16.5 Actual Value Display of Profibus Data
For analysis purposes,
DP-Master IN 284 are displayed in the data
transmitted via the Profibus under the actual value parameters.
The parameters are situated in the "Actual values\Actual values frequency inverter"
menu of
the VPlus PC-Software.
In these parameters, the data transmitted via the Profibus are displayed in a proc
comprehensible form. The contents of the process data channel with control word,
etc. are permanently updated. As the communication chan
nel has the contents zero in idling and
transmission is very fast, the contents of the communication channel are stored on the device side
and displayed in the actual value parameters with every transmission.
The displayed content of the communication channel does not correspond to the cur

The following diagrams show the display for a configuration setting with PPO2. The PPO2 includes the
communication PKW channel for parameter access and 6 PZD objects with default settings for In-
objects.
