It operates on a 24 V DC supply with a typical power loss of 2.4 W and ships with firmware V6.0. Notable limitations for selection: IRT (Isochronous Real-Time) is not supported, so this module is best suited for standard PROFINET applications rather than motion control with strict timing. The listed I2t of 0.36 A²·s gives the inrush energy let-through for power supply fusing coordination. Firmware V6.0 is the current release, ensuring compatibility with recent TIA Portal versions and IO controllers. Identification data (I&M0 to I&M3) is supported for asset tracking. ## Key protocol and diagnostic features Supports MRP (Media Redundancy Protocol) for ring topology failover, but not MRPD (Media Redundancy for Planned Duplication). Shared device is not available; each module serves a single IO controller. LLDP and SNMP are enabled for network management. Autocrossing and autonegotiation on the Ethernet ports simplify cabling. Diagnostics, alarms, and status indicators are standard.","metaTitle":"Siemens 6ES7155-6AU00-0HM0 PROFINET Interface, 2-Port, MRP","metaDescription":"Siemens 6ES7155-6AU00-0HM0 PROFINET IO Device with integrated 2-port switch, MRP support, firmware V6.0. 24 V DC, 2.4 W typical.
