The following is part of  A Comprehensible Guide to Industrial Ethernet by Wilfried Voss.

The following information has been compiled with the best of intentions. However, as I have pointed out frequently, a fair and complete comparison of Industrial Ethernet Protocols is challenging.

Furthermore, specifications and organizational features may have changed since the time of this writing.

I have marked some parameters in red, indicating that the information was either not available or may not be entirely correct (This is especially true regarding the Profinet protocol; Siemens maintains their reputation of providing complex technologies with cryptic documentation).

Please feel free to contact me in case you find an error or when clarification is needed.

netSHIELD"NSHIELD 52-RE" - Industrial Ethernet Development Platform

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.
