The Siemens 6ES7155-6AU00-0CN0 is the PROFINET IO interface module for the ET 200SP distributed I/O system. It provides two RJ45 ports with an integrated switch, supports PROFINET IRT with a high-performance mode enabling cycle times down to 125 µs in 125 µs frame increments, and handles media redundancy via MRP. The module runs on 24 V DC and draws 2.4 W typical. For applications requiring deterministic motion control or isochronous data exchange, the IRT capability with 1 µs jitter makes this interface suited for synchronized axes in multi-drive cells. The I2t rating of 0.09 A²·s defines the surge current capability at the power input — a number to match when sizing the upstream 24 V DC circuit breaker or fuse.
