Distributed Clocks Operation
In order to acquire or output data in an EtherCAT network at a certain time on all participants simultaneously,
all participants must work synchronously. For this purpose there is a local clock in the EtherCAT slave
controllers, which is automatically synchronised by the EtherCAT master with the master clock in the
EtherCAT network with an accuracy of less than 100ns.
The EtherCAT slave controllers in the EtherCAT network generate interrupts synchronously. This interrupt
collects input data or processes output data simultaneously.
Several DC modes are available on the AI4 / AO4:
