Status Machine in Freely Configurable Mode (Rexroth
Profile Type)
Each field bus drive of Bosch Rexroth, regardless of the command
communication interface, is equipped with a uniform "status machine".
This includes a continuous structure of the parameters
P-0-4077, Field
bus: control word
and
P-0-4078, Field bus: status word
.
See Parameter Description "P-0-4077, Field bus: control word"
See Parameter Description "P-0-4078, Field bus: status word"
For this profile type the field bus control word or status word is preset by
Bosch Rexroth and cannot be changed by the user. If freely configurable
control and status bits are required, the signal control word or signal
status word has to be configured in the cyclic channel in addition to the
available field bus status word or field bus control word.
