Fieldbus control through a fieldbus adapter 471
Control word and Status word
The Control word is the principal means for controlling the drive from a fieldbus
system. It is sent by the fieldbus master station to the drive through the adapter
module. The drive switches between its states according to the bit-coded instructions
in the Control word, and returns status information to the master in the Status word.
The contents of the Control word and the Status word are detailed on pages
and
respectively. The drive states are presented in the state diagram (page
).
Debugging the network words
If parameter
[1], the Control word received
from the fieldbus is shown by parameter
, and the Status
word transmitted to the fieldbus network by
. This “raw” data
is very useful to determine if the fieldbus master is transmitting the correct data
before handing control to the fieldbus network.
