The Siemens 6ES7155-6AU00-0BN0 is a PROFINET interface module for the SIMATIC ET 200SP distributed I/O system. It acts as the central control unit of a remote I/O station, managing data exchange for up to 32 I/O modules within the station and enabling real‑time communication with the PROFINET master.
1. Built-in device-level switching function, supporting direct data forwarding without the need for additional configuration of an independent switch.
2. The Siemens 6ES7155-6AU00-0BN0 supports linear and ring topologies, has MRP medium redundancy function, and the ring network fault recovery time is less than 200ms, significantly enhancing network reliability.
3. Supports synchronous real-time communication with equal time, with a cycle time of less than 1ms, suitable for high-speed motion control and precise synchronization scenarios.
4. Supports automatic topology identification, automatic negotiation, and cross-wire sequence adaptation, without the need for manual configuration of network parameters.
The single station has a maximum expansion capacity of 32 modules, significantly saving space in the control cabinet.
The Siemens 6ES7155-6AU00-0BN0 supports the on-the-fly insertion and replacement of I/O modules without the need to shut down the system and reconfigure the state, ensuring production continuity.
When replacing modules, it automatically matches the original configuration data, achieving true plug-and-play.
Supports multiple power supply architectures, and can independently turn off the power supply of a certain group of I/O, facilitating segmented maintenance and management.
Multi-level LED status indication:
The panel integrates RUN (operation), ERROR (fault), and Link (link) three-level indicator lights, making the on-site status clear at a glance.
Channel-level deep diagnosis:
Supports precise location of faults to each module and each channel, and supports remote diagnosis, significantly reducing troubleshooting time.
Power status monitoring:
Real-time detection of the 24V power supply status of each I/O module and feedback through byte mapping to the controller.
Firmware online upgrade:
The Siemens 6ES7155-6AU00-0BN0 can be remotely upgraded with firmware through the TIA Portal B&R software, without the need to disassemble the equipment.
I&M data storage:
Built-in identification and maintenance (I&M) data such as device identification, serial number, and firmware version, facilitating factory full lifecycle asset management.
In the TIA Portal view, find M 155-6 PN ST from the hardware directory, with the order number 6ES7155-6AU01-0BN0. Drag it to the network view and assign a PROFINET device name and IP address to it.
Yes, the Single Hot Swap function is supported, allowing the replacement of I/O modules during system operation without interrupting the communication of the remaining modules.
It has been gradually discontinued. The direct replacement model is 6ES7155-6AU01-0BN0. The replacement model is functionally fully compatible and even has improved performance, and the configuration and wiring can be directly replaced without any modifications.
Diagnostic alarm causes CPU stop
When the interface module detects an error and triggers a diagnostic interrupt, if the CPU program does not contain the corresponding diagnostic interrupt organization block (OB82) to handle the event, the CPU may enter STOP mode due to the unhandled interrupt.
Firmware version mismatch error
If a "firmware version mismatch" message appears, the issue can be resolved by:
Upgrading TIA Portal to a newer version (which includes an updated hardware database);
Installing the latest Hardware Support Package (HSP) in the current TIA Portal version;
In the module properties, enabling the option "Allow firmware version compatible with configuration".
