HD67580-A1 Industrial PROFIBUS Master to Modbus RTU Slave Converter DPV0

Industrial PROFIBUS master to Modbus RTU slave converter, PROFIBUS DP DPV0 support, housing type A (slim), DIN rail mount. 

The HD67580-A1 is a compact industrial gateway that bridges a PROFIBUS DPV0 Master network with Modbus RTU Slave devices on RS485. Its type A slim housing fits crowded panels, while DIN-rail mounting and pluggable screw terminals speed up installation. Engineers can add Modbus nodes to existing PROFIBUS architectures without redesigning the control layer—ideal for upgrades, brownfield projects, and mixed-vendor plants.

HD67580-A1 allows to connect Modbus masters with PROFIBUS slave devices. Converter is easy to use and configure thanks to free SW67580 sotware.

Typical applications include process automation, manufacturing lines, HVAC/BMS, and energy systems, where PROFIBUS PLCs must read from or write to Modbus RTU slaves such as meters, drives, I/O modules, and transmitters. The device supports 10/100 Base-T Ethernet for configuration and diagnostics, while data bridging occurs over PROFIBUS and RS485 with up to 115200 bps on the Modbus side. A wide operating range of -40°C to +85°C ensures reliable service in both indoor cabinets and outdoor enclosures.

Integration is straightforward: map Modbus holding/input registers and coil/discrete values into PROFIBUS process data so the PLC can access them cyclically. Use separate RS485 segments for noisy loads, respect termination and biasing practices, and keep cable shields continuous to reduce EMI. The triple isolation (Modbus/PROFIBUS, Modbus/Power Supply, PROFIBUS/Power Supply) improves robustness against ground loops and transients.

Configuration:

Thanks to the SW67580 software on your PC you can:

• Define the parameters of Modbus line
• Define the parameters of PROFIBUS
• Define the PROFIBUS network

Beyond basic setup, the tool helps assign Modbus addresses to PROFIBUS input/output bytes, set baud rate, parity, and timeouts, and verify communication using built-in diagnostics. Store and reuse project files to standardize deployments across multiple panels.

Additional advantages:

• Deterministic data exchange under PROFIBUS DPV0 cyclic communication
• LED diagnostics for power, bus status, and communication activity (quick on-site checks)
• Slim 23 mm width to save cabinet space
• Pluggable 5 mm screw terminals for quick wiring and maintenance
• RJ45 service port for fast configuration updates

Characteristics:

• Wide operating temperature range from -40°C to 85°C
• Triple isolation between Modbus/PROFIBUS, Modbus/Power Supply, PROFIBUS/Power Supply
• Mountable on 35 mm DIN rail

Best practices: keep RS485 drops short, daisy-chain devices, and terminate both ends (typically 120 Ω). Match baud rate/parity across the Modbus network, and ensure the PROFIBUS cable meets up to 6 Mbps requirements. When mixing device classes, group fast-changing signals (e.g., counters, status bits) at lower Modbus addresses to optimize polling time.
