      Information

      Overview Manuals Common Applications Product Precautions
      When an engineering PC is connected to a legacy operator panel, Siemens 6ES5734-1BD20 provides the documented physical conversion path and must be matched to the panel variant before transfer work.
      • 3.2 m cable length
      • Integrated RS232/TTY converter
      • 25-pin PC RS232 side
      • Legacy operator-panel service

      The controlled engineering path is Engineering PC serial port → 25-pin RS232 connection → Integrated RS232/TTY conversion → Supported operator panel; preserve the approved system record and verify the intended final response before release.

      Important Notice: Confirm the target operator-panel variant and required serial settings before connecting the converter cable.

      Important Notice: The official Siemens cable matrix lists the exact 6ES5734-1BD20 converter cable and supported service path; the ApterPower guide provides a separate exact-model field sequence for preparation, connection checks, functional proving and acceptance.

      Operator-panel configuration
      Serial project transfer to a supported legacy panel.
      Service connection
      Temporary engineering link during controlled maintenance.
      Interface conversion
      Translate PC RS232 signaling to the required TTY connection.
      Legacy spare control
      Keep the exact converter cable with the documented panel service kit.
      Apply these exact-model controls to Siemens 6ES5734-1BD20 before isolation, replacement, reconnection, energization and final release.
      1
      Confirm the target panel and variant in the Siemens cable matrix.
      2
      Use the complete 6ES5734-1BD20 order number when selecting the cable.
      3
      Inspect connector pins, shells and strain relief before connection.
      4
      Do not substitute a passive serial cable for the integrated converter assembly.
      5
      De-energize or place the panel in the documented service state before connecting.
      6
      Secure the 3.2 m cable to prevent pull load on either connector.
      7
      Use the panel-specific transfer settings and communication procedure.
      8
      After transfer, confirm the panel project and remove the service cable safely.
