The netHAT module upgrades a Raspberry Pi® to a Real-Time Ethernet capable slave device allowing the exchange of cyclic process data between a Pi application and a Real-Time Ethernet network. The module is compatible with the Hardware Attached on Top (HAT) specification of Raspberry. Pi and netHAT communicate via the SPI0 interface. Thanks to the multiprotocol capability of the Industrial Network controller netX the integration into networks such as PROFINET, EtherNet/IP or EtherCAT is just a matter of a firmware load procedure. The DVD includes a ready-to-use driver that configures the module to 32 bytes input and 32 bytes output fix for each of the networks. Also included are the device description files needed for the network engineering softwares during commissioning times.
Due to the module’s preconfiguration specific knowledge about network commissioning is not required. Just use the provided device description files for it and focus on your application and the PLC programming. The module demonstrates the capabilities of Hilscher’s Network Controller netX in a very simple manner. Since the netX API remains the same independent of the loaded protocol firmware an application needs to be programmed only once and hence supports any Real-Time Ethernet network.

netHAT - netX RaspberryPi® Module
The netHAT module is offered for €39.90 (VAT included).
Please read the following Q&A for further information regarding purchase options and technical advice.
Hilscher´s netHAT is available at AMAZON. For a moment, Amazon Europe offers the netHAT at Amazon.de, Amazon.fr, Amazon.es, Amazon.co.uk and Amazon.it.
With Amazon.de customers are able to export to the following countries:
France, United Kingdom, Belgium, Luxembourg, Netherlands, Spain, Italy, Portugal, Ireland, Austria, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, Greece, Hungary, Latvia, Lithuania, Malta, Poland, Romania, Slovakia, Slovenia, and Sweden
Unfortunately, Amazon North America and Amazon Japan are currently unsupported.
No. The netHAT is exclusively offered at Amazon. Customers from North America, Japan or other Countries that are not listed above please contact your nearest Hilscher subsidiaries.
The product CD that contains documentation, driver, EDS and firmware files as well as examples can be found at the "Downloads" section.
A power supply unit with at least 1800mA is required. We recommend 2A – 2.1A (for any other devices connected to the Raspberry Pi 2).
We recommend the forum of the Raspberry Pi® Foundation for questions about any issues relating to Raspberry Pi® and questions relating to the netHAT.
Some technical questions we have received are listed below.
An SD card with a storage capacity of at least 8GB should be used, since the Raspbian image is 4GB in size.
Currently only Linux is supported.
The configuration file *.nxd for the current netHAT is presently only available for 32 Byte In/Out. The stack can also be configured using the Packet API. This is much more complex and requires specific knowledge of the bus. The configuration can be found in the API manuals of the relevant protocol, which are included with the CD.
Not with the default configuration. In addition, specific knowledge of the bus is also necessary. For PROFINET, up to 4 IO-ARs and a supervisor DA AR are supported.
No, a 3D CAD model is not available.
The product CD contains “Additional Documentation” where further information on the handling of the protocol stacks by Hilscher are described.
With the standard configuration, a cycle time of 1 ms is possible for all protocols.
No, only the three systems are available for the netHAT.
The alternating blinking means that the Second Stage Loader is waiting for a firmware. This is because probably no stack package was installed.
Other expansion boards can be used between Raspberry Pi and netHAT. Alternatively, a pin header can be soldered on, and another HAT module can be inserted. These modules are not allowed to assign the pins ([24,21,19,23] SPI0, [22,18] Interrupt to netX).
Only SPI0 is used.
We recommend the Raspberry Pi® Foundation forum for questions about any issues relating to Raspberry Pi® and questions relating to netHAT https://www.raspberrypi.org/forums/.
