Siemens 6AG2155-5AA01-4AB0 PROFINET Interface Module

Where It Excels in Industrial Use

• Railway automation systems: Provides a robust PROFINET interface for ET 200MP distributed I/O stations used in railway control and monitoring equipment.
• Harsh industrial installations: The conformal-coated SIPLUS construction is suited to environments exposed to temperature variation, condensation, chemically active substances, salt mist, and other demanding conditions.
• Distributed machine control: Connects ET 200MP electronic modules to a higher-level PROFINET IO controller while maintaining a compact and modular station architecture.
• Large distributed I/O stations: Supports up to 12 I/O modules without an additional power supply and up to 30 I/O modules when additional power supplies are installed.
• Redundant network architectures: MRP, Shared Device, and related PROFINET functions make the module suitable for network designs requiring improved availability and flexible controller connectivity.
• Time-critical automation: IRT and isochronous operation provide deterministic communication capabilities for applications requiring tightly synchronized process data exchange.

Key Strengths at a Glance

• Railway-oriented SIPLUS design: Developed from the SIMATIC ET 200MP IM 155-5 PN ST platform with conformal coating and an extended environmental operating range.
• Extended temperature capability: Supports operation from -40 to +70 °C, with short-duration operation up to +85 °C for 10 minutes under the specified ST1/ST2 conditions.
• Integrated two-port switch: Two RJ45 ports simplify PROFINET network connections and allow practical network integration without a separate external switch for basic line configurations.
• Flexible PROFINET communication: Supports PROFINET IO, MRP, Shared Device, IRT, and isochronous operation for demanding distributed automation systems.
• Scalable station architecture: Supports up to 30 ET 200MP I/O modules when additional system power supplies are used.
• Advanced diagnostics: RUN, ERROR, MAINT, and port link/activity indicators provide convenient local status information for commissioning and troubleshooting.
• Engineering flexibility: Supports I&M0 to I&M3 identification and maintenance data, helping simplify device identification and service management.
