The EtherCAT data copy rate only has minor effects on the signal runtime. The advantage
between copy rates of 2.4 and 9.6 kHz is theoretically 0.16 ms, which is significantly smaller than
the statistical spread.
"Data Copy Rate" is the time in which the data are copied
to the fieldbus module in slot 0. frame_cycle is the rate of
the cyclical data frame that is set by the bus configuration
tool.
