Siemens 6AG1155-5AA00-2AC0 Interface Module

Applications

ET 200MP Distributed I/O Systems

The 6AG1155-5AA00-2AC0 serves as the communication interface between an ET 200MP station and the higher-level PROFINET automation network. It allows connected ET 200MP I/O modules to exchange process data with the PLC or other PROFINET IO controllers.

Industrial Process Automation

Its SIPLUS construction makes the module suitable for industrial applications where temperature variation, condensation, dust, or chemically active environments may be more demanding than standard control-room conditions.

Factory Automation

The interface module can be deployed in distributed machine-control architectures where I/O stations are positioned close to sensors, actuators, drives, and other field devices.

Machine Building

Machine builders can use the IM 155-5 PN HF as the network interface for ET 200MP stations, creating modular I/O structures that can be expanded according to the machine's requirements.

Redundant PROFINET Architectures

Support for S2 system redundancy and MRP makes the module suitable for automation networks where communication availability and network resilience are important design considerations.

High-Speed Motion and Synchronization Applications

The module supports IRT and isochronous operation, making it appropriate for automation systems requiring tightly coordinated communication and deterministic data exchange.

Advantages

SIPLUS Environmental Protection

The 6AG1155-5AA00-2AC0 is a SIPLUS version with conformal coating. It is designed for more demanding environmental conditions than a standard ET 200MP interface module.

Wide Operating Temperature Range

The specified operating range extends from -40 to +60 °C, providing additional flexibility for installations exposed to low or elevated ambient temperatures.

Integrated Two-Port PROFINET Switch

Two RJ45 Ethernet ports are integrated into the interface module. This simplifies PROFINET network connections and supports common line and network-topology arrangements.

Support for PROFINET IO

The module operates as a PROFINET IO device interface for ET 200MP electronic modules, providing reliable communication between distributed I/O and the automation controller.

MRP Support

Media Redundancy Protocol support allows the module to participate in suitable redundant Ethernet ring architectures, helping maintain network communication if a network connection is interrupted.

IRT and Isochronous Operation

The module supports Isochronous Real-Time communication, with a shortest clock pulse of 125 μs in the documented configuration. This can be valuable for applications requiring highly coordinated cyclic communication.

Flexible ET 200MP Expansion

Up to 12 I/O modules can be operated without an additional system power supply, while configurations can be expanded to as many as 30 I/O modules when additional power supplies are used.

Shared Device Capability

The module supports Shared Device functionality, allowing suitable configurations to share the I/O station between multiple PROFINET IO controllers.

Technical FAQs

1. What is the function of the Siemens 6AG1155-5AA00-2AC0?
It is the IM 155-5 PN HF interface module for the SIPLUS ET 200MP system. It connects ET 200MP electronic modules to a PROFINET IO network and manages communication between the distributed I/O station and the PROFINET controller.

2. What is the difference between this module and the standard 6ES7155-5AA00-0AC0?
The 6AG1155-5AA00-2AC0 is the SIPLUS version based on the 6ES7155-5AA00-0AC0. It adds conformal coating and enhanced environmental capability, including the specified -40 to +60 °C operating range.

3. How is the module connected to PROFINET?
The interface module provides two RJ45 Ethernet ports through its integrated two-port switch. PROFINET communication is established through these Ethernet interfaces using the appropriate network cabling and configured device parameters.

4. How many ET 200MP I/O modules can be connected?
The documented configuration supports up to 12 I/O modules without an additional system power supply and up to 30 I/O modules with additional power supplies. Power segmentation must be designed according to the actual module configuration.

5. Does the 6AG1155-5AA00-2AC0 support Media Redundancy Protocol?
Yes. The interface module supports MRP, allowing it to participate in compatible PROFINET network redundancy arrangements.

6. Can the module be used with IRT applications?
Yes. The IM 155-5 PN HF supports Isochronous Real-Time communication and IRT functions. The complete automation architecture, controller, network configuration, and connected modules must also support the required operating mode.

7. What supply voltage does the interface module require?
The module uses a 24 V DC supply. The documented permissible range is 19.2 to 28.8 V DC, with reverse-polarity and short-circuit protection.

8. How should a PROFINET communication fault be diagnosed?
First inspect the 24 V DC supply, Ethernet cables, RJ45 connectors, network topology, and switch/link indicators. Then check the PROFINET device name, IP configuration, hardware configuration, controller diagnostics, and module status LEDs. Network redundancy settings should also be reviewed when MRP or S2 is being used.

9. Can the 6AG1155-5AA00-2AC0 be configured in TIA Portal?
Yes. The module can be configured and integrated into Siemens engineering environments using the appropriate hardware support and device configuration. The exact TIA Portal version and required device-support package should be verified for the project's hardware and firmware revision.

10. What should be checked when replacing an existing IM 155-5 PN HF?
Verify the complete order number, hardware and firmware compatibility, ET 200MP module configuration, PROFINET device name, network topology, power segmentation, and controller configuration. For a SIPLUS installation, environmental requirements should also be considered when selecting the replacement.
