System on chip

Extended with CANopen and Devicenet support

The multi-protocol Netx 90 SOC (system on chip) from Hilscher has been upgraded with a loadable firmware supporting CANopen higher-layer protocol.

The CANopen protocol stack complies with the CiA 301 (v. 4.2.0) CANopen application layer and communication profile specification. The integrated object dictionary allows for a dynamic creation of objects. Monitoring functionalities such as node guarding and heartbeat increase the operational reliability of networking systems. The firmware also supports automatic baud rate-detection function enabling devices to identify the currently used communication bit-rate. Beside the netx90 SOC, company’s hardware supporting CANopen includes the Netrapid 90 carrier-board and the CifX M.2 PC card (under development).

Recently, Hilscher has also released the Devicenet firmware for Netx 90. In addition to the base functionalities of a Devicenet protocol stack, it offers extended features such as attribute change indications, module network status objects, etc.

The Netx 90 SOC as well as the products based on it (e.g. PC cards and gateways) are able to cover CANopen, Devicenet, and Profibus as well as six real-time Ethernet protocols. A change of communication firmware is sufficient to adapt the SOC to a required application. In addition, the SOC supports the IIoT (Industrial Internet of things) communication via OPC UA and MQTT. Compared to its predecessors, the netX 90 comes with a smaller form factor (10 mm x10 mm) and a reduced power loss of ≤ 1W. Communication and application tasks are architecturally separated in the core of the chip. Both sides are equipped with a 100-MHz Cortex-M4 processor. Also integrated are security functions for secure field and cloud connectivity.
