Overview

SIEMENS SIMATIC BUS LINKS

6ES7158-3AD01-0XA0 SIMATIC PN/PN Coupler

Connect two independently engineered PROFINET IO networks and exchange cyclic I/O data through an electrically separated coupling interface.

At a Glance

Brand	Siemens
Model	6ES7158-3AD01-0XA0
Product Type	Industrial network coupler
Core Function	Exchange process data between independent networks
Application	PROFINET IO subnet coupling

Separate subnet engineering

Each side is configured as an IO device in its own PROFINET subnet.

Integrated network ports

Two RJ45 ports on each side provide local switch connections.

Cyclic and acyclic exchange

Process data and data records support communication across the subnet boundary.

Product Overview

6ES7158-3AD01-0XA0 couples two PROFINET IO networks without combining their controller projects into one network configuration. Each side exchanges data with its assigned IO controller, allowing production sections to coordinate through defined transfer areas.

Firmware V3.0 supports a combined cyclic input/output data volume of up to 1024 bytes, data record transfer, shared device operation and MRP media redundancy.

Ordering focus: Match the transfer modules on both subnet sides and maintain identical input/output lengths for the paired data areas.

Key Functions

Exchange data across a controlled boundary

Two independent PROFINET IO subnets exchange configured cyclic data through the coupler rather than through a common controller program.

Integrate into line and ring structures

Integrated two-port switches support network wiring on both sides, while MRP provides media redundancy with the appropriate network configuration.

Transfer larger records on demand

Acyclic data record transfer handles records up to 8192 bytes in addition to the configured cyclic I/O exchange.

Frequently Asked Questions

Can 6ES7158-3AD01-0XA0 link two separately configured production lines?

Yes, each side operates as an IO device in an independent PROFINET IO subnet and exchanges the configured data with the other side.

Does 6ES7158-3AD01-0XA0 support Integrated network ports for mobile equipment?

Firmware V3.0 allows a combined total of 1024 bytes of cyclic input and output data with a selectable division.

How should I match the transfer areas when configuring 6ES7158-3AD01-0XA0?

Configure corresponding modules on both sides so that the input length of one side matches the output length of the other side.

Can I transfer recipes larger than the cyclic area with 6ES7158-3AD01-0XA0?

Acyclic data record transfer supports records of up to 8192 bytes.

Does 6ES7158-3AD01-0XA0 need an external switch for a local line connection?

Each subnet side has an integrated two-port switch for connecting the coupler within a line topology.

Can I include 6ES7158-3AD01-0XA0 in an MRP network?

Yes, firmware V3.0 supports MRP media redundancy when the network is configured accordingly.

What DC supply range should I provide for 6ES7158-3AD01-0XA0?

Provide a nominal 24 V DC supply within the permitted range of 20.4 to 28.8 V DC.

Compatibility & Ordering Notes

Before ordering 6ES7158-3AD01-0XA0: Plan both subnet configurations, the required cyclic data division and any data record transfer before selecting the controller-side modules.

Compatibility Checklist for 6ES7158-3AD01-0XA0

• Pair the input and output transfer modules across the two subnet configurations.
• Use the firmware V3.0 capabilities only with a matching device configuration.
• Allocate the four RJ45 connections to the correct X1 and X2 subnet sides.
• Provide the required 24 V DC supplies and configure supply monitoring for the installation.
