EtherCAT - Ethernet for Control Automation Technology - is an open high performance Ethernet-based fieldbus system.

EtherCAT - Ethernet for Control Automation Technology - is an open high performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs.

TwinCAT 3 or IntervalZero

I intend to test EtherCAT communication for a new board (assume the name is XYZ). So I plan to make XYZ as the Slave and connect to a master. To make life easier for me, I decided to go with TwinCAT 3 or RTX64 as the Master on my own PC (with…
