∗
When the encoder position P184=40 is transferred, the encoder position is
transferred into high word and the duration period of the pulses is transferred into
low word to support a duration period measurement in the slave.
If a mixture of application purposes is undertaken, e.g. master P184=44 (nominal
value) and slave with encoder coupling, then the slave must be informed using
P188=140 (in such cases only the high word is processed).
