Siemens 6ES7155-6AU01-0BN0 SIMATIC ET 200SP Interface Module
6ES7155-6AU01-0BN0 is the Siemens IM 155-6 PN Standard PROFINET interface module for SIMATIC ET 200SP distributed I/O. It supports up to 32 ET 200SP I/O modules and up to 16 ET 200AL modules, with single hot swap. The official product scope includes server module 6ES7193-6PA00-0AA0.
The module uses a rated 24 V DC supply. Engineering and commissioning must confirm the applicable TIA Portal or STEP 7 version, firmware, GSDML file, BusAdapter and station configuration.
Siemens lists the product in PM400 phase-out status from 1 October 2024 and identifies 6ES7155-6AU02-0BN0 as the official successor. The successor adds multi hot swap, optional PN strain relief and PN security class 1. Compatibility must be checked before replacement. AMIKON can help source available spare units for installed systems.
Product: Siemens 6ES7155-6AU01-0BN0 SIMATIC ET 200SP interface module.
Designation: IM 155-6 PN Standard PROFINET interface module.
Station capacity: Maximum 32 ET 200SP I/O modules and 16 ET 200AL modules.
Included component: Server module 6ES7193-6PA00-0AA0.
Service support: AMIKON can help source available spare units for installed systems, subject to availability and configuration verification.
PROFINET interface: Connects a SIMATIC ET 200SP distributed I/O station to a PROFINET controller.
Expansion capacity: Supports up to 32 ET 200SP I/O modules and up to 16 ET 200AL modules.
Hot swap: Supports single hot swap for the applicable station configuration.
Supply: Rated for 24 V DC with a permissible range of 19.2 to 28.8 V DC.
Server module: Includes Siemens server module 6ES7193-6PA00-0AA0.
Distributed machine I/O: Used to connect decentralized sensors and actuators to a PROFINET automation system.
Production automation: Suitable for ET 200SP stations in manufacturing cells, assembly equipment and packaging machinery.
Process skids: Supports modular remote I/O stations where compact installation and service access are required.
System expansion: Supports mixed ET 200SP and ET 200AL station designs within the stated module limits.
Installed-base maintenance: Can be used as a verified spare for an existing station with the same article number and compatible hardware, firmware and project configuration.
Engineering software: Check STEP 7 in TIA Portal V14 or later and STEP 7 V5.5 SP4 or later for the applicable hardware status.
Firmware: Confirm the module hardware status and firmware version in the existing station before replacement or project download.
Device description: Confirm that the engineering system contains the matching Siemens hardware catalog entry or compatible GSDML file.
Station design: Verify the configured number and order of ET 200SP I/O modules and ET 200AL modules.
BusAdapter: Confirm the installed BusAdapter and PROFINET port arrangement because the standalone interface module and bundle article numbers have different scopes of supply.
Replacement check: Before migration to 6ES7155-6AU02-0BN0, verify project configuration, firmware, GSDML, hot-swap behavior, optional strain relief and PN security requirements.
Lifecycle status: Siemens lists 6ES7155-6AU01-0BN0 as PM400 with product phase-out announced.
Effective date: Product phase-out has applied since 1 October 2024.
Official successor: Siemens identifies 6ES7155-6AU02-0BN0 as the successor.
Successor differences: The newer module supports multi hot swap, optional PN strain relief and PN security class 1.
Migration requirement: The successor should not be treated as an automatic drop-in replacement. Verify the project, firmware, GSDML, BusAdapter and security requirements before conversion.
Spare sourcing: AMIKON can help source available spare units for installed systems when continued use of the original article number is required.
