HD67603-485-A1 PROFINET to Modbus RTU RS-485 Converter

Industrial PROFINET master to Modbus RTU slave converter, port RS-485, housing type A (slim), DIN rail mount. 

The HD67603-485-A1 is an industrial-grade protocol converter that facilitates seamless communication between a PROFINET network and a Modbus RTU Master via RS-485 interface. It is designed specifically for industrial applications where high reliability, robust isolation, and ease of configuration are required. The device enables bidirectional data exchange between systems like SIEMENS PLCs and HMI or SCADA solutions operating on Modbus RTU. This converter is particularly suitable for automation environments where PROFINET is the main control protocol, and legacy or decentralized equipment needs to be integrated into the network. Thanks to its compact housing (type A), the HD67603-485-A1 is ideal for space-limited installations in control cabinets and electrical enclosures. It features triple galvanic isolation (between Modbus–Power, Modbus–Ethernet, and Power–Ethernet), which guarantees electrical safety and protection against disturbances. The device supports up to 1440 bytes for both reading and writing, allowing efficient data handling even in demanding scenarios. This converter is a highly recommended solution for industrial sectors such as manufacturing, energy distribution, HVAC systems, building automation, and process control. With flexible configuration via dedicated PC software, the HD67603-485-A1 minimizes commissioning time and simplifies network integration projects for engineers and system integrators.

Configuration:

The converter can be quickly configured using dedicated PC software, allowing for tailored integration with your PROFINET and Modbus systems. The tool lets you:

• Define parameters for the PROFINET network including IP settings and data structure
• Define parameters for the Modbus RTU line such as baud rate, parity, and stop bits
• Specify which Modbus registers are mapped to which areas in the PROFINET memory space
• Determine how Modbus input/output data is processed within the cyclic data exchange
• Upload firmware updates and diagnostic information to the converter
