Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 6ES7155-6AU01-0BN0 is a Siemens SIMATIC ET 200SP interface module that provides a 2-port PROFINET switch with integrated IRT support (250 µs to 4 ms in 125 µs frames), MRP, LLDP, and SNMP. It draws 1.9 W and mounts on a Basic Unit, measuring 50 mm wide by 117 mm high by 74 mm deep. RoHS-compliant since 28-04-17. This interface module acts as the PROFINET IO gateway for an ET 200SP station, handling real-time communication between the controller and distributed I/O. The 2-port switch allows line topology without an external switch, and IRT (Isochronous Real-Time) with 250 µs to 4 ms cycle times in 125 µs increments supports motion control and high-speed applications. MRP (Media Redundancy Protocol) enables ring topologies for network fault tolerance, while LLDP and SNMP provide network diagnostics and asset management. The module supports PROFINET alarms, diagnostics, and PROFINET energy (PROFIenergy) for energy management. Firmware version V4.2 is standard, and the module can be updated via the backplane. ## Applications The 6ES7155-6AU01-0BN0 is used in distributed automation systems where PROFINET IRT and redundancy are required — typical on packaging lines, material handling, assembly cells, and process skids. It connects up to 16 ET 200AL modules via the Basic Unit backplane, making it suitable for modular machine designs with mixed I/O types. The MRP support suits ring topologies in plant networks where a single cable break must not stop production. Within the SIMATIC ET 200SP family, this interface module occupies the mid-range position — it offers IRT and MRP but omits Modbus TCP and MRPD (Media Redundancy for Planned Downtime). It is specified by controls engineers who need deterministic PROFINET performance for motion axes but do not require the full redundancy of an MRPD-capable module. The 2-port switch keeps the station compact, avoiding an external switch in the cabinet.","metaTitle":"Siemens 6ES7155-6AU01-0BN0 SIMATIC ET 200SP Interface Module","metaDescription":"Siemens 6ES7155-6AU01-0BN0 SIMATIC ET 200SP interface module, 2 ports, IRT 250 µs, MRP, LLDP, SNMP, 1.9 W, 50 mm wide, RoHS since 28-04-17.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["PLC Communication Modules"],"specifications":{"I2t":"0.09 A²·s","IRT":"Yes; 250 µs to 4 ms in 125 µs frame","MRP":"Yes","LLDP":"Yes","MRPD":"No","SNMP":"Yes","Depth":"74 mm","Width":"50 mm","Alarms":"Yes","Height":"117 mm","TCP/IP":"Yes","RUN LED":"Yes; green LED","100 Mbps":"Yes","I&M data":"Yes; I&M0 to I&M3","ERROR LED":"Yes; red LED","MAINT LED":"Yes; Yellow LED","Modbus TCP":"No","PROFIenergy":"Yes","Via Dataset":"Yes","Autocrossing":"Yes","Shared device":"Yes","Security level":"According to Security Level 1 Test Cases V1.1.1","via BU/BA Send":"Yes; + 16 ET 200AL modules","Autonegotiation":"Yes","Number of ports":"2","Weight, approx.":"147 g; without BusAdapter","lifecycle_stage":"current","Firmware version":"V4.2","Isochronous mode":"No","Media redundancy":"Yes; PROFINET MRP","Power loss, typ.":"1.9 W","RJ 45 (Ethernet)":"Yes","Rated value (DC)":"24 V","Status indicator":"Yes","Integrated Switch":"Yes","FW update possible":"Yes","PROFINET IO Device":"Yes","Prioritized startup":"Yes","Diagnostics function":"Yes","HW functional status":"From FS03","Inrush current, max.":"3.7 A","BusAdapter (PROFINET)":"Yes; BA 2x RJ45, BA 2x FC, BA 2x M12","Isolation tested with":"707 V DC (type test)","Network loading class":"2","Open IE communication":"Yes","Transmission procedure":"PROFINET with 100 Mbit/s full duplex (100BASE-TX)","Short-circuit protection":"Yes","Current consumption, max.":"550 mA","Between Different Circuits":"Safety extra low voltage SELV","Reverse polarity protection":"Yes","Vertical Installation, Max.":"50 °C","Vertical Installation, Min.":"-30 °C; No condensation","Connection display LINK TX/RX":"Yes; 2x green link LEDs on BusAdapter","Horizontal Installation, Max.":"60 °C","Horizontal Installation, Min.":"-30 °C; No condensation","Number of PROFINET interfaces":"1; 2 ports (switch)","Address space per module, max.":"256 byte; For input and output data respectively","Address space per station, max.":"512 byte","PROFINET system redundancy (S2)":"No","Current consumption (rated value)":"450 mA","permissible range, lower limit (DC)":"19.2 V","permissible range, upper limit (DC)":"28.8 V","Between Backplane Bus And Electronics":"No","Between Supply And All Other Circuits":"No","Number of submodules per station, max.":"256","PROFINET from GSD version/GSD revision":"GSDML V2.35","between PROFINET and all other circuits":"Yes; 1500 V AC (type test)","Mains/voltage failure stored energy time":"10 ms","Monitoring of the supply voltage (PWR-LED)":"Yes; green PWR LED","Installation altitude above sea level, max.":"5 000 m; Restrictions for installation altitudes > 2 000 m, see manual","Quantity of operable ET 200AL modules, max.":"16","Quantity of operable ET 200SP modules, max.":"32","STEP 7 configurable/integrated from version":"V5.5 SP4","Module swapping during operation (hot swapping)":"Yes; Single hot swapping","Number of IO Controllers with shared device, max.":"2","STEP 7 TIA Portal configurable/integrated from version":"V14"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$144.78","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/cc855938c5bc0c68442c9fe092f09bd6.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=1024785&mlfb=6ES7155-6AU01-0BN0"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7155-6AU01-0BN0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/6ES7155-6AU01-0BN0 when reusing this data.
