6GK1415-2AA10 Siemens DP/AS-Interface Link 20E Gateway

Introduction to the 6GK1415-2AA10

When a production line demands reliable communication between a PROFIBUS DP controller and AS-Interface field devices, the 6GK1415-2AA10 from Siemens provides a proven gateway solution. This DP/AS-Interface Link 20E is designed according to AS-Interface specification V3.0, ensuring compatibility with modern AS-i networks. As part of the SIMATIC NET family, it bridges the gap between higher-level PROFIBUS systems and the cost-effective AS-i sensor/actuator level.

One distinctive feature is the support for up to 62 AS-i slaves with a bus cycle time of just 10 ms, enabling fast data exchange in large AS-i networks. Additionally, the device offers galvanic isolation, which helps protect the PROFIBUS side from potential ground loops or voltage spikes on the AS-i side.

Applications and Use Cases

The 6GK1415-2AA10For example, in an automotive assembly line, this gateway can connect multiple AS-i nodes—such as presence sensors, pushbuttons, and indicator lights—to a central PLC. Moreover, its IP20 rating makes it suitable for installation in control cabinets, where it can be easily mounted on a standard DIN rail. The device also supports the ASIsafe protocol? No, it does not support ASIsafe, so it is not suitable for safety-related functions. However, for standard automation tasks, it provides a cost-effective and reliable bridge.

Installation and Setup

Installing the 6GK1415-2AA10 is straightforward. The device snaps onto a 35 mm DIN rail, and all AS-Interface connections are made via screw terminals, ensuring secure wiring. The PROFIBUS interface uses a standard RS-485 connection. Configuration can be performed using the pushbutton on the device, STEP7, GSD files, or the command interface. For initial setup, ensure that the AS-i power supply is within the specified range (30 V, max 200 mA consumption) and that the bus cycle time is set according to the number of slaves (5 ms for 31 slaves, 10 ms for 62 slaves). Always refer to the official Siemens manual for detailed wiring and configuration steps.

Maintenance and Reliability

To maintain reliable operation, periodic inspection of the gateway is recommended. Check that all screw-type connections are tight and that the device is free from dust and moisture, especially in environments with high humidity (up to 95% at 25 °C). The LED indicators (PWR, APF, CER, AUP, CM, BF, SF) provide a quick visual status of power, AS-i communication, and PROFIBUS link. Regular monitoring of these LEDs can help detect issues early. Since the device has no moving parts, maintenance is minimal, but environmental conditions should be kept within the specified temperature ranges (0 to 60 °C horizontal, 0 to 45 °C vertical) to ensure long-term reliability.

Compatibility and Integration

The 6GK1415-2AA10 is designed for PROFIBUS DP networks, supporting the PROFIBUS protocol. It is not compatible with PROFINET, Industrial Ethernet, or wireless interfaces, as these are not supported. The device acts as a PROFIBUS DP slave and an AS-Interface master, allowing seamless integration into existing Siemens automation systems. It supports the AS-Interface master profile M4, which is compliant with AS-Interface V3.0. For analog I/O data, access is via data record transfer, while digital I/O data is accessed through the process image or peripheral addresses. This makes it a flexible solution for mixed digital and analog AS-i devices.

Troubleshooting and Common Issues

If the 6GK1415-2AA10 fails to communicate, first check the LED indicators. A lit BF (bus fault) LED indicates a PROFIBUS issue, while a lit APF (AS-i power failure) LED points to a power problem on the AS-i side. Verify that the AS-i power supply is providing 30 V and that the current consumption does not exceed 200 mA. Also, ensure that the number of AS-i slaves does not exceed 62, as this can cause bus cycle time errors. If the device is not recognized by STEP7, confirm that the correct GSD file is installed and that the PROFIBUS address is set correctly. For persistent issues, consult the Siemens support documentation or contact AutoDCSTech for assistance.
