Actual Value Display Of Profibus Data - BONFIGLIOLI ACTIVE Manual

10.3
For analysis purposes,
the data transmitted via the Profibus under the actual value parameters.
The parameters are in the "Actual values \ Actual values frequency inverter"
menu point of the VPlus program and can only be looked at with the latter.
In these parameters, the data transmitted via the Profibus are displayed in a proc-
essed and comprehensible form. The contents of the process data channel with con-
trol word, reference value etc. are permanently updated. As the communication chan-
nel has the contents zero in idling and transmission is very quick, 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 accordingly do not correspond to
the current state, but the last transmission.
Note:
The following diagram shows the display for an object of type PPO2. The contents
also apply for the other objects, PPO1, PPO3 and PPO4. In these objects, a part quan-
tity is displayed each time.
