8 Process data transfer
ƒ The process data are transmitted by means of "EtherCAT datagrams" (
¶ 39) via the
CoE process data channel.
ƒ By means of the process data the controller is operated.
ƒ The transmission of process data is time−critical.
ƒ Process data are transmitted cyclically between the host system (master) and the
controllers (slaves) (permanent exchange of current input and output data).
ƒ The master can directly access the process data. In the PLC for instance, the data are
directly stored in the I/O area.
ƒ Process data are not stored in the controller.
ƒ Process data, for instance, are setpoints, actual values, control words and status
words.
