nanoFIPdiag is a WorldFIP node dedicated to monitoring and diagnostics.
It uses the nanoFIP chip in stand-alone mode and echoes the received data; i.e. through hardwired contacts it copies the received payload to the produced one. The module is designed to be radiation-tolerant.
At CERN it is usually placed as the last slave-node of a WorldFIP segment.
The module has been designed for CERN by the company Exoligent.
