Siemens 6ES7155-6AU00-0DN0 Interface Module

Siemens 6ES7155-6AU00-0DN0: SIMATIC ET 200SP IM 155-6PN High Feature Interface Module

The Siemens 6ES7155-6AU00-0DN0 (IM 155-6PN High Feature) is a high-performance PROFINET interface module designed for the SIMATIC ET 200SP distributed I/O system. Built for complex, high-speed industrial automation environments, this module bridges communication between central controllers (such as S7-1500 or S7-300 PLCs) and up to 64 local ET 200SP I/O modules over a PROFINET IO network.

Equipped with Isochronous Real-Time (IRT) communication capabilities and extensive system diagnostics, the IM 155-6PN HF guarantees precise synchronization, minimal response times, and maximum continuous uptime for modern manufacturing systems.

Key Features and Industrial Benefits

High-Speed Synchronization & IRT

Designed for demanding motion control and precise positioning tasks, the high-feature interface module supports IRT communication with ultra-low jitter, delivering dependable deterministic performance across your automation cell.

Flexible Media Redundancy (MRP)

Maintain continuous operation even during cable failure. With Media Redundancy Protocol (MRP) support, the module can participate in ring topologies, automatically switching data routes in milliseconds to prevent downtime.

Modular BusAdapter System

Adapt to any network cabling layout without changing the core interface unit. Choose between standard RJ45 connections, FastConnect (FC) direct termination, or fiber-optic connections by pairing the module with the appropriate Siemens BusAdapter.

Hot Swapping & Simple Maintenance

Reduce mean time to repair (MTTR). The ET 200SP system allows for multi-hot-swapping of individual I/O modules while the station remains under power and operational.

Applications

• Advanced PLC automation systems (Siemens S7-1200, S7-1500, PCS 7)

• High-speed packaging, assembly, and bottling lines

• Automotive manufacturing plants requiring fast tool-change functionality

• Process automation requiring redundant ring network topologies
