Siemens 6ES7155-5AA00-0AC0 ET 200MP IM 155-5 PN HF PROFINET 2-Port Remote I/O Interface Module

The Siemens 6ES7155-5AA00-0AC0 is a SIMATIC ET 200MP PROFINET interface module (IM 155-5 PN HF) that connects up to 30 I/O modules to a PROFINET IO controller through an integrated 2-port switch. It runs on 24V DC, supports isochronous mode down to 250 µs, PROFINET system redundancy (S2), and shared device operation with up to four IO controllers.

Technical Specifications

Selection Notes

The HF (High Feature) designation on this interface module adds isochronous real-time (IRT) support down to a 250 µs bus cycle and PROFINET system redundancy (S2), capability the lower-feature ET 200MP interface modules skip - choose this variant when the line needs motion-synchronized I/O or an S7-1500R/H redundant controller pair. The integrated 2-port switch removes the need for a separate PROFINET switch when daisy-chaining stations, and shared-device support for up to four IO controllers lets one ET 200MP station split its modules across independent PLCs.

Applications

Used as the head module for SIMATIC ET 200MP I/O stations in PROFINET-based machine and process automation, particularly where isochronous drive synchronization, media-redundant ring topologies (MRP), or S7-1500H/R controller redundancy are required.
