      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • Siemens 6DD1688-0AD0 links a configured SIMADYN D system to service equipment, printers, SIMATIC S5 or USS devices. Protocol selection and physical signaling must match the connected equipment.
      Product type: SS4 communication module
      Carrier: CS7 support module
      Maximum baud rate: 187.5 kbaud, configuration dependent
      The 6DD1688-0AD0 SS4 is installed in a CS7 support module, which accepts up to three communication modules. HWConfig defines the carrier, communication module and selected slot. Exchange with the CPU uses the 16 KB dual-port RAM on CS7, so carrier configuration is part of the communication arrangement.

      Supported protocol applications include DUST1 for configuring and operator PCs, DUST2 for a message printer and DUST3 for SIMATIC S5 AS 512 or CP 525 connections. With USS, SS4 acts as master for devices such as OP2 panels, VD1 displays and compatible converters. The maximum rate is 187.5 kbaud, subject to the protocol software and physical-interface hardware.

      The standard physical interface is RS-232. Optional SS1, SS2 and SS31 interface modules provide 20 mA current-loop, RS-232 with control signals and RS-485 arrangements respectively. Fit an optional module at X51 with pin-one orientation aligned. Connect the SS4 and CS7 front panels as specified, secure the signal connector and bond cable shielding over a broad surface at the cabinet entry.
      Controller platform reference: SIMADYN D SS4. Match the installed configuration before replacement.
      Technical downloads for 6DD1688-0AD0: an original Siemens reference excerpt and an Apter Power installation planning guide.
      SS4 functions depend on the selected protocol software and physical-interface module; CS7 is the required support module. The planning guide is prepared by Apter Power; apply the complete manufacturer instructions and the stated applicability boundaries.
      System and supply context: SS4 functions depend on the selected protocol software and physical-interface module; CS7 is the required support module. Accessories are included only when itemized in the quotation.

      Platform applications: The following applications describe SIMADYN D SS4 functions. Match the complete 6DD1688-0AD0 identity to the installed system before selecting a replacement.
      Prepare 6DD1688-0AD0 against the installed configuration and applicable Siemens instructions. Plan isolation and the resulting interruption of system operation before replacement.
      Isolate the system

      Place the connected process in a safe state and isolate the control supply before handling SS4 or its interface module.

      Match the protocol

      Verify DUST or USS configuration and the corresponding equipment; physical fit alone does not establish communication compatibility.

      Check the carrier

      Retain CS7 slot allocation and HWConfig settings when replacing the module.

      Orient the interface

      At X51, align the recess and pin-one marking of the optional interface with the socket.

      Bond and terminate

      Connect front-panel grounding, secure the connector and maintain shield bonding. Apply the specified termination at the ends of an RS-485 bus.

      Verify diagnostics

      Check the associated CS7 LEDs and a controlled data exchange before releasing the process.

      Technical notes

      Installation relationship: Supported protocol applications include DUST1 for configuring and operator PCs, DUST2 for a message printer and DUST3 for SIMATIC S5 AS 512 or CP 525 connections. With USS, SS4 acts as master for devices such as OP2 panels, VD1 displays and compatible converters. The maximum rate is 187.5 kbaud, subject to the protocol software and physical-interface hardware.

      Configuration: SS4 functions depend on the selected protocol software and physical-interface module; CS7 is the required support module.
