6.1.1 Control word and status word
In the control word (P967) the control requests a drive-internal state transition from
the encoTRive. In the status word (P968) the encoTRive provides information on its
actual status.
Control and status word are always process data and are consequently a fixed
constituent of the cyclic telegram; they must always be placed first in the telegram.
