IRT operates in frame intervals from 250 µs to 4 ms, selectable in 125 µs increments, making this module suitable for motion-control and high-speed synchronization applications where deterministic timing is required. The I2t rating of 0.25 A²·s is a thermal let-through energy value for the module's internal protection; reference it when sizing upstream branch-circuit protection. ## Network Integration Two PROFINET ports via a plug-in BusAdapter support line or ring topologies; autocrossing and auto-negotiation are standard. LLDP and SNMP are available for network management, and the module supports shared-device configurations and H-Sync forwarding. Alarm generation, I&M data (I&M0 to I&M3), and PROFIenergy are built in. PROFIsafe via a dataset is supported, but MRPD is not. Maximum cycle time is 4 ms. Status and diagnostics are indicated by RUN (green), ERROR (red), and MAINT (yellow) LEDs on the front face.","metaTitle":"Siemens 6ES7155-6AU01-0CN0 ET 200SP PROFINET Bus Adapter, IR","metaDescription":"Current lifecycle Siemens 6ES7155-6AU01-0CN0 ET 200SP PROFINET bus adapter supports IRT (250 µs to 4 ms in 125 µs frame), MRP, SNMP, 2 ports via BusAdapter, 2.4 W.
