Product Overview

Siemens 6GK1415-2BA10 DP/AS-i Link Advanced Upgrade: Seamless Transition from Legacy AS-Interface Gateways

The Siemens 6GK1415-2BA10 DP/AS-i Link Advanced is a PROFIBUS DP to AS-Interface gateway module within the SIMATIC NET communication family. It serves as the critical bridge between a PROFIBUS DP master — typically a SIMATIC S7-300, S7-400, or S7-1500 PLC — and an AS-Interface (AS-i) network carrying distributed field devices such as sensors, actuators, solenoid valves, and indicator lights. For facilities running aging control architectures built around earlier DP/AS-i Link modules or discontinued SIMATIC NET gateways, the 6GK1415-2BA10 represents a direct, field-proven upgrade path that preserves existing wiring infrastructure, AS-i slave addressing, and PROFIBUS GSD configuration files.

Many industrial sites still operate PROFIBUS DP segments originally commissioned in the early 2000s. When the legacy DP/AS-i Link 20E or earlier 6GK1415-series variants reach end-of-life or become unavailable as spare parts, production teams face pressure to source a compatible replacement without triggering a full rewiring campaign or PLC program overhaul. The 6GK1415-2BA10 addresses this challenge directly: it retains the same PROFIBUS DP slave interface, supports the same AS-i specification V3.0 protocol, and fits standard DIN-rail mounting in the existing control cabinet footprint. Engineers can swap the module, re-import the GSD file into STEP 7 or TIA Portal, and restore AS-i segment communication with minimal downtime.

During a typical retrofit, the 6GK1415-2BA10 is installed alongside other SIMATIC NET components. The PROFIBUS DP segment connecting the module to the S7-300 or S7-400 CPU may also include CP 342-5 or CP 443-5 communication processors, and the AS-i segment downstream commonly carries AS-i Power Supply units (e.g., 3RX9501 series) that provide the combined data and 30 V DC power on the yellow AS-i flat cable. Replacing the gateway does not require re-addressing AS-i slaves or modifying the AS-i master configuration stored in the module, provided the new unit is configured with the same slave address list and projection data.

For sites migrating from a SIMATIC S7-300 rack to a newer S7-1500 or ET 200SP distributed I/O architecture, the 6GK1415-2BA10 can continue to serve as the AS-i gateway while the PROFIBUS DP master role is taken over by a CM 1542-5 communication module or a PROFIBUS interface on the ET 200SP IM 155-5 DP interface module. This hybrid approach allows phased migration: the AS-i field wiring and slave devices remain untouched while the controller platform is modernized. Only the PROFIBUS DP master address and baud rate settings need to be verified during commissioning.

Physical installation is straightforward. The 6GK1415-2BA10 mounts on a standard 35 mm DIN rail and requires a 24 V DC auxiliary supply via the integrated power connector. The PROFIBUS DP port uses a standard 9-pin Sub-D connector compatible with existing PROFIBUS cables and connectors already installed in the cabinet. The AS-i port connects directly to the AS-i flat cable via the integrated piercing connector, eliminating the need for additional terminal blocks or adapters. Cabinet space requirements are comparable to the predecessor modules, making physical fit a non-issue in most retrofit scenarios.

From a programming perspective, the module appears to the PROFIBUS DP master as a standard DP slave. In STEP 7 Classic, the GSD file is imported into the hardware catalog and the module is configured in HW Config. In TIA Portal, the same process applies through the device catalog. The AS-i slave input and output data are mapped to the PLC’s process image automatically, and existing OB1 or FC logic referencing those I/O addresses requires no modification as long as the data mapping is preserved during the GSD import. This is a key advantage for facilities where the original PLC programmer is no longer available and source code documentation is incomplete.

