The 6ES7155-6AU00-0BN0 is an IM 155-6 PN Standard interface module for a SIMATIC ET 200SP distributed I/O station. It links the station to PROFINET and manages communication between the controller and installed ET 200SP I/O modules.
PRIMARY ROLE
IM 155-6 PN Standard
This article is a spare-part version and includes the server module. Its station capacity, selected BusAdapter, I/O layout and controller engineering must match the installed ET 200SP node.
Product type
PROFINET interface module
Station family
SIMATIC ET 200SP
Maximum I/O modules
32 ET 200SP I/O modules
Included component
Server module
Network role
PROFINET IO device interface for the distributed station
The PROFINET controller exchanges cyclic I/O data with the IM 155-6 PN Standard. A compatible BusAdapter provides the physical network connection, BaseUnits carry the electronic I/O modules, and the server module terminates the station assembly. The exact article revision and installed engineering release must be checked before replacement.

PURCHASE QUESTIONS
FAQ for 6ES7155-6AU00-0BN0
Can 6ES7155-6AU00-0BN0 be replaced directly by 6ES7155-6AU02-0BN0?
Do not treat the successor as an automatic drop-in exchange. Confirm controller engineering, firmware, BusAdapter, configured modules, station limits and supported replacement procedure before shutdown.
What should be checked before ordering 6ES7155-6AU00-0BN0?
Record the full label, hardware and firmware versions, selected BusAdapter, number and order of I/O modules, server module condition and the controller project version.
Does 6ES7155-6AU00-0BN0 include the PROFINET connector?
The article includes the server module, while the station network connection depends on the selected ET 200SP BusAdapter. Verify the existing BusAdapter separately.
How should a 6ES7155-6AU00-0BN0 replacement be commissioned?
Preserve the controller project, reproduce the physical module order, inspect BaseUnit coding and wiring, restore the device name and verify diagnostics before enabling field outputs.
Why does the lifecycle state matter when buying 6ES7155-6AU00-0BN0?
This article has reached the end of its product lifecycle. Buyers should verify whether an exact spare is required or whether a controlled migration to the successor is acceptable.
