Configured for distributed input and output connectivity in PROFINET networks, the SIEMENS 6ES7155-6AU01-0BN0, also cataloged as the IM 155-6PN Standard Interface Module, operates as a dedicated hardware controller for SIMATIC ET 200SP rack assemblies.

Hardware Configuration and System Architecture

The 6ES7155-6AU01-0BN0 manages data exchange between a higher-level PLC controller and up to 32 standard ET 200SP I/O modules plus 16 ET 200AL expansion modules over the internal backplane bus. The module supports single hot-swap operations for replacing active I/O modules without powering down the entire station rack.

Hardware Specifications

PROFINET Communication and Bus Management

The IM 155-6PN Standard module handles deterministic PROFINET IO communication protocol execution, synchronizing cyclical process data between field sensors and the central controller. It coordinates module parameter assignment, diagnostic reporting, and backplane power distribution, maintaining communication integrity across distributed station architectures.

Scope of Delivery

• 1 x SIEMENS 6ES7155-6AU01-0BN0 Interface Module
• 1 x Server Module (6ES7193-6PA00-0AA0)

Installation and Field Wiring Guidelines

• Mounting Procedure: Mount the interface module onto a standard 35 mm DIN rail on the leftmost slot of the ET 200SP station assembly.
• Server Module Requirement: Ensure the included server module (6ES7193-6PA00-0AA0) is plugged into the rightmost terminal position to terminate the backplane bus properly.
• PROFINET Cabling: Connect shielded Industrial Ethernet copper cables with RJ45 plugs or appropriate BusAdapters to the interface module ports.
• Power Supply Integration: Supply nominal 24 VDC power through the designated power terminal block on the base unit to energize the interface module and backplane bus.
