Operation via fieldbus

a4643-1.0 HBM: public ClipX
chronized with the fieldbus, or with PROFINET IRT or EtherCAT Distributed
Clocks. The inputs and outputs of the ClipX are processed out of sync with the
fieldbus. The synchronous modes of the ClipX with these fieldbus systems pro-
vide only synchronized data transfer, not processing of the data. The processing
of queries and commands, such as the control word or access to the object dic-
tionary, normally takes additional time. In case of doubt, perform your own time
measurements with your system – see also Signal propagation times within the
ClipX and over the ClipX bus.

1 The ClipX uses these values like measured
values, for example in calculated channels
or for the limit value switches.
You can assign these values physical units
for displaying in your browser.
The values have no status information, and
so are always seen by the ClipX as valid.

1 Threshold values of the limit value switches.
The ClipX reacts to changes, then the val-
ues are applied. They are also applied
when any other value in the data changes
from the controller to the ClipX.
Fieldbus flags UINT 1 16 control flags that can be used universally
in the ClipX like internal flags, such as to
reset peak values.
These flags are transferred in the digital
flags into bits 32 … 47.
