The 6ES7155-6AA01-0BN0 is the IM155-6PN ST standard interface module for the SIMATIC ET 200SP distributed I/O system. This module supports the PROFINET IO protocol, features high communication speed and determinism, and can be expanded to support up to 32 peripheral modules and 16 ET 200AL modules per station, making it suitable for compact automation edge communication scenarios.
Adopts BusAdapter technology
Supports single-module hot swapping
Supports direct connection of up to 16 ET 200AL modules
The 6ES7155-6AA01-0BN0 is a highly modular PROFINET interface station bundle designed for modern distributed industrial automation architectures. As a comprehensive communication terminal, this bundle integrates three essential components, the IM 155-6 PN ST interface module for high-speed data exchange, the BA 2xRJ45 BusAdapter for flexible physical network connectivity, and a Server Module to provide the necessary physical termination for the backplane bus.Regarding system scalability, this module demonstrates superior compatibility. A single station can support up to 32 ET 200SP I/O modules and further extend to include 16 ET 200AL series modules via dedicated cables, enabling a seamless transition from in-cabinet to out-of-cabinet (IP67) wiring. Furthermore, the system supports Single Hot Swap functionality, allowing technicians to replace faulty I/O modules under power without interrupting the entire station's operation. This significantly reduces maintenance downtime and ensures high availability and continuity for industrial control processes.

When using the 6ES7155-6AA01-0BN0, system stability depends on proper hardware configuration and accurate network identification. It is critical to ensure the Server Module is installed at the end of the station. Otherwise, the backplane bus will not terminate, resulting in system errors. You must use the correct BusAdapter model to match the communication interface and accurately assign the PROFINET Device Name in TIA Portal, as this is the unique identifier for the PLC. Additionally, while hot swapping is supported, frequent operation should be avoided, and ensure the power grouping of BaseUnits (light vs. dark) is correctly configured to meet the power requirements of the I/O modules.
It is a PROFINET interface module (Standard) for the SIMATIC ET 200SP distributed I/O system, responsible for data exchange between the controller (PLC) and I/O modules.
What is the main purpose of the 6ES7155-6AA01-0BN0?
It is used to connect remote I/O stations to a PROFINET network, enabling the PLC to control sensors and actuators on remote machinery.
How to install the 6ES7155-6AA01-0BN0?
Snap it onto a standard DIN rail, connect the network cable via a BusAdapter, and plug various ET 200SP I/O modules directly to its right side.
How many expansion modules does the 6ES7155-6AA01-0BN0 support?
As a standard module, it supports the connection of up to 32 ET 200SP I/O modules.
Does the 6ES7155-6AA01-0BN0 require a separate power supply?
Yes, it typically requires a 24V DC power supply for its own operation and backplane bus communication.
