Siemens 6ES7155-6BA01-0CN0 Profibus DP Interface Module

The Siemens 6ES7155-6BA01-0CN0 IM 155-6 DP HF interface module serves as the PROFIBUS DP gateway for the SIMATIC ET 200SP distributed I/O system, enabling an ET 200SP node to communicate on a PROFIBUS DP network. This single-slot interface is part of the ET 200SP PROFIBUS bundle IM and provides one PROFIBUS DP interface with a green DP status LED for at-a-glance wiring and operation feedback. The PROFIBUS DP address is configured via the module’s address switches, and the device is designed to connect the ET 200SP I/O system to a DP backbone, facilitating centralized control and diagnostics in industrial automation environments. In DPV1 configurations, the HF variant supports extended parameter data (more than 244 bytes) under appropriate project settings (for example STEP 7 V5.5 SP3 with HSP 242), enabling richer device parameter exchanges on the DP network. Typical applications include integrating ET 200SP I/O blocks with a PLC or controller over PROFIBUS DP, allowing seamless data exchange, monitoring, and control across a factory floor. The 6ES7155-6BA01-0CN0 designation identifies this specific DP HF module built for the ET 200SP ecosystem, ensuring compatibility with Siemens automation architectures and the broader PROFIBUS DP landscape.
