EtherCAT reaches new dimensions in network performance. Thanks to hardware integration in the slave and direct memory access to the network controller in the master, the complete protocol processing takes place within hardware and is thus fully independent of the run-time of protocol stacks, CPU performance or software implementation. The update time for 1000 I/Os is only 30 µs – including I/O cycle time (see Table). Up to 1486 bytes of process data can be exchanged with a single Ethernet frame – this is equivalent to almost 12000 digital inputs and outputs. The transfer of this data quantity only takes 300 µs.
The communication with 100 servo axes is also extremely fast: every 100µs, all axes are provided with command values and control data and report their actual position and status. The distributed clock technique enables the axes to be synchronised with a deviation of significantly less than 1 microsecond. And even at this pace, there is more than sufficient bandwidth for asynchronous communications such as TCP/IP, parameter download or diagnostis data upload.
The extremely high performance of the EtherCAT technology enables control concepts that could not be realised with classic fieldbus systems. With EtherCAT, a communication technology is available that matches the superior computing capacity of modern Industrial PCs. The bus system is no longer the bottleneck of the control concept. Distributed I/Os are recorded faster than is possible with most local I/O interfaces. The EtherCAT technology principle is scalable and not bound to the baud rate of 100 MBaud – extension to Gigabit Ethernet is possible.
