Siemens 6ES7158-3AD10-0XA0 SIMATIC PN/PN Coupler 2-Port IRT Remote I/O Interface Module

The Siemens 6ES7158-3AD10-0XA0 SIMATIC PN/PN Coupler is a remote I/O interface module that connects up to four PROFINET IO controllers per subnet, including subnet-to-subnet coupling, over two PROFINET ports fitted via SIMATIC BusAdapter. It supports IRT with Dynamic Frame Packing, PROFIsafe data exchange, and a 24 V DC supply rated 19.2-28.8 V with reverse-polarity protection.

Technical Specifications

Selection Notes

The 16 configurable coupling modules split 1 write / 3 read submodules each in non-isochronous mode, so plan the input/output record split before commissioning since that ratio is fixed. Switching to isochronous mode drops capacity to 3 coupling modules with 500 microsecond cycles, so choose non-isochronous operation when the full 16-module count is needed. The unit ships without a BusAdapter, so an RJ45, FC, or optical (LC/SCRJ) BusAdapter pair must be ordered separately to match the target port count and medium.

Applications

Use the 6ES7158-3AD10-0XA0 to exchange I/O, MSI/MSO, and data-record traffic between up to four PROFINET IO controllers on the same subnet or across two subnets without a shared master controller, such as linking a machine cell's local PLC to a plant-wide line controller while keeping each PROFINET domain separate. PROFIsafe pass-through carries safety data across that same boundary, and PROFINET system redundancy (S2) in non-isochronous mode keeps the coupling available if one controller connection drops.
