      Information

      Overview Manuals Common Applications Product Precautions
      In a CS 275 network, Siemens 6DS1223-8AA depends on correct backplane switch selection, 1:1 cable continuity and the specified end connector for stable local-bus communication.
      • N-AS local-bus interface
      • CS 275 communication
      • 20 m local-bus connection
      • Documented end termination

      The controlled engineering path is AS or OS equipment → 6DS1223-8AA N-AS → Connection distribution → Redundant CS 275 local bus; preserve the approved system record and verify the intended final response before release.

      Important Notice: Confirm the 20 m bus limit, 0.2 V earth-potential limit, 1:1 cable order and final termination before startup.

      Siemens 6DS1223-8AA Official Technical Reference Excerpt (PDF)Siemens 6DS1223-8AA Installation & Commissioning Guide (PDF)

      Important Notice: The official Siemens manual documents the applicable TELEPERM M installation context; the ApterPower guide provides a separate exact-model field sequence for preparation, connection checks, functional proving and acceptance.

      Automation-system connection
      Link an AS to the CS 275 local bus.
      Operator-system connection
      Connect an OS through the documented local-bus architecture.
      Redundant bus service
      Support the standard redundant local-bus arrangement.
      N-AS replacement
      Preserve topology, cable order and switch state during maintenance.
      Apply these exact-model controls to Siemens 6DS1223-8AA before isolation, replacement, reconnection, energization and final release.
      1
      Record the full CS 275 topology and participant state before shutdown.
      2
      Match the complete 6DS1223-8AA identity and N-AS designation.
      3
      Keep the local-bus section within 20 m.
      4
      Measure and control earth-potential difference to no more than 0.2 V.
      5
      Set S11 and S12 to ON when the N-AS is installed.
      6
      Reconnect the cable 1:1 by conductor color and ring number.
      7
      Terminate the final open cable end with front connector 6DS9200-8AA.
      8
      Verify communication to every required participant after startup.

      Technical notes

      For the N-AS installation, control the 20 m local-bus section and the 0.2 V earth-potential limit. Restore the documented termination and prove the redundant communication path before handover.
