Siemens 6ES7155-6BA01-0CN0 SIMATIC ET 200SP IM 155-6 DP HF PROFIBUS Remote I/O Interface Module

Siemens 6ES7155-6BA01-0CN0 is a SIMATIC ET 200SP interface module, product type designation IM 155-6 DP HF, that connects an ET 200SP I/O station to a PROFIBUS DP master. It supports up to 32 ET 200SP modules plus 16 ET 200AL modules, multi hot swapping, PROFIsafe, and a 24 V DC supply with reverse-polarity and short-circuit protection.

Technical Specifications

Selection Notes

The bundle configuration, which includes the server module and PROFIBUS plug, is intended for greenfield ET 200SP stations that need a complete PROFIBUS DP hookup out of the box rather than assembling the interface module and accessories separately. Multi-hot swapping supports replacing more than one I/O module at a time during operation, which matters for maintenance windows on stations with 32 modules where swapping modules one at a time would extend downtime. This SKU is scheduled for phase-out per Siemens SIOS 109989704, a factor to weigh for installations planning long-term spare-parts availability.

Applications

Distributed I/O for PROFIBUS DP-based plants, ET 200SP stations needing module replacement without a full station shutdown, and migration projects extending existing PROFIBUS installations with ET 200SP and ET 200AL I/O.
