Siemens PROFINET interface module 6ES7155-6AU02-0BN0

Product Description

It connects the ET 200MP station to PROFINET networks with high-performance communication, supporting IRT (Isochronous Real-Time) for deterministic data exchange. This module enables seamless integration into SIMATIC S7-1500 and other PROFINET controllers, offering a compact and robust solution for industrial automation applications. With a maximum of 32 I/O modules per station, the IM 155-6 PN HF provides extensive scalability for various signal types, including digital, analog, and technology modules. It features a backplane bus current of up to 1.5 A, ensuring reliable power distribution to connected modules. The module supports a wide range of PROFINET features such as Media Redundancy Protocol (MRP), prioritized startup, and shared device functionality, making it suitable for advanced automation architectures. The 6ES7155-6AU02-0BN0 is designed for easy installation on a DIN rail, with a compact form factor that saves cabinet space. It includes an integrated PROFINET switch with two ports, allowing for simple line or ring topologies without additional switches. The module is fully compatible with TIA Portal for configuration and diagnostics, simplifying engineering and maintenance. As a genuine Siemens product, it ensures high reliability and long-term availability, backed by Siemens' global support network. The Siemens 6ES7155-6AU02-0BN0 is an IM 155-6 PN HF interface module designed for the ET 200MP distributed I/O system.
