More Information

Overview Manuals Protocol Functions Interface Selection CS7 Configuration Product Applications

Features:

  • SS4 serial resource: The plug-in module adds one configured serial communication channel to a CS7.
  • Multiple protocol tasks: DUST1, DUST2, DUST3 and USS functions are supported in the SIMADYN D environment.
  • Scalable host arrangement: A CS7 can carry up to three SS4 plug-ins for separate serial links.
Host relationship: The SS4 depends on the CS7 submodule for mechanical mounting, interface selection and system integration.

Configuration role: HWConfig assigns the module and the communication function used by the station.

Connection planning: Software protocol choice and physical interface hardware are separate decisions that must agree with the installed cable.

Apter Power supports Siemens 6DD1688-0AD0 SS4 communication module sourcing with quotations, technical documentation and configuration review.

  • DUST1 support: The SS4 can be assigned to a DUST1 communication task.
  • DUST2 support: DUST2 is available as a distinct configured function.
  • DUST3 support: DUST3 is also supported within the SIMADYN D communication environment.
  • USS master: The module can run the USS master function at up to 187.5 kbit/s.
  • Standard interface: RS232 is the module’s standard electrical connection.
  • Optional interfaces: Other physical standards depend on the appropriate CS7 interface option.
  • Bus matching: An RS485 USS link therefore requires the related interface hardware as well as the SS4 configuration.
  • Cable decision: Connector appearance alone is not enough to identify the installed electrical standard.
  • Plug-in location: The SS4 installs on the CS7 communication submodule.
  • Module capacity: One CS7 accepts up to three SS4 plug-ins.
  • Engineering tool: The channel is assigned in HWConfig.
  • Project identity: The saved protocol task and interface option form part of the replacement record.
  • SIMADYN D serial links: The module adds configured serial communication to a CS7-equipped station.
  • Drive communication: USS master operation supports documented serial drive links.
  • Legacy data exchange: DUST tasks provide communication functions used in installed SIMADYN D applications.
  • Communication spares: The exact SS4 order number supports restoration of an existing CS7 channel.
Description
Serial data exchange for a SIMADYN D station is the role of the Siemens 6DD1688-0AD0 SS4 plug-in module. It mounts on the CS7 communication submodule and provides the hardware resource used by DUST and USS communication functions within that architecture.

The standard physical connection on 6DD1688-0AD0 is RS232. Other electrical interfaces, including RS485 arrangements used for USS, depend on the appropriate interface option, so the order number of the plug-in board alone does not define the complete field connection.

A project engineer configures the 6DD1688-0AD0 in HWConfig and selects the communication task required by the station. Up to three SS4 modules can be used on one CS7, allowing several serial links while keeping channel assignments and interface hardware explicit.

Technical notes
The standard port provided by 6DD1688-0AD0 is RS232; RS485 or other electrical arrangements require the corresponding interface option on the CS7 communication path. This distinction protects a retrofit from a connector-level mismatch even when the configured DUST or USS software function appears correct.

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.
Can a service engineer install 6DD1688-0AD0 directly in any SIMADYN D rack slot?
The SS4 is a plug-in module for the CS7 communication submodule, not a general rack card. The installed station therefore needs the correct CS7 host and an available plug-in position before this order number is selected.
How many independent SS4 links can one CS7 host with 6DD1688-0AD0?
Siemens allows up to three SS4 modules on a CS7. The practical link count still depends on the selected communication tasks and interface options, so the station layout should reserve a defined module position for each channel.
Can 6DD1688-0AD0 be used for a USS master connection?
Yes, the SS4 supports a USS master function up to 187.5 kbit/s. The physical interface must still suit the bus wiring, which may require the appropriate RS485 interface option rather than relying on the module’s standard RS232 connection.
Which configuration record is needed when replacing 6DD1688-0AD0?
Retain the HWConfig assignment together with the selected DUST or USS task and the interface option used on the CS7. Those records determine how the spare participates in the station and prevent a visually identical plug-in from being commissioned with the wrong link role.
Does 6DD1688-0AD0 support the same wiring for DUST1, DUST2 and DUST3?
The module supports those communication functions, but the name of the software task does not by itself define the electrical interface or cable. The configured function and installed interface hardware should be considered together when a link is restored.
What should procurement include when requesting 6DD1688-0AD0 for an installed CS7?
Use the full Siemens catalog number, SS4 designation and CS7 host context. Adding the required protocol task and physical interface from the site record helps suppliers quote the correct module path without implying that every SS4 arrangement is wired alike.
