6ES7155-6AU02-0BN0 ET 200SP IM 155-6 PN ST Interface Module | Siemens

The Original New Siemens 6ES7155-6AU02-0BN0 is a PROFINET Standard interface module for the SIMATIC ET 200SP distributed I/O system, designed to connect up to 32 ET 200SP I/O modules and 16 ET 200AL modules to a PROFINET network. This second-generation ST variant introduces multi hot swapping, allowing multiple modules to be replaced during operation without stopping the station, significantly reducing downtime in continuous process and manufacturing environments. The module supports PROFINET IO with IRT (125 µs isochronous cycle, 1–4 ms), integrated 2-port switch via BusAdapter, and PN Security Class 1. The server module (6ES7193-6PA00-0AA0) is included in the scope of delivery.

Core Engineering Highlights:
PROFINET IO interface module (IM 155-6 PN ST, 2nd generation) | Max. 32 ET 200SP I/O modules + 16 ET 200AL modules | Multi hot swapping | PROFINET IRT (125 µs isochronous cycle) | Integrated 2-port switch (via BusAdapter) | PN Security Class 1 | 288 bytes address space per module / 1,440 bytes per station | 24 V DC (19.2–28.8 V DC) | 350 mA rated current / 450 mA max | 1.8 W power loss

Key Features:

• Original New Siemens 6ES7155-6AU02-0BN0 interface module (IM 155-6 PN ST)

• Supports up to 32 ET 200SP I/O modules and 16 ET 200AL modules per station

• Multi hot swapping — multiple modules can be replaced during operation without stopping the station (distinguishes this 6AU02 version from the 6AU01 single hot swap variant)

• PROFINET IO device with IRT support for isochronous applications (125 µs send clock, 1–4 ms)

• Integrated 2-port switch (switch integrated in the interface module; BusAdapter required for RJ45, FC, or M12 connection)

• Supports BusAdapter variants: BA 2x RJ45, BA 2x FC, BA 2x M12

• PN Security Class 1 for protected PROFINET communication

• Optional PN strain relief for mechanical cable strain relief

• 288 bytes address space per module (input and output respectively); 1,440 bytes per station

• I&M data I&M0 to I&M4 for identification and maintenance

• Supports PROFlenergy, shared device (up to 4 IO controllers), and priority startup

• Local coupling with 6 coupling modules (1 output + max. 5 inputs)

• Firmware version V6.4.0; FW update possible

• Server module 6ES7193-6PA00-0AA0 included in scope of delivery

Applications:

• Distributed I/O stations in PROFINET networks requiring high availability (multi hot swap)

• Process automation and manufacturing lines where module replacement must occur without stopping production

• Systems requiring isochronous motion control (IRT with 125 µs cycle)

• ET 200SP stations with a mix of standard I/O and ET 200AL modules in confined spaces

• Applications requiring PN Security Class 1 for network protection

• Factory automation and machine building with PROFINET-based control architectures

Technical Specifications:

System Compatibility:

• Part of the SIMATIC ET 200SP distributed I/O system.

• Connects to PROFINET IO controllers (SIMATIC S7-1200, S7-1500, S7-300/400, or third-party PROFINET masters).

• Requires a compatible BusAdapter (BA 2x RJ45, BA 2x FC, or BA 2x M12) for the physical PROFINET connection — BusAdapter sold separately.

• Supports ET 200SP I/O modules (max. 32) and ET 200AL modules (max. 16) per station.

• Configurable via TIA Portal V20 or STEP 7 V5.7 SP3 (or higher); GSDML V2.45 for third-party engineering systems.

• Server module (6ES7193-6PA00-0AA0) is included and required for station completion.
