Serial communication module NIC 50-DNS

ModbusDeviceNetEthernet

Product summary
Compact DIL-32 communication IC designed as a DeviceNet Slave for simple field devices without a host processor. Based on the Hilscher netX network controller, netIC integrates fieldbus/Real-Time Ethernet interface functionality including an integrated 2-port switch and hub.

Highlights

• Compact DIL-32 form factor for cost-efficient integration
• Host connection via UART or SPI with Modbus RTU support
• DeviceNet Slave interface with embedded bus logic
• Direct I/O-data connection through an external shift register (synchronous serial)
• Multi-protocol capability by firmware change (one netIC for multiple networks)

Description
The NIC 50-DNS provides a complete single-chip communication solution for field devices that require low data throughput and have no dedicated host CPU. Typical applications include barcode readers, identification systems, valve manifolds and I/O blocks. The module exposes simple read/write commands over UART or SPI, with Modbus RTU implemented as a serial protocol, enabling easy integration into host-absent devices. Conventional shift registers can be controlled as digital I/O via the synchronous serial interface, removing the need for a host processor in basic applications. The underlying netX controller ensures broad protocol support and robust network behavior.

Supported protocols

• Modbus RTU Slave
• Modbus RTU Master
• DeviceNet Slave
