It serves as the PROFINET gateway, linking up to 63 electronic, power, or motor starter modules (total width up to 2 m) to a higher-level controller via two RJ45 ports at 100 Mbit/s. Two RJ45 ports enable line or ring topology; with MRP you get media redundancy failover within milliseconds. For time-synchronized application – like coordinated drive motion – IRT delivers deterministic cycle times. ARP handles automatic replacement of a failed module without project engineering: swap the hardware, the IO controller picks up the new device. Data volume caps at 256 bytes input and 256 bytes output. Power consumption is 3.3 W typical. The module holds its power-up state for 20 ms after a mains dip – long enough to ride through short grid glitches without a processor restart. Dimensions are 60 x 119.5 x 75 mm, occupying a single ET 200S base unit slot. ## What this module is NOT This module is an interface for ET 200S, not a programmable controller. It operates from 0 °C to 60 °C. UL approval and CE mark are noted in the spec.","metaTitle":"Siemens 6ES7151-3AA23-0AB0 IM 151-3 PN ST, 2-Port PROFINET","metaDescription":"Interface module for ET 200S, 2 RJ45, 100 Mbit/s, supports IRT/ARP/MRP.
