netSHIELD is an evaluation expansion board with Arduino compatible connectors for development purposes.
It enables the user to connect a Microcontroller based application to all market relevant Real-Time-Ethernet industrial networks with best-in-class real time capabilities, like PROFINET, Ethernet/IP, EtherCAT and others.
The extension board features a netX 52 system on chip. The netX SoC architecture is designed from the ground up for the highest demands on flexibility, determinism and performance in terms of multi-protocol capability and low latency for short cycle times. The heterogeneous multi-core architecture features an ARM processor core, coupled with a flexible communication subsystem (xC) for varieties of industrial applications support.
The communication subsystem, i.e. the Protocol Stack, runs completely independent on the netX SoC and requires only small memory and very limited CPU resources from the host microcontroller. A protocol specific firmware image for the netX network controller is stored in a serial flash memory.

The I-CUBE-NETX Software Expansion contains a middleware API component, called cifX API (links to Hilscher Knowledge Base). It eases access to a netX companion chip for Real Time Ethernet protocols.
The cifX middleware component API is internally based on a generic cifX Toolkit (links to Hilscher Knowledge Base).
The netX system on chip operates as an independent and flexible communication controller, beside the STM32 host Microcontroller. Industrial protocols like PROFINET, EtherCAT, Ethernet/IP, POWERLINK, Sercos III, and many others are supported by different netX firmware binaries, stored in a serial flash.
Data exchange between the STM32 application MCU and the netX protocol execution controller is performed via a dual port memory. Both chips are physically connected by a serial (SPI) or flexible parallel interface.
This STM32Cube Expansion features API functions to exchange cyclic process data between the network and the application, as well as acyclic mailbox packets.
