Supply is 24 V DC rated, with a typical power loss of 4.5 W across the module — the figure to budget against the backplane when stacking additional I/O cards. ## Where this interface will and will not drop in Configuration is exposed via Dataset, which is the path TIA Portal uses for parameter download; PROFIenergy is not part of the feature set on this firmware. Shared device operation is supported, so one station can be split across two controllers when the topology calls for it. User-data acyclic access via the interface is not provided, and acyclic communication via BU/BA Send is not supported — these paths should not be specified into the project. The minimum PROFINET cycle is 4 ms, which is the value to compare against any IRT-driven axis application that needs faster update. ## Diagnostics on the front face Status is read from three LEDs — RUN in green, ERROR in red, MAINT in yellow — plus a dedicated status indicator, which is enough for a maintenance tech to triage station health at the cabinet without a laptop. Alarms are generated by the module, LLDP neighbor discovery is active, and SNMP is available for higher-level network monitoring — which together let the controls integrator surface port and station faults through the standard PROFINET diagnostic path. TCP/IP and I&M data records I&M0 through I&M3 are supported, so asset identification and basic parameter storage are available out of the box. Lifecycle stage on this MPN is recorded as current, with firmware V3.0.0 shipping on the unit — the BOM line can be specified in good faith without a last-time-buy clock. No official L-stage successor is cross-referenced for this order code; quote the RFQ against the seed MPN itself for the active build.","metaTitle":"6ES7155-5AA00-0AB0 PROFINET interface, 2-port 100 Mbps","metaDescription":"Siemens 6ES7155-5AA00-0AB0 PROFINET interface module for ET 200MP: MRP/IRT, 2-port 100 Mbps switch, 24 V DC, firmware V3.0.0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Communication Modules"],"specifications":{"I2t":"0.09 A²·s","IRT":"Yes","MRP":"Yes","LLDP":"Yes","MRPD":"No","SNMP":"Yes","Depth":"129 mm","Width":"35 mm","Alarms":"Yes","Height":"147 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","Max.
