Siemens 6ES7155-6AA02-0BN0 SIMATIC ET 200SP IM 155-6 PN ST incl. BA 2xRJ45 Remote I/O Interface Module

The Siemens 6ES7155-6AA02-0BN0 is a SIMATIC ET 200SP PROFINET interface module (IM 155-6 PN ST) supplied as a bundle with a BA 2xRJ45 bus adapter and server module, supporting up to 32 ET 200SP I/O modules plus 16 ET 200AL modules per station. It provides IRT communication down to 1 ms cycle time and PROFIsafe Security Class 1.

Technical Specifications

Selection Notes

ST marks the Standard-performance interface variant — pick it when the station's I/O count and cycle-time needs stay within IRT 1-4 ms and 32 modules, and move to an HF interface only if the application needs faster isochronous cycles or a larger station. The bundled BA 2xRJ45 gives a switched two-port connection for line-topology PROFINET wiring without ordering the bus adapter separately, and PROFIsafe Security Class 1 support means the same station can host F-modules for safety I/O alongside standard I/O.

Applications

Building modular PROFINET remote I/O stations that mix standard and fail-safe I/O modules on a single ET 200SP rack, in line or ring (MRP) network topologies.
