Can I buy the netHAT directly from Hilscher?

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.

Where can I find documentation and further information of the netHAT module?

The product CD that contains documentation, driver, EDS and firmware files as well as examples is attached here:

Which power supply unit do I require?

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). 

Whom should I contact if I have technical questions relating to the netHAT?

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.

Which SD card do I require?

An SD card with a storage capacity of at least 8GB should be used, since the Raspbian image is 4GB in size.

Can I use the netHAT with Raspberry as a master?

No, the current netHAT only surves as a slave. For master implementation, a netX Chip with more processing power (netX 100 / 500 / 4000) is needed. End of 2017 we develop a module which is master capable.

Which operating systems does the netHAT support?

Currently only Linux is supported.

Can I manage to read more than 32 Bytes or are they limited?

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.

Does the netHAT supports more than one channel?

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.

Is there a 3D CAD model of the netHAT?

No, a 3D CAD model is not available.

Where can I find documentation on the protocols?

The product CD contains “Additional Documentation” where further information on the handling of the protocol stacks by Hilscher are described.

What cycle times can be achieved when the data are received?

With the standard configuration, a cycle time of 1 ms is possible for all protocols.

Can drivers for other protocols (e.g. CC-Link or Sercos) be purchased?

No, only the three systems are available for the netHAT.

The SYS LED blinks alternately yellow and green, is this normal?

The alternating blinking means that the Second Stage Loader is waiting for a firmware. This is because probably no stack package was installed.

Can other expansion boards be used in combination with the netHAT?

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).

Which SPI pins of the Raspberry GPIO pin header uses the netHAT?

Only SPI0 is used.