For multi-segment AS-i installations, multiple 6GK1415-2BA10 modules can be deployed on the same PROFIBUS DP segment, each managing an independent AS-i network of up to 31 standard slaves or 62 A/B slaves. This architecture is common in automotive body shop lines, packaging machinery, and conveyor systems where large numbers of binary sensors and actuators are distributed across the production floor. Each module operates independently, and a fault on one AS-i segment does not propagate to adjacent segments or to the PROFIBUS DP backbone.

Procurement teams evaluating this replacement should also consider stocking related consumables and spare modules to support ongoing maintenance. Commonly paired items include PROFIBUS DP bus connectors (e.g., 6ES7972-0BA52-0XA0), PROFIBUS cables, AS-i flat cable termination plugs, and AS-i diagnostic repeaters for long cable runs. Having a tested spare 6GK1415-2BA10 on the shelf eliminates the risk of extended downtime caused by a single module failure in a critical production segment.

Seamless Upgrade Solutions

A complete AS-i segment modernization typically involves more than just the gateway module. When replacing the 6GK1415-2BA10, engineers should audit the entire communication chain. The PROFIBUS DP backbone connecting the module to the S7-300 or S7-400 CPU rack may benefit from replacing aging bus connectors and terminating resistors. If the controller is being upgraded simultaneously, a CM 1542-5 PROFIBUS communication module for the S7-1500 or an IM 155-5 DP interface module for an ET 200SP distributed I/O station can take over the PROFIBUS DP master role without disrupting the AS-i field wiring downstream.

On the AS-i side, the 3RX9501 AS-i Power Supply provides the 30 V DC power and data signal on the AS-i flat cable. If the existing power supply is aging or undersized for an expanded slave count, replacing it in parallel with the gateway module is recommended to avoid a second maintenance window. AS-i diagnostic repeaters extend cable runs beyond the standard 100 m limit and should be inspected for firmware compatibility with AS-i V3.0 slaves. Individual AS-i I/O modules — such as compact 4DI/4DO AS-i slave modules — can be added to the segment to expand digital I/O capacity without modifying the PROFIBUS DP configuration, as the 6GK1415-2BA10 automatically detects new slaves during the projection phase.

For sites that also operate SIMATIC HMI panels (e.g., TP700 Comfort or KTP900 Basic) connected to the same S7 controller, the HMI project does not require modification when replacing the gateway, since the AS-i data is transparent to the HMI through the PLC’s process image. Programming cables such as the PC Adapter USB A2 (6ES7972-0CB20-0XA0) are useful during commissioning to connect a laptop to the PROFIBUS DP segment for diagnostic purposes using STEP 7 or TIA Portal online functions.

Retrofit Guidance FAQ

Q: Do I need to re-address AS-i slaves after replacing the 6GK1415-2BA10?
A: No. AS-i slave addresses are stored in the slaves themselves, not in the gateway. After replacing the module and importing the GSD file, the new gateway will detect all existing slaves at their current addresses during the startup projection phase.

Q: Is the PROFIBUS DP wiring compatible with the new module?
A: Yes. The 6GK1415-2BA10 uses a standard 9-pin Sub-D PROFIBUS connector. Existing cables, connectors, and terminating resistors are fully reusable.

Q: Can I use the same GSD file from the predecessor module?
A: No. The 6GK1415-2BA10 has its own GSD file that must be imported into STEP 7 or TIA Portal. The hardware configuration must be updated, but the I/O address mapping can be preserved to avoid PLC program changes.

Q: What PROFIBUS baud rates are supported?
A: The module supports all standard PROFIBUS DP baud rates up to 12 Mbit/s, consistent with the predecessor module.

Q: Is the module compatible with AS-i V2.1 slaves already installed in the field?
A: Yes. AS-i V3.0 is fully backward compatible with V2.1 and V2.0 slaves. No slave replacement is required.

Q: How long does commissioning typically take?
A: For a direct replacement with no wiring changes, experienced engineers typically complete commissioning — including GSD import, hardware configuration download, and AS-i segment projection — within 2 to 4 hours per segment.
