Profibus DP Gateway Solution — TURCK BL67-GW-DP | BL67 Series
Where This Product Is Used
The TURCK BL67-GW-DP serves as the fieldbus communication head for the BL67 modular remote I/O system, enabling distributed I/O nodes to communicate over a Profibus DP network. Typical deployment environments include:
- Automotive Assembly Lines — Connects distributed sensor/actuator stations on body-in-white, paint shop, and final assembly lines to Siemens S7 or other Profibus masters.
- Packaging & Filling Machinery — Manages I/O for conveyor control, reject gates, and fill-level sensors in high-speed FMCG production.
- Intralogistics & Warehouse Automation — Interfaces sorters, diverters, and barcode scanners in distribution center conveyor systems.
- Process Plants (Chemical / Pharma) — Provides remote I/O connectivity in Ex-zone-adjacent control panels where Profibus DP is the plant standard.
- Machine Tool & Press Lines — Decentralizes I/O from the main control cabinet to reduce wiring runs across large machine beds.
- Water & Wastewater Treatment — Connects field instruments and valve actuators to SCADA systems via Profibus DP backbone.

Why Engineers Specify This Model
- Hot-swap I/O modules — BL67 slice modules can be replaced under power without removing the gateway or disrupting the Profibus network, minimizing downtime during maintenance.
- Auto baud-rate detection — The gateway automatically matches the Profibus master baud rate (9.6 kbit/s to 12 Mbit/s), eliminating manual configuration errors during commissioning.
- DP-V1 acyclic services — Supports parameter read/write and diagnostic data exchange beyond standard cyclic I/O, enabling advanced diagnostics from the PLC without additional hardware.
- Compact modular architecture — The BL67 system allows mixing of digital, analog, and specialty modules on a single gateway, reducing the number of Profibus nodes required.
- GSD file available — Standard TURCK GSD file enables plug-and-play integration with Siemens TIA Portal, Step 7, and all major Profibus configuration tools.
- Proven field reliability — BL67 series has a multi-decade installed base in harsh industrial environments; spare parts and replacements remain readily available.

Application-Specific FAQ
Q: Can the BL67-GW-DP be used with a Siemens S7-300 / S7-400 PLC?
A: Yes. Configure the gateway using the TURCK GSD file in Siemens STEP 7 or TIA Portal. The BL67-GW-DP is fully compatible with any Profibus DP master that conforms to EN 50170.
Q: How many I/O modules can one BL67-GW-DP support?
A: Up to 16 BL67 slice modules per gateway station, subject to the 128-byte input / 128-byte output process data limit.
Q: Is the gateway hot-swappable?
A: The I/O slice modules are hot-swappable. The gateway head itself should be replaced with the station powered down to avoid Profibus bus interruption.
Q: What is the maximum Profibus segment length?
A: At 12 Mbit/s, the maximum segment length is 100 m. At 1.5 Mbit/s it extends to 200 m, and at 93.75 kbit/s up to 1,200 m per segment (with repeaters for longer runs).
Q: Does this gateway support PROFINET? Can I migrate from Profibus to PROFINET?
A: No — the BL67-GW-DP is a Profibus DP gateway only. For PROFINET, TURCK offers the BL67-GW-PN gateway. We stock both; contact us if you are planning a migration project.
Q: What diagnostic information is available from the gateway?
A: The BL67-GW-DP provides DP-V1 acyclic diagnostics including module status, channel-level fault data, and supply voltage monitoring — accessible from the Profibus master without additional software.
