Siemens 6AG1155-6AU01-7CN0 Interface Module

Applications

The Siemens 6AG1155-6AU01-7CN0 is a SIPLUS ET 200SP IM 155-6 PN/2 HF interface module designed for high-performance distributed I/O systems. Based on the Siemens 6ES7155-6AU01-0CN0 platform, it provides a PROFINET connection between an ET 200SP station and a higher-level automation controller.

With support for up to 64 I/O modules and 16 ET 200AL modules, the module can be used for both compact machine-control systems and larger distributed automation stations.

Distributed I/O Automation

The module is suitable for Siemens S7-based automation systems where I/O devices need to be installed close to machines, production lines, or process equipment rather than concentrated in a central control cabinet.

Machine Building

The compact ET 200SP architecture makes the 6AG1155-6AU01-7CN0 suitable for packaging machinery, assembly equipment, material handling, production machines, and automated inspection systems.

High-Speed Industrial Communication

Its High Feature architecture supports fast PROFINET communication with update times down to 0.25 ms, making it appropriate for applications requiring deterministic data exchange between the controller and distributed I/O.

High-Availability Systems

The interface module supports S2 system redundancy, allowing it to be considered for automation applications where communication availability is an important part of the system design.

Harsh Industrial Environments

Unlike a standard ET 200SP interface module, this SIPLUS version uses conformal coating and supports an operating temperature range of -40 to +70 °C, making it suitable for demanding industrial environments.

Synchronized Automation

The 6AG1155-6AU01-7CN0 supports isochronous mode, making it useful in applications where predictable communication timing and synchronization are important.

Flexible Distributed Stations

The module can manage a substantial ET 200SP station, supporting up to 64 I/O modules plus 16 ET 200AL modules. This provides system integrators with considerable flexibility when designing distributed control architectures.

Advantages

SIPLUS Environmental Protection

The conformal-coated design provides additional protection for the electronics compared with standard industrial modules. Combined with the extended temperature range, this makes the module a strong choice for demanding installations.

High Feature PROFINET Interface

The IM 155-6 PN/2 HF architecture provides two PROFINET ports through a compatible BusAdapter, allowing the module to integrate efficiently into distributed Ethernet-based control networks.

S2 System Redundancy

S2 redundancy is an important advantage for systems where loss of communication between the controller and remote I/O could result in production interruption.

Multi-Hot-Swapping

The module supports multi-hot-swapping, which can simplify maintenance in appropriately configured ET 200SP systems and reduce downtime during component replacement.

Fast Update Performance

With a minimum update time of 0.25 ms, the module is designed for demanding cyclic PROFINET applications where rapid I/O communication is required.

Isochronous Mode

Isochronous operation allows the module to participate in applications requiring deterministic communication timing and coordinated control behavior.

Large Station Capacity

Supporting up to 64 I/O modules and 16 ET 200AL modules allows a single interface module to serve a relatively large distributed I/O station.

Flexible BusAdapter Configuration

The BusAdapter architecture allows different PROFINET connection solutions to be selected according to the installation and network cabling requirements.
