6ES7155-6AU01-0BN0

Product information

The 6ES7155-6AU01-0BN0 is a Siemens SIMATIC ET 200SP PROFINET interface module, IM 155-6 PN ST. It is the head module of an ET 200SP distributed I/O station: it connects the station to PROFINET and manages up to 32 I/O modules plus up to 16 ET 200AL modules. The article number includes the server module (6ES7193-6PA00-0AA0) that terminates the station.

Because the ET 200SP station is built up from the interface module and whatever I/O modules the application needs, this part is the one that determines how the remote station communicates — the I/O configuration around it can be adapted to the machine without changing the head module.

Understanding the ET 200SP naming

The interface module family is supplied in several feature levels, and the abbreviation in the product name identifies which one:

• PN ST — PROFINET standard, as described here
• PN HF — PROFINET high feature, with additional functions
• DP — PROFIBUS instead of PROFINET

Because the choice affects redundancy, module count and supported functions, replacement should be matched on the complete ordering code rather than the ET 200SP designation alone.

Typical applications

• Distributed I/O stations close to the machine, reducing wiring runs back to the main cabinet
• Modular machine concepts where the I/O complement changes between variants of the same machine
• Installations requiring single hot swapping, so a module can be exchanged without stopping the station
• Plants already standardised on SIMATIC ET 200SP as the remote I/O platform

Application examples describe typical uses of this product type. Suitability for your own installation must be confirmed against your engineering documentation.

Frequently asked questions

Is the server module included?
The article number 6ES7155-6AU01-0BN0 includes the server module 6ES7193-6PA00-0AA0 as supplied by Siemens. Confirm the scope of delivery for the specific unit offered.

How many modules can the station carry?
Up to 32 I/O modules, plus up to 16 ET 200AL modules.

What does hot swap support mean here?
Single hot swapping is supported, allowing one module to be replaced while the station remains in operation, subject to the station configuration.

What is the difference to IM 155-6 PN HF?
The HF version offers additional functions beyond the standard version. Match the complete ordering code when replacing an existing head module.

Can this module be used with a PROFIBUS network?
No. This is the PROFINET variant. A DP interface module is a different article number.

What is the price and lead time?
Confirmed individually against current availability for the specific revision and quantity.
