Siemens 6ES7460-3AA00-0AB0: Remote Rack Transmitter Interface Module

Extend your S7-400 system beyond the central controller rack. The Siemens 6ES7460-3AA00-0AB0 (IM 460-3) is a transmitter interface module. It connects a central S7-400 rack to remote expansion racks over distances up to 102 meters using the K-bus. This allows you to distribute I/O modules closer to your machines and sensors.

Expert FAQs for System Architects

• What is the primary purpose of this module?
  Its main job is to act as the "launch point" in the central rack, extending the PLC's backplane (specifically the K-bus) over a cable to one or more remote racks filled with I/O modules.
• What is the difference between K-bus and P-bus in S7-400?
  The K-bus (communication bus) is used for transferring parameter data and for I/O modules that require intelligent communication. The IM 460-3 extends this K-bus, unlike other interface modules that extend only the I/O bus (P-bus).
• Can I connect multiple remote racks to one IM 460-3?
  Typically, one transmitter module connects to one receiver module in one expansion rack. For multiple remote racks, you would use multiple IM 460/461 pairs or other interface types that support branching.
• Why is it marked as "End of Production Lifecycle"?
  This indicates Siemens has discontinued manufacturing this specific variant. It is available for existing system repairs or specific legacy projects but is not recommended for new designs.
• What cables are required for the 102m connection?
  You need specialized, shielded connection cables designed for the S7-400 remote rack system (e.g., 6ES7 968-...). Standard Ethernet or Profibus cables are not suitable for this purpose.
