Siemens 6ES7155-5AA01-0AB0 SIMATIC ET 200MP IM 155-5 PN ST PROFINET Interface Module, 24V DC

High‑performance PROFINET interface module for SIMATIC ET 200MP distributed I/O systems, connecting up to 30 electronic modules with integrated 2‑port switch and IRT communication for real‑time automation.

The Siemens 6ES7155-5AA01-0AB0 is an IM 155-5 PN ST PROFINET IO-Device Interface Module for the ET 200MP distributed I/O system. It is the central network node for connecting ET 200MP I/O modules to a PROFINET network, handling the data exchange with a higher-level controller (e.g., S7-1500 CPU). Powered by a 24V DC supply, this space‑efficient module (35 mm wide) features an integrated 2‑port switch, enabling flexible line and ring topologies, and supports isochronous real‑time (IRT) communication with a minimum bus cycle time of 250 µs for high‑speed, deterministic data exchange. It supports essential PROFINET functions such as Media Redundancy Protocol (MRP), Shared Device for up to two IO‑Controllers, and Fast Start‑Up (FSU) with 500 ms for fast I/O recovery.

Applications

• High‑speed distributed I/O nodes in production lines and packaging machinery

• Real‑time process control requiring IRT communication (e.g., motion control, printing presses)

• Modular, scalable I/O stations for S7‑1500-based automation systems

• Centralized machine control cabinets and decentralized field installations

• Upgrade of existing ET 200MP systems or replacement for IM 155-5 PN BA/ST modules

Key Features

• PROFINET IO Device Interface – Connects ET 200MP I/O modules to PROFINET networks; supports RT and IRT

• Integrated 2‑Port Switch – Supports line and ring topologies; two RJ45 ports for flexible wiring

• High I/O Capacity & Expandability – Up to 30 I/O modules per station with an additional power supply; up to 12 I/O modules without an additional PS

• Isochronous Real‑Time (IRT) – Bus cycle time down to 250 µs enables deterministic, high-speed data synchronization for demanding motion and positioning applications

• Shared Device Function – Supports up to two PROFINET IO Controllers accessing the same station; ideal for submodule‑level data exchange

• Online Firmware Update (FW‑Update) – Firmware can be updated via the network without removing the module

• Media Redundancy Protocol (MRP) – Increases network availability by reconfiguring ring topologies in the event of an interruption

• Fast Start‑Up (FSU) – Startup time of 500 ms; reduces downtime for applications requiring rapid recovery of I/O

• I&M Identification Data – Supports I&M0 to I&M3 for electronic nameplate and online maintenance identification

• Comprehensive Diagnostics & System Integration – Reverse polarity, short‑circuit and mains buffering (10 ms)

System Integration

• I/O System: SIMATIC ET 200MP platform (used with S7‑1500 and ET 200MP I/O modules)

• Controllers: SIMATIC S7‑1500 CPUs (e.g., 6ES7515‑2AM01‑0AB0), via PROFINET

• Engineering: TIA Portal V14 SP1 (or higher) via HSP (Hardware Support Package)

• Power Supply: 24 V DC (20.4‑28.8 V DC), rated current 0.2 A, backplane bus power: 14 W

Technical Specifications

Configuration & Licensing Notes

• TIA Portal – Integrated hardware support requires TIA Portal V14 or higher with Hardware Support Package (HSP 0223)

• GSDML File – For planning with older TIA Portal versions or third‑party controllers, the module is configurable via a GSDML (V2.32)

• Shared Device Function – Requires GSD file configuration and supports up to two IO‑Controllers (submodule‑level sharing)

• Hot‑Swapping – Replacement of modules during operation requires appropriate I/O module design (no hot‑swap for the interface module itself)
