses the new position.
An optical link module is being added near 6DD1688-0AE0. What should be verified at X5?
Confirm the documented RS485 interface, optical-link-module supply arrangement, bus role, connector, termination, and network design before connecting the new path.
A CS7 already hosts several communication modules with 6DD1688-0AE0. What limits the next addition?
Siemens allows up to three communication modules, but receptacle assignment, power, configuration, protocol roles, and project topology still determine whether another position is appropriate.
Which records should accompany a quotation for 6DD1688-0AE0?
Provide the full label, CS7 receptacle, X5 photos, protocol and DP role, HWConfig and COMSS5 references, network addresses, quantity, condition, and destination.
