The Siemens 6ES7155-6AU02-0BN0 is an interface module (IM 155-6 PN ST) designed for the SIMATIC ET 200SP distributed I/O system. It provides a PROFINET interface, supports up to 32 ET 200SP I/O modules and up to 16 ET 200AL modules, and enables “multi-hot swap” (insertion/removal during operation). It is optimized for high-performance automation environments and offers flexible connectivity via selectable BusAdapters.
This interface module is ideal for system integrators, machine builders and automation engineers deploying distributed I/O stations in industrial automation, manufacturing plants and control cabinets. It is especially suited for applications requiring flexible field cabling, high module count per station, hot-swap capability, and integration into PROFINET networks with diagnostics and redundancy support.
