It runs on 24 VDC, drawing up to 300 mA, and handles PROFIBUS at up to 12 Mbit/s — fast enough for most distributed I/O applications without bottlenecking the bus cycle. ## Serial protocol and physical layer The RS-232C side uses a 9-pin sub-D socket (female) and supports configurable parity — none, even, or uneven — plus 8 data bits with 1 stop-bit, covering the common asynchronous serial formats a PLC or serial printer expects. When using the 3964(R) protocol, the maximum transmission rate drops to 19.2 kbit/s, which is the protocol overhead limit, not the hardware ceiling. The module also carries an RS-232C (V.24) interface type, so it mates directly with standard PC COM ports or serial terminals without level shifters. ## Environmental and panel fit Rated IP20, so it belongs inside a clean, dry control cabinet — not on a washdown line or outdoors. At about 300 g, it won't stress the DIN rail clip or sag in high-vibration panels. No official successor or pin-compatible alternative is listed; the 6ES7158-0AA01-0XA0 is the active SKU for bridging PROFIBUS DP to RS-232C in the SIMATIC DP family.","metaTitle":"Siemens 6ES7158-0AA01-0XA0 DP/RS 232C Link, 12 Mbit/s","metaDescription":"Siemens SIMATIC DP distributed I/O DP/RS 232C LINK converter, PROFIBUS DP to RS-232C, 24 VDC, 12 Mbit/s, IP20, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Communication Modules"],"specifications":{"Max.":"70 °C","Min.":"-40 °C","Depth":"80 mm","Width":"70 mm","title":"6ES7158-0AA01-0XA0","Height":"95 mm","Parity":"none, even or uneven parity","PROFIBUS DP":"Yes","description":"***Spare part*** SIMATIC DP, distributed I/O DP/RS 232C LINK Converter from PROFIBUS DP to RS 232C interface","Connector type":"9-pin sub D socket","Operation, max.":"95 %; at +25 °C","Weight, approx.":"300 g","lifecycle_stage":"current","Rated value (DC)":"24 V","Interfaces/bus type":"RS 232C (V.24)","IP degree of protection":"IP20","Transmission rate, max.":"12 Mbit/s","Current consumption, max.":"300 mA","Number of start/stop bits":"8 data bits, 1 stop-bit","with 3964 (R) protocol, max.":"19.2 kbit/s"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$634.75","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/599fb3d3d8592ec955b0ddbf0a810439.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=446164&mlfb=6ES7158-0AA01-0XA0"},"ai":{"faq":[{"question":"What serial protocols does the RS-232C port support?","answer":"The port supports standard asynchronous serial with configurable parity (none, even, uneven), 8 data bits, 1 stop-bit, and can run the 3964(R) protocol at up to 19.2 kbit/s."},{"question":"What is the maximum PROFIBUS speed this module can handle?","answer":"It supports PROFIBUS DP at up to 12 Mbit/s, which is the standard maximum for DP networks and fast enough for most distributed I/O applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7158-0AA01-0XA0","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/6ES7158-0AA01-0XA0 when reusing this data.
