More Information

Overview Manuals Network Pairing Data Direction Address Setup State Indication

Features:

  • Two independent PROFIBUS DP slave interfaces form a controlled data boundary between separate master systems.
  • Cross-mapped input and output areas define the information exchanged in each direction.
  • Redundant power terminals and side-specific diagnostics support continuous supervision of the coupler.
Siemens 6ES7158-0AD01-0XA0 connects automation systems through mapped process data rather than electrically extending either PROFIBUS cable.

Each network commissions its own side of the coupler, allowing bus addresses and communication rates to remain local to that master system.

The separation of network states makes the side-specific LEDs useful when identifying whether a problem originates on network 1 or network 2.
The Siemens 6ES7158-0AD01-0XA0 SIMATIC DP DP/DP Coupler may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Keeping the two PROFIBUS systems independent

  • First DP Side: Network 1 addresses one slave interface from its own PROFIBUS master.
  • Second DP Side: Network 2 treats the opposite interface as a separate DP slave.
  • No Shared Segment: The coupler does not join the physical PROFIBUS cables into one bus.
  • Electrical Boundary: Galvanic separation is maintained between the two communication sides.

How values cross the coupler boundary

  • From Network 1: Outputs written by the first master are presented as inputs to the second master.
  • From Network 2: Outputs from the second master appear in the input area of the first master.
  • Defined Lengths: The configured data areas determine how many bytes move in each direction.
  • Consistency: Consistent-data settings keep related bytes together during the transfer.

Commissioning each slave interface

  • Independent Addresses: Each DP side receives the station address required by its local network.
  • Separate Projects: The coupler can be represented in the hardware configuration of both automation systems.
  • Matching Exchange: The input and output lengths on the two sides must describe the same cross-coupled data path.
  • Bus Parameters: Each side follows the baud rate and timing of the PROFIBUS network to which it is connected.

Locating a fault on the correct side

  • Side 1 LEDs: The first indicator group reports the operating and bus state of network 1.
  • Side 2 LEDs: A separate group provides the corresponding information for network 2.
  • Power Check: Supply indication confirms that the coupler electronics are energized.
  • Diagnostic Scope: A bus fault on one side can be investigated without treating the opposite network as the same segment.
Description
Siemens 6ES7158-0AD01-0XA0 is a SIMATIC DP DP/DP Coupler that transfers configured process data between two PROFIBUS DP networks. Each side appears as a DP slave to its own master, so the networks remain separate while exchanging a defined I/O image.

The internal mapping of 6ES7158-0AD01-0XA0 reverses direction across the boundary: output data written on one network becomes input data on the opposite network. The two master systems therefore exchange selected values without sharing a common PROFIBUS segment.

Both sides of 6ES7158-0AD01-0XA0 are configured for their respective bus addresses, data lengths, and consistency requirements. Because each interface operates independently, the connected DP networks can use their own communication settings within the coupler limits.

Separate indicators on 6ES7158-0AD01-0XA0 show the operating and bus condition of each interface. Redundant 24 V DC feed terminals support the device power path, while galvanic separation preserves the electrical boundary between the two PROFIBUS systems.

Technical notes
Siemens 6ES7158-0AD01-0XA0 is a data coupler, not a transparent PROFIBUS repeater. Each network configures the device as its own DP slave.
